Description
FIELD OF THE PRESENT DISCLOSURE

The present application relates to improved integrated circuits with selective intrinsic alloying to reduce corrosion at liquid metal/metal interfaces, and methods of making the same.


BACKGROUND

Gallium-based (Ga-based) liquid metal alloys and their composite inks are very promising for stretchable electronics due to their high electrical conductivity and extreme deformability. However, Ga-based alloys react with other metallic contacts, such as pads or electrodes, either dissolving them or corroding them. As a result, it often causes embrittlement, and open circuit in extreme situations, at the interfaces/interconnects between liquid metal and other metallic components. This creates challenges in the use of these inks for integrated circuits due to the risk of contact degradation and instability over time.


Accordingly, there is a need in the art for improved integrated circuits with reduced corrosion at liquid metal/metal interfaces.

FIG. 1 is a block diagram schematically illustrating an electronic device 100 in accordance with some embodiments of the present disclosure. The electronic device 100 includes a substrate 110 and a first circuit 200. The first circuit 200 is formed, applied, secured, or otherwise affixed to the substrate 110.


In some embodiments, the electronic device 100 consists of only the first circuit 200. Alternatively, in some embodiments, the electronic device 100 includes the first circuit 200, and at least one additional circuit (e.g., one, two, three, four, five, or more than five additional circuits). For instance, in an embodiment, the electronic device includes an antenna circuit configured to receive or transmit wireless signals in communications with an external device and the first circuit is in communication with the antenna circuit. In some embodiments, the first circuit includes an antenna circuit configured to receive or transmit wireless signals in communications with an external device. In some embodiments, the electronic device includes one, two, three, four, five, or more than five semiconductor chips, which, in combination with the first circuit can perform some specific functions. For instance, in an embodiment, the electronic device includes one or more semiconductor chips, which in combination with the first circuit is able to wirelessly communicate with an external device based on near field communication (NFC), Wi-Fi, Bluetooth, RFID wireless communication standard, or the like.


In some embodiments, the substrate 110 is a deformable substrate. As used herein, the term “deformable substrate” refers to a substrate or a portion of it (e.g., a layer) capable of altering its shape subject to pressure or stress. For instance, in some embodiments, the substrate or at least a portion of it is flexible, bendable, stretchable, inflatable, or the like. In some embodiments, the deformable substrate or at least a portion of it (e.g., a layer) is made with a material having a Young's Modulus lower than about 0.5, lower than about 0.4 Gpa, lower than about 0.3 Gpa, or lower than about 0.2 Gpa. Such a material allows the substrate or a portion of it to deform (e.g., bend, stretch or the like) under pressure or strain. In some embodiments, the deformable substrate or at least a portion of it is made of a material having Young's Modulus lower than about 0.1 Gpa to provide enhanced flexibility and tackability. Examples of materials with low Young's Modulus include, but are not limited to elastomeric materials, viscoelastic polymeric materials, synthetic resins having low sliding performance, high corrosion resistance and high strength, such as silicone, medical grade polyurethane, polyethylene terephthalate (PET), polyimide (PI), polyphenylene sulfide (PPS) or fluorine-containing resin.


In some embodiments, the deformable substrate includes a layer or a portion made of a relatively rigid material. For instance, in some embodiments, the deformable substrate includes a layer or a portion made of a material having Young's Modulus higher than about 0.5 Gpa, higher than about 1.0 Gpa, higher than about 2.0 Gpa, higher than about 3.0 Gpa, higher than 4.0 Gpa, or higher than about 5.0 Gpa. Examples of materials with relatively higher Young's Modulus include, but are not limited to, polyethylene, PEEK, polyester, aramid, composite, glass epoxy, and polyethylene naphalate.


In some embodiments, the deformable substrate includes a supporting material upon or within an object is fabricated or attached to or on. In some embodiments, the deformable substrate or a portion of the deformable substrate is processed (e.g., patterned) during manufacture of the object. In some embodiments, the deformable substrate remains substantially unchanged when the object is formed upon or within the deformable substrate. In some embodiments, the deformable substrate includes a planar surface, a substantially planar surface, a curved surface, a round surface (e.g., an edge having a radius of curvature greater than zero), one or more sharp edges, or any combination thereof.


In some embodiments, the deformable substrate is a monolayer substrate consisting of a single layer. In some embodiments, the deformable substrate includes two, three, four, five, or more than five layers. In some embodiments, the deformable substrate includes one or more layers that are removable, e.g., functioning as a sacrificial layer that can be at least partially removed when desired or needed.


The first circuit 200 includes a plurality of circuit components. For instance, in some embodiments, the first circuit includes at least 3 circuit components, at least 5 circuit components, at least 10 circuit components, at least 50 circuit components, at least 100 circuit components, at least 500 circuit components, at least 1,000 circuit components, at least 5,000 circuit components, at least 10,000 circuit components, at least 25,000 circuit components, at least 40,000 circuit components, at least 100,000 circuit components, at least 250,000 circuit components, at least 500,000 circuit components, at least 1 million circuit components, at least 5 million circuit components, or at least 10 million circuit components.


The plurality of circuit components of the first circuit 200 includes at least 3 electrically-conductive components. As used herein, the term “electrically-conductive component” refers to a component made of a material having a resistivity of less than about 1000×10−8 ohm metre (Om), less than about 800×10−8 Ωm, less than about 600×10−8 Ωm, less than about 400×10−8 Ωm, less than about 200×10−8 Ωm, less than about 100×10−8 Ωm, less than about 80×10−8 Ωm, less than about 60×10−8 Ωm, less than about 40×10−8 Ωm, less than about 20×10−8 Ωm, less than about 10×10−8 Ωm, less than about 8×10−8 Ωm, less than about 6×10−8 Ωm, or less than about 4×10−8 Ωm. Non-limiting examples of electrically-conductive components include, but are not limited to, metal pads, electrodes, metal wires, lines, vias or the like.


In some embodiments, additionally or optionally, the plurality of circuit components of the first circuit 200 includes leads, terminals, capacitors, inductors, resistors, diodes, transistors, amplifiers, or any combination thereof.


By way of example, FIG. 1 illustrates the first circuit 200 including a first electrically-conductive component 210, a second electrically-conductive component 220 and a third electrically-conductive component 230. The first electrically-conductive component 210 is made of a first material 250 including a first metal 252, and the second electrically-conductive component 220 is made of a second material 260 including the first metal 252. Non-limiting examples of the first metal 252 include, but are not limited to, aluminum, titanium, cobalt, nickel, tin, lead, cadmium, zinc, indium, copper, silver, gold, platinum, nitinol, or tungsten or any combination thereof. For instance, in an embodiment, the first metal 252 is silver. In another embodiments, the first metal 252 is copper. In a further embodiment, the first metal 252 is a mixture of copper, silver and/or gold. In a still further embodiment, the first metal 252 is a mixture of tin, lead, cadmium, zinc, and/or indium. In some embodiments, the first metal 252 includes a metal alloy, such as nitinols (nickel-titanium alloys) or the like.


While both the first and second materials contain the first metal 252, it should be noted that the first and second materials can be the same as each other or different from each other. For instance, as a non-limiting example, in some embodiments, each of the first and second materials consists of essentially only the first metal 252 (e.g., copper or silver). As another non-limiting example, in some embodiments, one of the first and second materials consists of essentially only the first metal 252 (e.g., copper) and the other of the first and second materials is a mixture of the first metal 252 (e.g., copper) with one or more additional components other than the first metal 252 (e.g., tin, silver, gold, indium, or the like). As a further non-limiting example, in some embodiments, one of the first and second materials is a mixture of the first metal 252 (e.g., copper) and a second metal (e.g., silver) and the other of the first and second materials is a mixture of the first metal 252 (e.g., copper) and a different third metal (e.g., tin, gold, indium).


The first electrically-conductive component 210 and the second electrically-conductive component 220 can independently be any electrically-conductive component in the first circuit 200. Non-limiting examples of an electrically conductive component include, but are not limited to, a metallic pad, an electrode, a via, or a line (e.g., a conducting track or trace). For instance, in an embodiment, at least one of the first and second electrically-conductive components is a metallic pad or an electrode of the first circuit. In another embodiment, at least one of the first and second electrically-conductive components is a line of the first circuit. In a further embodiment, at least one of the first and second electrically-conductive components is a via of the first circuit.


In some embodiments, the first electrically-conductive component 210 and the second electrically-conductive component 220 form part of an active-matrix array. For instance, in some embodiments, the first electrically-conductive component 210 or the second electrically-conductive component 220 is a transistor, an electrode, or a capacitor disposed on the deformable substrate 320, and the other of the first electrically-conductive component 210 or the second electrically-conductive component 220 is different than the transistor, the electrode, or the capacitor of the first electrically-conductive component 210 or the second electrically-conductive component 220.


In some embodiments, the first electrically-conductive component 210 and the second electrically-conductive component 220 are part of a transistor switch. For instance, in some embodiments, the transistor switch is configured to control an electronical communication through the circuit 200 using a logic function, such as an OR logic function based on either a cutoff or saturation of the electronical communication. In some embodiments, two or more transistor switches are arranged (e.g., in series and/or parallel) in order to implement a logic function, such as one or more logic functions of FIG. 7.


As used herein, the term “line” refers to a conducting track or trace having a thickness less than a thickness threshold, a width less than a width threshold, or both. In some embodiments, the thickness of a line is less than about 500 μm, less than about 450 μm, less than about 400 μm, less than about 350 μm, less than about 300 μm, less than about 250 μm, less than about 200 μm, less than about 150 μm, or less than about 100 μm. In some embodiments, the width of a line is less than about 1000 μm, less than about 900 μm, less than about 800 μm, less than about 700 μm, less than about 600 μm, less than about 500 μm, less than about 400 μm, less than about 300 μm, or less than about 200 μm.


As used herein, the term “via” refers to a vertical interconnect access having a nominal (e.g., mean or average) diameter less than a diameter or width threshold. A cross section of a via can be, but does not necessarily have to be, a circle. For instance, a cross section of a via can be any regular closed form shape such as a circle or a polygon of the form N-gon, where here N is a positive integer of 3 or greater, or an irregular closed form shape, or the like.


In some embodiments, the nominal diameter or a width of a cross-section of a via is between 10 μm and 500 μm. For instance, in some embodiments, the nominal diameter or a width of a cross-section of the via is between 5 μm and 1000 μm (e.g., 0.1 centimeters (cm)), between 5 μm and 975 μm, between 5 μm and 950

The third electrically-conductive component 230 has a first end portion 232 and a second end portion 234. The first end portion 232 forms a first interface 242 with the first electrically-conductive component 210. Similarly, the second end portion 234 forms a second interface 244 with the second electrically-conductive component 220. As used herein, the term “interface” refers to a shared boundary across which two or more separate components meet and interact. For instance, the first interface 242 is the shared boundary across which the first and third electrically-conductive components meet and interact. The second interface 244 is the shared boundary across which the second and third electrically-conductive components meet and interact.


An interface between two electrically-conductive components can be formed in a variety of ways with varying configurations (e.g., shapes, sizes). For instance, as a non-limiting example, FIG. 2A is a cross-sectional view schematically illustrating an embodiment where the third electrically-conductive component 230 (e.g., a line) has the first end portion 232 partially disposed on top of the first electrically-conductive component 210 (e.g., a metallic pad) or the second end portion 234 partially disposed on the second electrically-conductive component 220 (e.g., a metallic pad). As another non-limiting example, FIG. 2B is a cross-sectional view schematically illustrating an embodiment where the third electrically-conductive component 230 (e.g., a line) has the first end portion 232 partially covered by the first electrically-conductive component 210 (e.g., a line) or the second end portion 234 partially covered by the second electrically-conductive component 220 (e.g., a line). As a further non-limiting example, FIG. 2C is a top view schematically illustrating an embodiment where the third electrically-conductive component 230 (e.g., a via) has the first end portion 232 partially covered by the first electrically-conductive component 210 (e.g., a line, a pad) or the second end portion 234 partially covered by the second electrically-conductive component 220 (e.g., a line, a pad). As a further non-limiting example, FIG. 2D is a cross-sectional view schematically illustrating an embodiment where the third electrically-conductive component 230 (e.g., a line) has the first end portion 232 partially disposed on the first electrically-conductive component 210 (e.g., a via) or the second end portion 234 partially disposed on the second electrically-conductive component 220 (e.g., a via).

In some embodiments, the thickness of the interface changes as a function of length and/or depth of the interface. For instance, in some embodiments, the width of the interface is at least 1, 2, 3, 5, 10, 15, 20, or 25 percent larger at one point in the length of the interface as it is at a second point in the length of the interface. In some embodiments, the first point in the length of the interface is the first point at which the interface has the largest cross-section and the second point is the point at which the interface has the smallest cross-section. In some embodiments, the in thickness of the interface does not appreciably or measurably change as a function of length and/or depth of the interface.

The third electrically-conductive component 230 is made of a third material 270 including a gallium-based (Ga-based) alloy 272 and a metallic filler 274, and forms an electrical conduit between the first interface and the second interface. In various embodiments, the metallic filler 274 forms intermetallic compounds with gallium. In some embodiments, the metallic filler 274 also forms intermetallic compounds with other ingredient(s) in the Ga-based alloy 272. In some embodiments, the metallic filler 274 and/or the newly formed intermetallic compounds surround the Ga-based amalgams. As such, the metallic filler 274 reduces a reactivity of the third electrically-conductive component with the first metal at the first and second interfaces so that each of the first and second interfaces is free of deterioration in conductivity for a first period of time, wherein the first period of time is at least 1000 hours.


In some embodiments, the first period of time starts after the first and second interfaces are formed. In some embodiments, the first period of time is at least 1500 hours, at least 2000 hours, at least 2500 hours, at least 3000 hours, at least 3500 hours, at least 4000 hours, at least 4500 hours, at least 5000 hours, at least 5500 hours, at least 6000 hours, at least 6500 hours, at least 7000 hours, at least 7500 hours, or at least 8000 hours. In some embodiments, the first period of time is at least 100 days, at least 150 days, at least 200 days, at least 250 days, or at least 300 days. In some embodiments, the first period of time is at least a year, at least 1.5 years, at least 2 years, at least 2.5 years, at least 3 years, at least 3.5 year, at least 4 years, at least 4.5 years, or at least 5 years.


In some embodiments, an interface (e.g., the first interface 242, the second interface 244) is free of deterioration when a second conductivity of the interface (e.g., the conductivity of the interface during the first period of time) satisfies a threshold ratio in comparison against a first conductivity of the interface (e.g., when it is initially formed, manufactured). In some embodiments, the threshold ratio is between 0.99 and 1.01, between 0.995 and 1.005, or between 0.999 and 1.001. In some embodiments, the threshold ratio is at least 0.9, at least 0.95, at least 1, at least 1.05, or at least 1.1. In some embodiments, the threshold ratio is at most 0.95, at most 0.96, at most 0.97, at most 0.98, at most 0.99, at most 0.999, at most 0.9999, at most 1, at most 1.0001, at most 1.001, at most 1.01, at most 1.02, at most 1.03, at most 1.04, at most 1.05, or at most 1.1.


In some embodiments, the substrate 110 is a deformable substrate. An interface (e.g., the first interface 242, the second interface 244) is free of deterioration in conductivity when the deformable substrate is bent, such as bent around a cylinder. In some embodiments, an interface is free of deterioration in conductivity when the deformable substrate is that has a radius of between 2 centimeters (cm) and 10 cm, between 2 cm and 8 cm, between 2 cm and 6 cm, between 2 cm and 4 cm, 4 cm and 10 cm, between 4 cm and 8 cm, between 4 cm and 6 cm, between 6 cm and 10 cm, between 6 cm and 8 cm, or between 8 cm and 10 cm for a period of time and then released. In some embodiments, the radius of the cylinder is at least 2 cm, at least 3 cm, at least 4 cm, at least 5 cm, at least 6 cm, at least 7 cm, at least 8 cm, at least 9 cm, or at least 10 cm. In some embodiments, the radius of the cylinder is at most 2 cm, at most 3 cm, at most 4 cm, at most 5 cm, at most 6 cm, at most 7 cm, at most 8 cm, at most 9 cm, or at most 10 cm.


In some embodiments, the period of time is between 10 seconds and 5 minutes, between 10 seconds and 4 minutes, between 10 seconds and 3 minutes, between 10 seconds and 2 minutes, between 10 seconds and 1 minute, between 10 seconds and 30 seconds, between 30 seconds and 5 minutes, between 10 seconds and 4 minutes, between 10 seconds and 3 minutes, between 10 seconds and 2 minutes, between 10 seconds and 1 minute, between 1 minute and 5 minutes, between 1 minute and 4 minutes, between 1 minute and 3 minutes, between 1 minute and 2 minutes, or between 3 minutes and 5 minutes. In some embodiments, the period of time is at least 10 seconds, at least 20 seconds, at least 30 seconds, at least 60 seconds, at least 1.5 minutes, at least 2 minutes, at least 2.5 minutes, at least 3 minutes, at least 3.5 minutes, at least 4 minutes, at least 4.5 minutes, or at least 5 minutes. In some embodiments, the period of time is at most 10 seconds, at most 20 seconds, at most 30 seconds, at most 60 seconds, at most 1.5 minutes, at most 2 minutes, at most 2.5 minutes, at most 3 minutes, at most 3.5 minutes, at most 4 minutes, at most 4.5 minutes, or at most 5 minutes.


In some embodiments, the metallic filler 274 reduces the reactivity of the Ga-based alloy 272 with the first metal 252 that would otherwise cause corrosion, embrittlement, degradation, or open circuit of the first electrically-conductive component 210 at the first interface 242 and corrosion, embrittlement, degradation, or open circuit of the second electrically-conductive component 220 at the second interface 244. As a result, it ensures the electrical connection between the third electrically-conductive component 230 with the first electrically-conductive component 210 at the first interface 242 and the electrical connection between the third electrically-conductive component 230 with the second electrically-conductive component 220 at the second interface 244 for a longer period of time.

The third material 270 used for making the third electrically-conductive component can include other additional or optional ingredients. For instance, in some embodiments, the third material 270 used for making the third electrically-conductive component includes a polymeric binder, a solvent, or both. In certain embodiments, the third material 270 used for making the third electrically-conductive component is a solvent-based liquid metal composition. In some embodiments, a solvent-based liquid metal composition includes the Ga-based alloy 272 and metallic filler 274 mixed with a solution that includes at least one solvent and a polymeric binder dissolved in the at least one solvent. Non-limiting examples of a solvent include, but are not limited to toluene, tetrahydrofuran (THF), cycolohexane, xylene, decane, octyle acelate, or 2,2,4-Trimethyl-1,3-pentanediol diisobutyrate (TXIB). Non-limiting examples of the polymeric binder include, but are not limited to, thermoplastic polymer, cellulose, poly(vinyl alcohol), poly(acrylic acid), polyvinylidene fluoride, polyvinyl acetate-polyvinylpyrrolidone, poly(ethylene glycol), amines, silicones, styrene isoprene styrene (SIS), styrene ethylene butylene styrene (SEBS), or any combination thereof.


The solution of a solvent-based liquid metal composition can be tailored with appropriate solvent(s) and polymer(s) to achieve desired properties, such as extended decap time or optimal viscosity. Non-limiting examples include, but are not limited to, a solution of any one or more polymers (e.g., SIS, SEBS, silicone, or the like) dissolved in TXIB, a solution of any one or more polymers dissolved in a solvent mixture including TXIB, a solution of SEBS dissolved in any solvent or solvent mixture, or a solution of a polymer mixture including SEBS dissolved in any solvent or solvent mixture.


A solvent-based liquid metal composition can have any suitable amount of the Ga-based alloy 272. For instance, in some embodiments, a solvent-based liquid metal composition includes the Ga-based alloy 272 at an amount from about 50% to about 60%, from about 60% to about 70%, from about 70% to about 80%, or from about 80% to about 90% by weight of the solvent-based liquid metal composition. In certain embodiments, the Ga-based alloy 272 includes gallium indium alloy, gallium tin alloy, gallium indium tin alloy, or gallium indium tin zinc alloy, or any combination thereof. In some embodiments, the Ga-based alloy 272 includes gallium at an amount of from about 50 wt % to about 55 wt %, from about 55 wt % to about 60 wt %, from about 60 wt % to about 65 wt %, from about 65 wt % to about 70 wt %, from about 70 wt % to about 80 wt %, or from about 80 wt % to about 85 wt % with respect to the weight of the Ga-based alloy 272.

In some embodiments, a composition of the present disclosure, at a temperature between 18° C. and 22° C., has a viscosity of at most 500 cps, at most 600 cps, at most 700 cps, at most 800 cps, at most 900 cps, at most 1,000 cps, at most 1,100 cps, at most 1,200 cps, at most 1,300 cps, at most 1,400 cps, at most 1,500 cps, at most 1,600 cps, at most 1,700 cps, at most 1,800 cps, at most 1,900 cps, at most 2,000 cps, at most 2,100 cps, at most 2,200 cps, at most 2,300 cps, at most 2,400 cps, at most 2,500 cps, at most 2,600 cps, at most 2,700 cps, at most 2,800 cps, at most 2,900 cps, or at most 3,000 cps.

For instance, in some embodiments, a composition of the present disclosure has a measured conductivity of greater than about 3×105 S/m (siemens per meter), greater than about 4×105 S/m, greater than about 5×105 S/m, greater than about 6×105 S/m, greater than 7×105 S/m, greater than 8×105 S/m, greater than 9×105 S/m, greater than 1×106 S/m, greater than 1.1×106 S/m, or greater than 1.2×106 S/m.


In some embodiments, the substrate 110 includes one or more layers, and the first, second and third electrically-conductive components are in a common layer of the substrate 110. For instance, by way of example, FIG. 5A illustrates a first set of first electrically-conductive components 210 and a second set of second electrically-conductive components 220 formed on a common layer, e.g., a first layer 110-1, of the substrate. The first set of first electrically-conductive components 210 is made of a first material 250 including the first metal 252 (e.g., Ag). The second set of second electrically-conductive components 220 is made of a second material 260 including the first metal 252 (e.g., Ag). FIG. 5B illustrates a third set of third electrically-conductive components 230 formed on the first layer 110-1 of the substrate. The third set of third electrically-conductive components 230 is made of a third material 270 including a Ga-based alloy 272 and a metallic filler 274. As shown, a third electrically-conductive component 230 has a first end portion 232 and a second end portion 234. The first end portion 232 of the third electrically-conductive component 230 overlays a portion of a first electrically-conductive component 210 and thus forms a first interface in between. The second end portion 234 of the third electrically-conductive component 230 overlays a portion of a second electrically-conductive component 220 and thus forms a second interface in between. In some embodiments, each third electrically-conductive component in the third set of third electrically-conductive components is a line.


In some embodiments, the substrate 110 includes a plurality of layers with the first and second electrically-conductive components in different layers of the substrate. For instance, by way of example, FIG. 6E illustrates the substrate including at least a layer 110-1 and a layer 110-2. A first set of first electrically-conductive components 210 is formed on the first layer 110-1, and a second set of second electrically-conductive components 220 is formed on the second layer 110-2. The first set of first electrically-conductive components 210 is made of a first material 250 including the first metal 252 (e.g., Ag, Au, Ti, NiTi, W, or Cu). The second set of second electrically-conductive components 220 is made of a second material 260 including the first metal 252 (e.g., Ag, Au, Ti, NiTi, W, or Cu). A third set of third electrically-conductive components 230 is formed between the first and second third electrically-conductive components. The third set of third electrically-conductive components 230 is made of a third material 270 a Ga-based alloy 272 and a metallic filler 274. As shown, a third electrically-conductive component 230 has a first end portion forming a first interface 242 with a first electrically-conductive component 210 and a second end portion forming a second interface 244 with a second electrically-conductive component 220. In some embodiments, each third electrically-conductive component in the third set of third electrically-conductive components is a via. While FIG. 6E illustrates that the second layer 110-2 is adjacent to the first layer 110-1, it should be noted that the present disclosure is not limited thereof. For instance, in some embodiments, a first electrically-conductive component is in a first layer and a second electrically-conductive component is in a second layer that is separated from the first layer by one, two, three, four, five or more than five layers.


Since the third electrically-conductive component 230 is made of the third material 270 including the Ga-based alloy 272 and the metallic filler 274, the reactivity of the third electrically-conductive component with the first metal 252 at the first and second interfaces is reduced. This reduces the deterioration (e.g., corrosion, degradation, embrittlement) of the first electrically-conductive component 210 at the first interface 242 and deterioration of the second electrically-conductive component 220 at the second interface 244, and thus improves the integrity and stability of the circuit.


In some embodiments, the first set of first electrically-conductive components 210 consists of a single first electrically-conductive component. Alternatively, in some embodiments, the first set of first electrically-conductive components 210 includes at least 2, at least 3, at least 4, at least 5, at least 10, at least 20, at least 30, at least 40, or at least 50 first electrically-conductive components. Similarly, in some embodiments, the second set of second electrically-conductive components 220 consists of a single second electrically-conductive component. Alternatively, in some embodiments, the second set of second electrically-conductive components 220 includes at least 2, at least 3, at least 4, at least 5, at least 10, at least 20, at least 30, at least 40, or at least 50 second electrically-conductive components. In some embodiments, the third set of third electrically-conductive components 220 consists of a single third electrically-conductive component. Alternatively, in some embodiments, the third set of third electrically-conductive components 220 includes at least 2, at least 3, at least 4, at least 5, at least 10, at least 20, at least 30, at least 40, or at least 50 third electrically-conductive components.


In some embodiments where the third set of third electrically-conductive components includes a plurality of traces, adjacent traces are separated by a distance greater than a distance threshold. In some embodiments, adjacent traces are separated by a distance of at least about 20 μm, at least about 40 μm, at least about 60 μm, at least about 80 μm, at least about 100 μm, at least about 120 μm, at least about 140 μm, at least about 160 μm, at least about 180 μm, or at least about 200 μm.


In some embodiments, the first circuit 200 includes a plurality of first electrically-conductive components made of a first material 250 including a first metal 252, a plurality of second electrically-conductive components made of a second material 260 including the first metal 252, and a plurality of third electrically-conductive components made of a third material 270 including a Ga-based alloy 272 and a metallic filler 274. Moreover, at least one first electrically-conductive component in the plurality of first electrically-conductive components is in a common layer with at least one second electrically-conductive component in the plurality of second electrically-conductive components and in a different layer with at least another second electrically-conductive component in the plurality of second electrically-conductive components. Further, the plurality of third electrically-conductive components includes at least one trace and at least one via.


For instance, by way of example, FIG. 3 illustrates the first circuit 200 includes a plurality of first electrically-conductive components 210-1, 210-2 and 210-3, and a plurality of second electrically-conductive components 220-1, 220-2 and 220-3. The second electrically-conductive component 220-1 is in a layer 110-2. The first electrically-conductive component 210-3 and the second electrically-conductive component 220-3 are in a layer 110-3. The first electrically-conductive component 210-2 is in a layer 110-4. The first electrically-conductive component 210-1 and the second electrically-conductive component 230-3 are in a layer 110-5.


The first circuit 200 also includes a plurality of third electrically-conductive components 230-1, 230-2, 230-3, 230-4 and 230-5. The third electrically-conductive component 230-1 is a via, and electrically connects the first electrically-conductive component 210-1 and the second electrically-conductive component 220-1 that are in two different layers. Similarly, the third electrically-conductive component 230-2 is a via, and electrically connects the first electrically-conductive component 210-2 and the second electrically-conductive component 220-2 that are in two different layers. The third electrically-conductive component 230-3 is a via, and electrically connects the first electrically-conductive component 210-3 and the second electrically-conductive component 220-3 that are in two different layers. The third electrically-conductive component 230-4 is a trace or a plurality of traces, and electrically connects the first electrically-conductive component 210-3 and the second electrically-conductive component 220-2 that are in the common layer 110-3. Similarly, the third electrically-conductive component 230-5 is a trace or a plurality of traces, and electrically connects the first electrically-conductive component 210-1 and the second electrically-conductive component 220-3 that are in the common layer 110-5.


Referring now to FIG. 4, there is depicted a flow chart illustrating an exemplary method 400 for manufacturing an electronic device such as the electronic device 100. The method 400 includes forming a first electrically-conductive component at a first portion of a substrate (block 402), and forming a second electrically-conductive component at a second portion of the substrate (block 404). The first electrically-conductive component is made of a first material 250 including a first metal 252 (e.g., Ag, Au, Cu, Ti, NiTi, or W). The second electrically-conductive component is made of a second material 260 including the first metal 252 (e.g., Ag, Au, Cu, Ti, NiTi, or W). As disclosed elsewhere herein, while both the first and second materials include the first metal 252, the first and second materials can be the same or different.


The method 400 also includes connecting the second electrically-conductive component with the first electrically-conductive component by a third electrically-conductive component (block 406). The third electrically-conductive component is made of a third material 270 including a Ga-based alloy 272 and a metallic filler 274. The metallic filler 274 is selected such that it reduces a reactivity of the Ga-based alloy 272 with the first metal 252, and thus minimizes deterioration of the first and second electrically-conductive components at the interfaces over time. For instance, in some embodiments, the metallic filler reduces a reactivity of the third electrically-conductive component with the first metal at the first and second interfaces so that each of the first and second interfaces is free of deterioration in conductivity for a period of time (e.g., at least 1000 hours, at least 1500 hours, at least 2000 hours, at least 2500 hours, at least 3000 hours, at least 3500 hours, at least 4000 hours, at least 4500 hours, at least 5000 hours, at least 5500 hours, at least 6000 hours, at least 6500 hours, at least 7000 hours, at least 7500 hours, at least 8000 hours, at least 100 days, at least 150 days, at least 200 days, at least 250 days, at least 300 days, at least a year, at least 1.5 years, at least 2 years, at least 2.5 years, at least 3 years, at least 3.5 year, at least 4 years, at least 4.5 years, or at least 5 years).


Referring to FIGS. 5A-5D, in some embodiments, the third electrically-conductive component is a line. For instance, to form a line that couples the first electrically-conductive component and second electrically-conductive component, in some embodiments, the method forms the first and second electrically-conductive components on a common layer of the substrate. As a non-limiting example, FIG. 5A illustrates that the method forms a first set of first electrically-conductive components 210 and a second set of second electrically-conductive components 220 on a common layer, e.g., a first layer 110-1, of the substrate 110. In particular, the first set of first electrically-conductive components 210 is formed on a first portion of the common layer of the substrate 110, and the second set of second electrically-conductive components 220 is formed on a second portion of the common layer of the substrate 110. In some embodiments, each of the first and second electrically-conductive components is made of a material including the first metal 252 (e.g., Cu, Au, Ag, Ti, NiTi, W, or a combination thereof).


The method then forms a third set of third electrically-conductive components 230, as illustrated in FIG. 5B, to couple the first set of first electrically-conductive components and the second set of second electrically-conductive components. As shown, a third electrically-conductive component 230 has a first end portion 232 and a second end portion 234. The first end portion 232 of the third electrically-conductive component 230 overlays a portion of a first electrically-conductive component 210 and thus forms a first interface in between. The second end portion 234 of the third electrically-conductive component 230 overlays a portion of a second electrically-conductive component 220 and thus forms a second interface in between.


In some embodiments, a second layer 110-2 is applied to encapsulate at least a portion of the first layer 110-1, for instance, using a slot-die coating technique, as illustrated in FIG. 5C. In some embodiments, the second layer 110-2 is made of a material including Si. In some embodiments, epoxy micro-dispensing is performed as illustrated in FIG. 5D.


Referring to FIGS. 6A-6E, in some embodiments, the third electrically-conductive component is a via. To form a via that couples the first electrically-conductive component and second electrically-conductive component, in some embodiments, the method forms the first and second electrically-conductive components on two different layers (one layer being a first portion and the other being a second portion) of the substrate 110. As a non-limiting example, in some embodiments, the method forms a first set of first electrically-conductive components 210 on a first layer 110-1 of the substrate 110, as illustrated in FIG. 6A. The first electrically-conductive component is made of a first material 250 including a first metal 252 (e.g., Ag, Au, Cu, Ti, NiTi, or W).


The method then overlays a second layer 110-2 on the first layer 110-1, for instance, using a slot-die coating technique, as illustrated in FIG. 6B. The second layer 110-2 encapsulates at least a portion of the first set of first electrically-conductive components 210. The method then creates a set of channels 240, for instance, using a laser or the like, through the second layer 110-2, as illustrated in FIG. 6C. In some embodiments, each channel is extended to a first electrically-conductive component in the first set of the first electrically-conductive components. The set of channels is filled, for instance, using extrusion-based additive manufacturing method such as direct printing techniques, with a third material 270 (i.e., a material including a Ga-based alloy 272 and a metallic filler 274), to form a third set of third electrically-conductive components 230, as illustrated in FIG. 6D. In some embodiments, each third electrically-conductive component 230 is a via. A third electrically-conductive component 230 has a first end portion forming a first interface 242 with the first electrically-conductive component 210.


After that, the method forms a second set of second electrically-conductive components 220 on the second layer 110-2, as illustrated in FIG. 6E. The second set of second electrically-conductive components 220 is made of a second material 260 including the first metal 252 (e.g., Ag, Au, Cu, Ti, NiTi, or W). A third electrically-conductive component 230 has a second end portion forming a second interface 244 with the second electrically-conductive component 220. In some embodiments, each second circuit in the second set of second electrically-conductive components 220 contacts a third electrically-conductive component in the third set of third electrically-conductive components 230.


The third electrically-conductive component 230 is made of a third material 270 disclosed herein, i.e., a material including a Ga-based alloy 272 and a metallic filler 274, and/or other optional/additional ingredient(s) such as a polymeric binder, solvent(s) or the like. In various embodiments, the metallic filler 274 forms intermetallic compounds with gallium and/or with other ingredient(s) in the Ga-based alloy 272. In some embodiments, the metallic filler 274 and/or the newly formed intermetallic compounds surround the Ga-based amalgams. As such, the metallic filler 274 reduces a reactivity of the third electrically-conductive component at the first and second interfaces, and thus minimizes deterioration of the first electrically-conductive component and the second electrically-conductive component over time. For instance, in some embodiments, the metallic filler reduces a reactivity of the third electrically-conductive component with the first metal at the first and second interfaces so that each of the first and second interfaces is free of deterioration in conductivity for a period of time (e.g., at least 1000 hours, at least 1500 hours, at least 2000 hours, at least 2500 hours, at least 3000 hours, at least 3500 hours, at least 4000 hours, at least 4500 hours, at least 5000 hours, at least 5500 hours, at least 6000 hours, at least 6500 hours, at least 7000 hours, at least 7500 hours, at least 8000 hours, at least 100 days, at least 150 days, at least 200 days, at least 250 days, at least 300 days, at least a year, at least 1.5 years, at least 2 years, at least 2.5 years, at least 3 years, at least 3.5 year, at least 4 years, at least 4.5 years, or at least 5 years). In some embodiments, the third set of third electrically-conductive components 230 is formed by an extrusion-based additive manufacturing method such as direct printing techniques.


In some embodiments, the first set of first electrically-conductive components 210 consists of a single first electrically-conductive component. Alternatively, in some embodiments, the first set of first electrically-conductive components 210 includes at least 2, at least 3, at least 4, at least 5, at least 10, at least 20, at least 30, at least 40, or at least 50 first electrically-conductive components. Similarly, in some embodiments, the second set of second electrically-conductive components 220 consists of a single second electrically-conductive component. Alternatively, in some embodiments, the second set of second electrically-conductive components 220 includes at least 2, at least 3, at least 4, at least 5, at least 10, at least 20, at least 30, at least 40, or at least 50 second electrically-conductive components. In some embodiments, the third set of third electrically-conductive components 220 consists of a single third electrically-conductive component. Alternatively, in some embodiments, the third set of third electrically-conductive components 220 includes at least 2, at least 3, at least 4, at least 5, at least 10, at least 20, at least 30, at least 40, or at least 50 third electrically-conductive components.


The line or via can be formed using, for instance, an extrusion-based additive manufacturing method such as direct printing techniques. In some embodiments, the third material 270 includes a polymeric binder, or is a solvent-based liquid metal composition disclosed herein. In such embodiments, subsequent to the forming of the third electrically-conductive component, the polymeric binder or at least a portion of it polymerizes thereby forming the line or via that couples, and electrically connects, the first electrically-conductive component and second electrically-conductive component. For instance, in some embodiments, to obtain higher conductivity, after the forming, the circuit is allowed to cure. In an embodiment, the circuit is allowed to cure at room temperature for at least 4 hours, at least 6 hours, at least 8 hours, at least 10 hours, at least 12 hours, at least 14 hours, at least 16 hours, at least 18 hours, at least 20 hours, at least 22 hours, or at least 24 hours. In another embodiment, the circuit is allowed to cure at an elevated temperature, for instance, between 40° C. to 80° C., for less than 10 hours, less than 8 hours, less than 6 hours, less than 4 hours, less than 2 hours, or less than 1 hour.


Referring to FIG. 8, there is shown interactions between a liquid metal (EGaIn) and different interconnect materials. The interconnect materials are silver (Ag), gold (Au), copper (Cu), nickel (Ni), and tin (Sn). The images were taken after the testing samples had been placed in a chamber for 500 hours and during 500 hours for 500 thermal cycles from −30° C. to 75° C. This thermal cycling test simulates extremely harsh environmental conditions. As can be seen, Ag, Au, Cu and Sn all react with EGaIn in some degrees and deteriorates the interconnection. Among the tested samples, only Ni shows no visible reaction with EGaIn after 500 hours of thermal cycles. In other words, as an interconnect material to be used with EGaIn, Ni is chemically more stable than Ag, Au, Cu and Sn.


Referring to FIG. 9, there is shown a plot of measured resistances of testing samples with different interconnect materials. The testing samples are the EGaIn/Cu sample (i.e., an EGaIn channel with a copper wire electrical terminal), the EGaIn/Ti sample (i.e., an EGaIn channel with a titanium wire electrical terminal), the EGaIn/NiTi sample (i.e., an EGaIn channel with a nitinol wire electrical terminal), and the EGaIn/W sample (i.e., an EGaIn channel with a tungsten wire electrical terminal). The resistance of the LM-channels were measured using LCR-meter Keysight E4880AL (frequency 1.5 kHz, 1 V). The measurement was conducted at four different time points: before the thermal cycling test, after 150 hours of thermal cycles, after 300 hours of thermal cycles and after 500 hours of thermal cycles. All thermal cycles were from −30° C. to 75° C. The resistance values in the plot are for the samples at 0% strain, i.e., the samples were not stretched at any time during this experiment. As can be seen, there is no significant change of resistance after 500 hours of thermal cycles for all four samples.


Referring to FIGS. 10-12, there are shown images of testing samples taken at three time points. Images in FIG. 10 were taken after 150 hours of thermal cycles. As can be seen, there is no visible change for all four samples. Images in FIG. 11 were taken after 300 hours of thermal cycles. As can be seen, the color of the EGaIn/Cu sample is getting dark, indicating that EGaIn is reacting with Cu. There is no visible change for the EGaIn/Ti, EGaIn/NiTi, and EGaIn/W samples. Images in FIG. 12 were taken after 500 hours of thermal cycles. As can be seen, the EGaIn oxide is forming through the ends in the EGaIn/Cu sample. There is no visible change for the EGaIn/Ti, EGaIn/NiTi, and EGaIn/W samples. This indicates that Ti, NiTi and W are not reacting with EGaIn during 500 hours of thermal cycles from −30° C. to 75° C.


Referring to FIG. 13, there are shown resistance graphs of the EGaIn/Cu sample. The resistances were measured at four different time points: before the thermal cycling test, after 150 hours of thermal cycles, after 300 hours of thermal cycles and after 500 hours of thermal cycles from −30° C. to 75° C.


Referring to FIGS. 14-17, there are shown chemical reactivity of EGaIn with copper after 500 hours of thermal cycles. For comparison, FIG. 14 shows a pristine Cu wire in the two images on the left side and the EGaIn/Cu sample after 500 hours of thermal cycles from −30° C. to 75° C. in the remaining four images. As can be seen, after 500 hours of thermal cycles, there are large CuGaz crystals (>20 μm) formed on the edges of the wire. There are also small CuGaz particles (<5 μm) formed toward the center of the Cu wire. FIG. 15 shows images of the EGaIn/Cu sample after 500 hours of thermal cycles and analysis results using an energy dispersive spectroscopy (EDS) that determines the chemical elements and their relative abundance. As can be seen, gallium reacts to Cu to form cubic CuGaz at location 1 on the EDS layered image, and excess of EGaIn is formed at location 2 (the Cu wire surface) on the EDS layered image. FIG. 16 shows the formation of cubic CuGaz. FIG. 17 shows, in the upper two images, elemental mapping of the EGaIn/Cu sample (i.e., the Cu wire after 500 hours of thermal cycles in contact with EGaIn). FIG. 17 also shows, in the lower left plot, the distribution of the thickness of the corroded layer. For the tested EGaIn/Cu sample, it is found that the thickness of CuGaz is 9±4 FIG. 17 further shows, in the lower middle and right plots, a spectrum of the Cu wire surface and a spectrum of the inner Cu layer that confirm the presence of CuGaz.


Referring to FIG. 18, there are shown resistance graphs of the EGaIn/NiTi sample. The resistances were measured at four different time points: before the thermal cycling test, after 150 hours of thermal cycles, after 300 hours of thermal cycles and after 500 hours of thermal cycles from −30° C. to 75° C.


Referring to FIGS. 19 and 20, there are shown chemical reactivity of EGaIn with NiTi (nitinol) after 500 hours of thermal cycles. For comparison, FIG. 19 shows a pristine NiTi wire in the two images on the left side and the EGaIn/NiTi sample after 500 hours of thermal cycles from −30° C. to 75° C. in the two images on the right side. As can be seen, after 500 hours of thermal cycles, there is no visible alloying or corrosion. FIG. 20 shows images of the test sample after 500 hours of thermal cycles and EDS analysis results. Specifically, FIG. 20 shows, on the left side, a top view image of the EGaIn/NiTi sample and a spectrum of the NiTi surface. As can be seen, there are only small droplets of EGaIn on the NiTi surface. FIG. 20 also shows, on the right side, cross-sectional images of the NiTi wire. As can be seen, there is no Ga-alloying or corrosion. This indicates that NiTi is not reacting with EGaIn during 500 hours of thermal cycles from −30° C. to 75° C.


Referring to FIG. 21, there are shown resistance graphs of the EGaIn/Ti sample. The resistances were measured at four different time points: before the thermal cycling test, after 150 hours of thermal cycles, after 300 hours of thermal cycles and after 500 hours of thermal cycles from −30° C. to 75° C.


Referring to FIG. 22, there are shown chemical reactivity of EGaIn with Ti after 500 hours of thermal cycles. Specifically, FIG. 22 shows, on the left side, a top view image of the EGaIn/Ti sample and a spectrum of the Ti surface. As can be seen, there are only very small amount of EGaIn on the Ti wire surface. FIG. 22 also shows, on the right side, a cross-sectional image of the Ti wire and a spectrum of the inner Ti layer. As can be seen, there is no Ga-alloying or corrosion. This indicates that Ti is not reacting with EGaIn during 500 hours of thermal cycles from −30° C. to 75° C.


Referring to FIG. 23, there are shown resistance graphs of the EGaIn/W sample. The resistances were measured at four different time points: before the thermal cycling test, after 150 hours of thermal cycles, after 300 hours of thermal cycles and after 500 hours of thermal cycles from −30° C. to 75° C.


Referring to FIGS. 24 and 25, there are shown chemical reactivity of EGaIn with W (tungsten) after 500 hours of thermal cycles. For comparison, FIG. 24 shows a pristine W wire in the two images on the left side and the EGaIn/W sample after 500 hours of thermal cycles from −30° C. to 75° C. in the two images on the right side. As can be seen, after 500 hours of thermal cycles, there is no visible alloying or corrosion. FIG. 25 shows images of the test sample after 500 hours of thermal cycles and EDS analysis results. Specifically, FIG. 25 shows, on the left side, a top view image of the EGaIn/W sample and a spectrum of the W surface. As can be seen, there is almost no EGaIn on the W wire surface. FIG. 25 also shows, on the right side, cross-sectional images of the W wire. As can be seen, there is no Ga-alloying or corrosion. This indicates that W is not reacting with EGaIn during 500 hours of thermal cycles from −30° C. to 75° C.


In summary, the thermal cycling tests show that NiTi, Ti, and W are not reacting with EGaIn and are chemically stable during 500 hours of thermal cycles from −30° C. to 75° C. As such, NiTi, Ti, and W can be used along with EGaIn to reduce corrosion at liquid metal/metal interfaces and thus improve the integrity and stability of circuits even in very harsh environmental conditions.
