Embodiments of the disclosure are directed to an electronic device with a lid to manage radiation feedback. The electronic device includes a lid having at least one sidewall and a top wall, as well as a semiconductor positioned within a cavity of the lid. In certain embodiments, the lid includes at least one dielectric material and at least one internal conductive layer that is at least partially embedded within the at least one dielectric material. In certain embodiments, the lid includes dielectric material, as well as an internal wall extending from the top wall and positioned between an input port and an output port of the semiconductor. Such configurations may suppress any undesirable feedback through the lid between the input port and output port of the semiconductor.

Before delving into specific details of various aspects of the present disclosure, an overview of various elements that may be included in exemplary electronic packages of the present disclosure is provided. In particular, FIGS. 1A and 1B are views of an electronic package 100 (which may also be referred to as a semiconductor package 100).

The electronic package 100 may include a carrier 102 (which may also be referred to as a base 102). In certain embodiments, the carrier 102 may be sufficiently rigid so as to prevent undesired flexing of any components coupled thereto. Additionally, the carrier 102 may include a plurality of holes 104 suitable for receiving a fastening means, such as screws or pins. The holes 104 may allow the electronic package 100 to be affixed to a host device or system, such as a radio frequency (RF) system. The carrier 102 may be formed from electrically conductive materials, thermally conductive materials, or non-conductive materials. In certain embodiments, the carrier 102 may include metal, metal alloy, ceramic, diamond, copper, tungsten, tungsten-copper (W—Cu), and/or copper-molybdenum-copper (Cu—Mo—Cu). In other embodiments, the carrier 102 may be plated, such as with a conductive material (e.g., gold).

The electronic package 100 may include a ring structure 106 (which may also be referred to as a signal carrying component 106, a ring frame 106, etc.), which may be a printed circuit board (PCB), a laminate, substrate, a printed wiring board, a flexible circuit, a dielectric (e.g., soft dielectric), and/or another similar component comprising conductive pathways. The ring structure 106 may be coupled to the carrier 102, such as by an adhesive material (e.g., epoxy), soldering, pressure bonding, and/or temperature bonding. In certain embodiments, an adhesive material used to attach the ring structure 106 to the carrier 102 may be conductive, such as a conductive epoxy preform.

The ring structure 106 has an opening 108 therethrough. In certain embodiments, the ring structure 106 may have a plurality of outer pads 110, which may be made of a conductive material (e.g., copper). The outer pads 110 may be adapted to have one or more components (e.g., active and/or passive components) and/or leads attached thereto (e.g., via soldering). Interconnects 112 may be attached to the outer pads 110 of the ring structure 106, such as through conventional ribbon or wire bonding techniques.

In some embodiments, the ring structure 106 of the electronic package 100 may be coupled to one or more leads 114, 116 that carry a signal through the electronic package 100. The electronic package 100 may include input-side ones of the leads 114 located at a first side (e.g., an input side) of the electronic package 100 (e.g., to receive RF input signals). Output-side ones of the leads 116 are leads located at a second side (e.g., an output side) of the electronic package 100, on which the electronic package 100 may provide output signals to external circuitry/systems. Each of the input-side leads 114 and/or the output-side leads 116 may be formed of a metal or metal alloy, such as copper. The plurality of the leads 114, 116 may be tuned, positioned, and/or of different sizes to perform different signal carrying and/or routing functions.

The electronic package 100 may include at least one die 118 and/or one or more electronic components 120 attached to the carrier 102 and disposed in the opening 108 of the ring structure 106, such that the ring structure 106 surrounds the at least one die 118 and/or the one or more electronic components 120. The die 118 and/or the one or more electronic components 120 may be mechanically coupled to the carrier 102 via a solder 128 (e.g., gold-tin or other alloys) and/or another die attach.

The ring structure 106 may be electrically coupled to the die 118 through the interconnects 112. The die 118 may have a functional circuit fabricated thereon. The die 118 may include gallium arsenide (GaAs), gallium nitride (GaN), etc. The die 118 may be attached using any suitable material, such as gold-tin (AuSn) or another alloy. In certain embodiments, the die 118 includes die pads 124 on a top surface of the die 118, each of which is connected to a corresponding connecting trace 126 via the interconnects 112, such as a wire or a ribbon bond. The connecting traces 126 and the die pads 124 may be formed of any suitably conductive material, such as copper.

The one or more electronic components 120 may be attached directly to the carrier 102 and/or attached to the ring structure 106. The one or more electronic components 120 may include active components (e.g., transistors, diodes, and the like) and/or passive components (e.g., resistors, capacitors, inductors, transformers, and the like). The one or more electronic components 120 may be electrically coupled to the ring structure 106 via one or more of the interconnects 112.

A lid 130 may have a top wall 132 and a plurality of sidewalls 134 attached to the ring structure 106. Thus, the carrier 102, the ring structure 106, the input-side leads 114, the output-side leads 116, and the lid 130 may enclose the die 118 and the one or more electronic components 120 in the electronic package 100. The lid 130 may be formed from plastic, a plastic composite material, metal, metal alloy, and/or ceramic, etc. The lid 130 may be coupled to a top surface of the ring structure 106 (e.g., a surface opposite the surface of the ring structure 106 that is coupled to the carrier 102), such as by an adhesive material (e.g., epoxy, resin, acrylic, and/or silicone). The lid 130 may be coupled directly to the carrier 102 in some embodiments. In certain embodiments, the adhesive material used to attach the lid 130 to the ring structure 106 or to the carrier 102 may be non-conductive. As part of the enclosure provided by the electronic package 100, a seal ring may be formed, for example, to protect elements (e.g., a die, active components, and/or passive components) sealed in by the combination of the carrier 102, the ring structure 106, and the lid 130.

FIGS. 2A-2D are views of a lid 130(1) with an external top conductive layer 200 and an internal conductive layer 202. In particular, the lid 130(1) forms an air cavity 204 to house the die 118 (e.g., semiconductor). Although the lid 130(1) is generally of a rectangular shape, the lid 130(1) may be any of a variety of shapes and/or sizes. Use of air cavity packages in a transceiver enables higher levels of integration and lower cost assembly methods, such as compared to chip-and-wire microwave module assemblies. As operation frequency increases, package lid effects can introduce cavity-related isolation issues that can lead to performance degradation and/or oscillation issues. The lid 130(1) in this and other embodiments discussed herein may not be grounded.

The external top conductive layer 200 is at a top surface 203 of the lid 130(1). The external top conductive layer 200 may be any of a variety of sizes and/or shapes. For example, the external top conductive layer 200 may be thicker or thinner. The external top conductive layer 200 may cover only a portion of the top surface 203 of the lid 130(1).

The top wall 132 includes an upper dielectric layer 206 and a lower dielectric layer 208 with the internal conductive layer 202 positioned therebetween. The internal conductive layer 202 is embedded within the dielectric layers 206, 208, such that the internal conductive layer 202 is surrounded by dielectric material (e.g., fiber glass). The width of the internal conductive layer 202 is less than the width and/or the length of the lid 130(1). In certain embodiments, the lid 130(1) may include additional ones of the internal conductive layer 202. Further, the internal conductive layer 202 may be any size and/or shape. For example, the internal conductive layer 202 may be smaller than the external top conductive layer 200.

The lid 130(1) includes a left sidewall 134A, a right sidewall 134B, a front sidewall 134F, and a rear sidewall 134R (referred to generally as the sidewalls 134). In certain embodiments, the sidewalls 134 comprise dielectric material and are devoid of any of the internal conductive layer 202. In particular, a bottom surface 210 of the sidewalls 134 is a dielectric material and is devoid of a conductive material. This facilitates the application of the lid 130(1) to the carrier 102.

In certain embodiments, the dielectric material of the top wall 132 and/or the sidewalls 134 includes an epoxy. The conductive material of the external top conductive layer 200 and/or the internal conductive layer 202 includes metal.

FIG. 3 illustrates a side view of an electronic package 100(1) (i.e., an electronic component) with the lid 130(1) of FIGS. 2A-2D. In particular, the electronic package 100(1) (e.g., a transceiver, a monolithic microwave integrated circuit (MMIC), etc.) includes the carrier 102, the lid 130(1) attached to the carrier 102, and the die 118 (e.g., a semiconductor) housed in the air cavity 204 of the lid 130(1). An air gap 304 is formed between the die 118 and the top wall 132 of the lid 130(1). The die 118 includes an input end 300 and an output end 302. The lid 130(1) may inadvertently form a feedback signal path 306 from the output end 302 of the die 118 to the input end 300 of the die 118. This feedback may distort or negatively affect performance of the die 118. Use of the external top conductive layer 200 and/or the internal conductive layer 202 is configured to suppress the feedback signal through the feedback signal path 306 to improve performance of the die 118. In particular, the external top conductive layer 200 and/or the internal conductive layer 202 are not electrically grounded. As shown in certain embodiments, the external top conductive layer 200 and/or the internal conductive layer 202 extend between the input end 300 of the die 118 to the output end 302 of the die 118.

A user can intentionally tune the frequency response of the electronic package 100(1) by adding the conductive layers 200, 202 and/or the dielectric layers 206, 208 to the lid 130(1). Doing so can reduce undesirable resonance and feedback in the air cavity 204 and through the lid 130(1). Feedback signal suppression performance may be tuned by adjusting the location, size, and/or shape of the external top conductive layer 200, the internal conductive layer 202, and/or the air cavity 204. For example, the width, length, and/or thickness of the internal conductive layer 202 may be altered. Further, a height H1 of the air cavity 204, a height H2 of the internal conductive layer 202 to the air cavity 204, and/or a height H3 of the internal conductive layer 202 from the top surface 203 may be altered. In certain embodiments, the internal conductive layer 202 may be exposed to the air cavity 204 such that only a portion of the internal conductive layer 202 is sandwiched between the dielectric layers 206, 208. In this way, the feedback signal is altered as it propagates through the feedback signal path 306 through the top wall 132 of the lid 130(1). Such a configuration is compatible with high volume air cavity package manufacturing processes.

FIG. 4 is a chart illustrating an improvement in feedback signal suppression of the lid 130(1) of FIGS. 2A-3. As illustrated, the lid 130(1) with the internal conductive layer 202 improved suppression of the feedback signal and, thereby, improved performance of the electronic package 100(1). For example, in certain embodiments, the lid 130(1) suppresses the feedback signal level by 10 decibels (dB) at 40.5 Gigahertz (GHz) as compared to a conventional lid.

FIG. 5 illustrates a perspective view of a lid 130(2) of an electronic package 100(2) with an external top conductive layer 200(2) over only a portion of the top wall 132 of the lid 130(2). As illustrated, the external top conductive layer 200(2) only covers a portion of the top surface 203 of the top wall 132. In certain embodiments, the external top conductive layer 200(2) and/or the internal conductive layer 202 are positioned over the output end 302 of the die 118. In certain embodiments, the external top conductive layer 200(2) covers only about 50% of the top surface 203 of the lid 130(2). In certain embodiments, the external top conductive layer 200(2) covers less than 50% of the top surface 203 of the lid 130(2).

FIG. 6 illustrates a side view of a lid 130(3) with multiple internal conductive layers 202(3). In particular, the multiple internal conductive layers 202(3) are separated from each other by the dielectric material of the top wall 132 of the lid 130(3). Any number of the multiple internal conductive layers 202(3) may be used.

FIGS. 7A and 7B are views of an electronic package 100(4) with a lid 130(4) with an internal wall 700 extending between the input end 300 and the output end 302 of the die 118 in the lid 130(4). The electronic package 100(4) includes two dies 118(1), 118(2), each with the input end 300 and the output end 302. It is noted that the input end 300 of the dies 118(1), 118(2) are in line and adjacent to one another, and the output end 302 of the dies 118(1), 118(2) are also in line and adjacent to each other. Of course, fewer or more of the dies 118(1), 118(2) may be used.

The lid 130(4) includes the top wall 132 and the sidewalls 134 extending downwardly from a periphery of the top wall 132. The lid 130(4) further includes the downwardly extending internal wall 700. The internal wall 700 extends between a front sidewall 134(3) and a rear sidewall 134(4). Accordingly, the internal wall 700 separates the air cavity 204 into a first portion 702(1) proximate the left sidewall 134A and a second portion 702(2) proximate the right sidewall 134B. Further, the internal wall 700 may be offset from a center of the lid 130(4). In particular, the internal wall 700 is configured to be positioned between the input end 300 of the dies 118(1), 118(2) and the output end 302 of the dies 118(1), 118(2).

As similarly noted above, use of air cavity packages in a transceiver enables higher levels of integration and lower cost assembly methods, such as compared to chip-and-wire microwave module assemblies. As operation frequency increases, package lid effects can introduce cavity-related isolation issues that can lead to performance degradation and/or oscillation issues. The internal wall 700 of the lid 130(4) reduces feedback through the lid, thereby improving frequency response and stability.

In certain embodiments, the lid 130(4) has a height of 2 millimeters (mm) to 6 mm, or a height of at least 4 mm. In certain embodiments, a clearance is provided between a bottom 706 of the internal wall 700 and a top 708 of the dies 118(1), 118(2). In certain embodiments, the clearance is between 0.5 mm and 1.5 mm (e.g., 0.9 mm). In certain embodiments, use of the internal wall 700 improves isolation in the band by 7 dB.

FIGS. 8A and 8B are views of a lid 130(5) with conductive layers embedded within the internal wall 700. In particular, the lid 130(5) includes an external top conductive layer 800 and internal conductive layers 802. As similarly noted above, the top wall 132, the sidewalls 134, and/or the internal wall 700 include a dielectric material (e.g., fiberglass). The external top conductive layer 800 is at the top surface 203 of the lid 130(5). The external top conductive layer 800 may be any of a variety of sizes and/or shapes. For example, the external top conductive layer 800 may be thicker or thinner. The external top conductive layer 800 may cover only a portion of the top surface 203 of the lid 130(5).

The internal conductive layers 802 are embedded within the internal wall 700 and/or the sidewalls 134 such that the internal conductive layers 802 are surrounded by dielectric material (e.g., fiber glass). The internal conductive layers 802 may be any size and/or shape. Further, internal sidewall conductive layers 804A, 804B are embedded within the sidewalls 134. In certain embodiments, the internal conductive layers 802 within the internal wall 700 are positioned between the external top conductive layer 800 and the internal sidewall conductive layers 804A, 804B. In this way, the internal sidewall conductive layers 804A, 804B are positioned proximate the bottom 706 of the internal wall 700 of the lid 130(5).

Each of the external top conductive layer 800 and/or the plurality of the internal conductive layers 802, 804A, 804B are not electrically grounded and/or separated from each other by the dielectric material of the top wall 132 and/or the sidewalls 134 of the lid 130(5). Use of the conductive layers 800, 802, 804A, 804B is to modify and guide a feedback signal through the lid 130(5).

In certain embodiments, each of the external top conductive layer 800 and/or the internal conductive layers 802 include a left wide sidewall portion 806A, a right wide sidewall portion 806B, and a narrow portion 808 (which may also be referred to as a narrow internal wall portion 808) extending therebetween. In this way, the left wide sidewall portion 806A and the right wide sidewall portion 806B have widths WA, WB, and the narrow portion 808 has a width W2, where the widths WA, WB are greater than the width W2. Further, the left wide sidewall portion 806A and the right wide sidewall portion 806B have lengths LA, LB.

The internal sidewall conductive layers 804A, 804B are embedded within the sidewalls 134A, 134B. In particular, the first internal sidewall conductive layer 804A is separated from the second internal sidewall conductive layer 804B. The internal sidewall conductive layers 804A, 804B may be used to direct the feedback signal downward to the bottom 706 and the periphery of the lid 130(5).

As similarly discussed above, feedback signal suppression performance may be tuned by adjusting the location, size, and/or shape of the external top conductive layer 800 and the internal conductive layers 802, 804A, 804B. Of course, more or fewer ones of the internal conductive layers 802, 804A, 804B may be used. In certain embodiments, isolation is improved by 10 dB or more.

FIG. 9 illustrates a chart comparing the performance of various lids in suppressing feedback signals. In particular, the performance of a conventional lid 900 with a high profile lid 902, with a metal embedded lid 904, with an electronic package without a lid 906, and with an internal wall lid 908 is illustrated. As illustrated, the metal embedded lid 904 performed best within the frequency range of interest, followed by the internal wall lid 908.
