2. Description of Related Art

With the vigorous development of the electronic industry, electronic products are also gradually developing toward the trend of multi-function and high performance. Technologies currently applied in the field of chip packaging include flip-chip packaging modules such as chip scale package (CSP), direct chip attached (DCA), multi-chip module (MCM), or the like.


As shown in FIG. 1, in a method of manufacturing a conventional semiconductor package 1, a semiconductor chip 11 is first disposed on a packaging substrate 10 with an active surface 11a of the semiconductor chip 11 by flip-chip bonding (i.e., via conductive bumps 110 and an underfill 111). Then, a heat sink 13 is bonded on an inactive surface 11b of the semiconductor chip 11 with a top sheet 130 of the heat sink 13 by a thermal interface material (TIM) layer 12, and supporting legs 131 of the heat sink 13 are disposed on the packaging substrate 10 via metal glue 14. Afterward, an encapsulation molding operation is performed to provide a packaging colloid (not shown) to cover the semiconductor chip 11 and the heat sink 13, and the top sheet 130 of the heat sink 13 is exposed from the packaging colloid.


In the conventional semiconductor package 1, the metal glue 14 can be bonded to ground pads (not shown) of the packaging substrate 10, such that the heat sink 13 can be used as a shielding structure to protect the semiconductor chip 11 from electromagnetic interference (EMI).


However, in the conventional semiconductor package 1, the heat sink 13 is required to be deployed to provide the heat dissipation and shielding functions for the semiconductor chip 11, so that the supporting legs 131 of the heat sink 13 will occupy an extremely large use area of the packaging substrate 10 and are not conducive to reducing the use area of the circuit board, thereby failing to achieve the purpose of integration.


Besides, the semiconductor chip 11 and the heat sink 13 are respectively placed on the single packaging substrate 10, thereby greatly increasing process time, resulting in the inability to achieve the purpose of mass production.

FIG. 2A-1, FIG. 2B-1, FIG. 2C-1 and FIG. 2D-1 are schematic cross-sectional views illustrating a method of manufacturing an electronic package 2 according to the present disclosure.


As shown in FIG. 2A-1, a plurality of electronic components 21 are disposed on a carrier 9 including a plurality of substrate structures 20, and a plurality of conductive components 22 are formed on the carrier 9 and disposed between adjacent ones of the substrate structures 20. Then, an encapsulation layer 23 is formed on the carrier 9, so that the plurality of electronic components 21 and the plurality of conductive components 22 are covered by the encapsulation layer 23.


The carrier 9 is of a strip form or a full-panel specification, so that the plurality of substrate structures 20 are arranged in an array, as shown in FIG. 2A-2, such that a separation line L (e.g., a separation boundary line) is defined between adjacent ones of the substrate structures 20.


In an embodiment, the substrate structure 20 is, for example, a packaging substrate with a core layer and a circuit structure, or a packaging substrate with a coreless circuit structure. The substrate structure 20 has a plurality of circuit layers, such that the circuit layer has a plurality of electrical contact pads 201 and a plurality of ground pads 202 on one side of the carrier 9. For instance, in an electronic package as shown in FIG. 5, a substrate structure 50 can be a packaging substrate with coreless circuit structure and has fan-out redistribution layer (RDL). It can be understood that the substrate structures 20 can also be other carrier structures (e.g., silicon interposers, lead frames, or the like) for carrying electronic components such as chips, but the present disclosure is not limited to as such.


Furthermore, the ground pads 202 can be arranged on the substrate structures 20 according to requirements, such as an edge area as shown in FIG. 2A-2 or a corner area as shown in FIG. 2A-3, but the present disclosure is not limited to as such.


The electronic component 21 is an active element, a passive element, or a combination of the active element and the passive element, wherein the active element is for example a semiconductor chip, and the passive element is for example a resistor, a capacitor, or an inductor.


In an embodiment, the electronic component 21 is a semiconductor chip and has an active surface 21a and an inactive surface 21b opposing the active surface 21a, and a plurality of electrode pads 210 are formed on the active surface 21a. Further, the electronic component 21 is bonded onto the substrate structure 20 with the inactive surface 21b via a bonding layer 200, and the electrode pads 210 on the active surface 21a are electrically connected to the electrical contact pads 201 by wires 211 such as bonding wires via wire bonding.

It can be understood that there are many ways to electrically connect the electronic component 21 to the substrate structure 20, and the required type and quantity of the electronic component that can be disposed on the substrate structure 20 are not limited to the above.


Additionally, at least one electronic component 21 can be disposed on the single substrate structure 20 according to requirements, such as one electronic component 21 as shown in FIG. 2A-1 or the plurality of electronic components 21, 61 as shown in FIG. 6.


The conductive components 22 are bonding wires for a wire-bonding process and have a structure similar to that of the wires 211, and the conductive components 22 are arranged on the substrate structures 20 and spaced apart from the electronic components 21, such that the conductive components 22 are in contact with and bonded onto the ground pads 202 of the substrate structures 20, so that the conductive components 22 are electrically connected to the substrate structures 20.


In an embodiment, opposing ends of the plurality of conductive components 22 are bonded onto the ground pads 202 of two adjacent ones of the substrate structures 20 of the carrier 9 respectively, as shown in FIG. 2A-2.


Moreover, based on the arrangement of the ground pads 202, the conductive component 22 can be arranged across side areas of two adjacent ones of the substrate structures 20, as shown in FIG. 2A-2; alternatively, the conductive component 22 can also be arranged across corner areas of two adjacent ones of the substrate structures 20, as shown in FIG. 2A-3.


Furthermore, when the conductive component 22 is arranged across corner areas of two adjacent ones of the substrate structures 20, a bonding wire for wire bonding can be used as a connector 29, such that opposing two ends of the connector 29 are connected to the conductive components 22 on the two substrate structures 20 respectively, as shown in FIG. 2A-3, and the connector 29 is also connected to the ground pads 202 of two adjacent ones of the substrate structures 20.


The encapsulation layer 23 is defined with a first surface 23a and a second surface 23b opposing the first surface 23a, wherein the encapsulation layer 23 is bonded onto each of the substrate structures 20 with the first surface 23a of the encapsulation layer 23 to form a packaging module 2a including the substrate structure 20, the electronic component 21 and the encapsulation layer 23.


In an embodiment, the encapsulation layer 23 is made of an insulating material such as polyimide (PI), dry film, packaging colloid of epoxy resin, or molding compound. For instance, the encapsulation layer 23 can be formed on the substrate structures 20 by liquid compound, injection, lamination, compression molding, or the like.


Additionally, a heat dissipation structure 25 such as an adhesive metal sheet or a plated metal layer can be formed on the second surface 23b of the encapsulation layer 23 of each of the packaging modules 2a according to requirements.


As shown in FIG. 2B-1, a recess 220 is formed on the separation line L between two adjacent ones of the packaging modules 2a, such that the recess 220 penetrates through the heat dissipation structure 25 and extends into the encapsulation layer 23, so that each of the conductive components 22 is separated into two conductors 22a.


In an embodiment, the conductors 22a are exposed from sidewall surfaces of the recess 220.


Moreover, the depth of the recess 220 can be designed according to requirements. For instance, the recess can penetrate through the encapsulation layer 23 and extend to the substrate structures 20, such as a recess 320 penetrating through the substrate structures 20 (or the packaging modules 2a) as shown in FIG. 2B-2, or a recess 420 free from penetrating through the substrate structures 20 as shown in FIG. 2B-3.


As shown in FIG. 2C-1, subsequent to a manufacturing process shown in FIG. 2B-1, a conductive layer 24 is formed on the surfaces of the packaging modules 2a and the sidewall surfaces of the recess 220, so that the conductive layer 24 is in contact with the conductors 22a for shielding.


In an embodiment, the conductive layer 24 is a metal layer and is made from for example gold (Au), silver (Ag), copper (Cu), nickel (Ni), iron (Fe), aluminum (Al), stainless steel (SUS), or the like, but the present disclosure is not limited to as such. For instance, the conductive layer 24 can be formed by means of electroplating, coating, sputtering, chemical plating, electroless plating, or evaporation.


Furthermore, the recess 220 is free from being filled up by the conductive layer 24, so that the separation line L between two adjacent ones of the packaging modules 2a is still concave.


As shown in FIG. 2D-1, a singulation process is performed along a cutting path S shown in FIG. 2C-1 at each of the separation lines L to obtain a plurality of the electronic packages 2.


In an embodiment, based on the design of the recess 220 shown in FIG. 2B-1, side surfaces 23c of the encapsulation layer 23 are step-shaped. For instance, in the packaging module 2a, a notch P1 (or a recess) is formed on a portion of each of the side surfaces 23c of the encapsulation layer 23 adjacent to the second surface 23b, such that the conductive layer 24 is formed on the notches P1 (or the recesses), so that side surfaces 20c of the substrate structure 20 and a portion of each of the side surfaces 23c of the encapsulation layer 23 adjacent to the first surface 23a are exposed, i.e., the side surfaces 20c of the substrate structure 20 and a portion of each of the side surfaces 23c of the encapsulation layer 23 are not covered by the conductive layer 24.


Furthermore, the conductive layer 24 can also cover the side surfaces 20c of the substrate structure 20 and a portion of each of the side surfaces 23c of the encapsulation layer 23 adjacent to the first surface 23a, as shown in FIG. 2D-2. For instance, a singulation process can be performed along each of the separation lines L first, as shown in FIG. 2C-2, and then the conductive layer 24 is formed on the heat dissipation structure 25, the side surfaces 20c of the substrate structure 20, and the side surfaces 23c of the encapsulation layer 23.


It can be understood that if the manufacturing process shown in FIG. 2C-2 is continued, the conductive layer 24 can also only be formed on the heat dissipation structure 25 and a portion of each of the side surfaces 23c of the encapsulation layer 23 adjacent to the second surface 23b, as shown in FIG. 2D-3, so that the side surfaces 20c of the substrate structure 20 and a portion of each of the side surfaces 23c of the encapsulation layer 23 adjacent to the first surface 23a are exposed, and the conductive layer 24 is flush with the side surfaces 20c of the substrate structure 20 and the exposed side surfaces 23c of the encapsulation layer 23.


In addition, if the manufacturing process shown in FIG. 2B-2 is continued, that is, the recess 320 penetrates through the encapsulation layer 23 and the substrate structures 20, an electronic package 3 shown in FIG. 3A can be obtained, and the entire side surfaces 20c of the substrate structure 20 are flush with (or coplanar with) the entire side surfaces 23c of the encapsulation layer 23, so that the conductive layer 24 can be formed on the entire side surfaces 20c of the substrate structure 20 and the entire side surfaces 23c of the encapsulation layer 23. It can be understood that the conductive layer 24 can extend and be formed on a portion of each of the side surfaces 23c of the encapsulation layer 23 (as shown in FIG. 3B) or a portion of each of the side surfaces 20c of the substrate structure 20 (as shown in FIG. 3C) according to requirements.


Moreover, if the manufacturing process shown in FIG. 2B-3 is continued, that is, the recess 420 penetrates through the encapsulation layer 23 and free from penetrating through the substrate structures 20, an electronic package 4 shown in FIG. 4A can be obtained. In the electronic package 4, a notch P2 (or a recess) is formed on each of the entire side surfaces 23c of the encapsulation layer 23 and a portion of each of the side surfaces 20c of the substrate structure 20, such that the conductive layer 24 is formed on the notches P2 (or the recesses), and portions of the side surfaces 20c of the substrate structure 20 are exposed from the conductive layer 24. It can be understood that the conductive layer 24 can cover the entire side surfaces 20c of the substrate structure 20 (as shown in FIG. 4B); alternatively, the conductive layer 24 can also be flush with the exposed side surfaces 20c of the substrate structure 20 (as shown in FIG. 4C) according to requirements.


Therefore, in the manufacturing method of the present disclosure, the conductor 22a and the conductive layer 24 are in contact with each other to serve as a shielding structure to replace the conventional heat sink, so that the electronic component 21 can be protected from electromagnetic interference (EMI). Hence, compared with the prior art, the width of the wire of the conductor 22a of the present disclosure is much less than the width of the supporting leg of the conventional heat sink, so that the use area of the substrate structure 20 can be reduced so as to arrange other functional components when the electronic component 21 and the conductor 22a are disposed on the substrate structure 20, thereby achieving the purpose of integration and making the electronic products to meet the miniaturization requirements.


Furthermore, the conductive layer 24 can generate heat dissipation and shielding effects to the electronic component 21. Therefore, as shown in FIG. 7, an electronic package 7 is free from using the heat dissipation structure 25.

To sum up, in the electronic package of the present disclosure and manufacturing method thereof, the conventional heat sink is replaced by the conductor, and the width of the conductor is much less than the width of the supporting leg of the conventional heat sink.
