Description

    FIELD OF THE INVENTION
  • The present invention relates in general to semiconductor devices and, more particularly, to multi-chip semiconductor packages that have stacked dies.
  • BACKGROUND OF THE INVENTION
  • Semiconductors, or computer chips, are found in virtually every electrical product manufactured today. Chips are used not only in very sophisticated industrial and commercial electronic equipment, but also in many household and consumer items such as televisions, clothes washers and dryers, radios, and telephones. As products become smaller but more functional, there is a need to include more chips in the smaller products to perform the functionality. The reduction in size of cellular telephones is one example of how more and more capabilities are incorporated into smaller and smaller electronic products.
  • As the demand for semiconductor devices with low-cost, high performance, increased miniaturization, and greater packaging densities has increased, Multi-Chip Module (MCM) structures have been developed to meet the demand. MCM structures have a number of dies and other semiconductor components mounted within a single semiconductor package. The number of dies and other components can be mounted in a vertical manner, a lateral manner, or combinations thereof.
  • One such approach is to stack one die on top of another and then enclose the stack of dies in one package. The final package for a semiconductor with stacked dies is much smaller than would result if the dies were each packaged separately. In addition to providing a smaller size, stacked-die packages offer a number of advantages that relate to the manufacturing of the package, such as ease of handling and assembly.
  • In a stacked-die arrangement, the dies are wire-bonded sequentially, typically with automated wire-bonding equipment employing well-known thermal compression or ultrasonic wire-bonding techniques. During the wire-bonding process, the head of a wire-bonding apparatus applies a downward pressure on a conductive wire held in contact with a wire-bonding pad on the die to weld, or bond, the wire to the bonding pad on the die.
  • In many cases, stacked-die semiconductors can be fabricated faster and more cheaply than several semiconductors, each having a single die, which perform the same functions. A stacked-die approach is advantageous because of the increase in circuit density achieved.
  • A variety of semiconductor package configurations having stacked die arrangements are found in the art. However, the configurations currently known could stand to benefit from additional flexibility of implementing subcomponents such as integrated circuits (ICs) and integrated passive devices (IPDs) which can include resistors, capacitors, inductors, filters, and BALUNs. Accordingly, a need exists for a semiconductor package with such increased functionality. Additionally, a need exists for a semiconductor package which promotes higher performance while providing lower cost and a smaller footprint.

  • DETAILED DESCRIPTION OF THE DRAWINGS
  • The present invention is described in one or more embodiments in the following description with reference to the Figures, in which like numerals represent the same or similar elements. While the invention is described in terms of the best mode for achieving the invention's objectives, it will be appreciated by those skilled in the art that it is intended to cover alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims and their equivalents as supported by the following disclosure and drawings.
  • Current semiconductor packaging trends toward delivering towards low cost, smaller size, and higher performance. To help achieve lower cost and smaller size packages with higher performance, the chip scale module package (CSMP) has been implemented. The present invention utilizes the CSMP to incorporate the CSMP into a standard ball grid array (BGA) semiconductor package to provide increased functionality and a smaller package footprint.
  • Turning to FIG. 1 a, an example prior art “Known Good Unit” (KGU) flip chip CSMP package 10 is depicted. Package 10 includes a substrate which is connected to an integrated passive device (IPD). The IPD uses a solder interconnect to connect with an integrated semiconductor die.
  • Chip scale module packaging is an advanced system-in-package (SiP) which features a modular architecture that integrates mixed integrated circuit (IC) technologies and a wide variety of integrated passive devices such as resistors, capacitors, inductors, filters, BALUNs and interconnects directly onto the silicon substrate.
  • FIG. 1 b depicts an example prior art ball grid array (BGA) package 12. Package 12 includes a substrate with integrated metal circuitry connected to an array of solder balls. A die is wirebonded to the substrate, and enclosed with an encapsulant for protection.
  • FIG. 2 illustrates an example embodiment of a semiconductor package 14 according to the present invention. Package 14 incorporates a modified BGA package 12 with a modified KGU flip chip CSMP package 16. Package 16 can include either a land grid array (LGA) or a ball grid array (BGA) type configuration. Package 16 includes a flip chip die 18 which is incorporated into package 16 as shown. A first application die 20 such as an integrated circuit (IC) or an integrated passive device (IPD) as previously described is also incorporated into the package 16. An adhesive material 21 bonds a second application die 22 to the top surface of die 20 as depicted. Dies 20, 22 can be a combination IC/IC, IPD/IPD, or a combination of both IC/IPD. Moreover, additional application dies can be mounted to die 22 in any desired IC/IPD configuration to fulfill a specific need. An underfill material 24 is disposed between die 18 and die 20 to provide structural support.
  • Package 16 is attached on the BGA substrate 28 by a solder paste, flux, or adhesive material at bump pad 26. To provide connectivity, the application die 22 can use wirebond 30 to connect the wire bond pad 32 of die 22 with the BGA metal layer circuitry and/or bond fingers 34. Similarly, application die 22 can utilize wirebond 36 to connect the wire bond pad 38 to external bond pads and/or bond fingers 40 located on package 16. An encapsulant 42 is formed over package 16 to provide structural support to package 16 within overall package 14.
  • Package 14 can be constructed utilizing standard molding or TOP mold gate techniques. By combining CSMP package 16 and BGA package 12 into package 14, package 14 can take advantage of the positive aspects of each package to provide enhanced device functionality for applications such as wireless local area networks (WLAN), Bluetooth or similar application specific integrated circuits (ASIC), digital signal processing (DSP), memory applications, gate arrays, PC chipsets, and the like. In addition, package 14 can achieve passive function integration through the use of integrated passive devices (IPDs) which are incorporated on the CSMP module 16 without the use of a standard external passive component.
  • Turning to FIG. 3 a, an example embodiment of a semiconductor package 14 having an incorporated modified BGA package together with a modified KGU flip chip CSMP utilizing an additional external pad and bond finger configuration is illustrated. Package 14 includes components as illustrated in FIG. 2, such as flip chip die 18, first application die 20, second application die 22, underfill material 24, BGA substrate 28 with incorporated metal circuitry, wire bonding 30, 36 and bond pads 32, 34, 38, and 40. An encapsulant 42 is again disposed over the application dies 20, 22 to provide structural support.
  • In the depicted embodiment, interconnectivity from the flip chip CSMP external pads to pads located on the BGA substrate 28 is provided at junction 44 using solder paste or a conductive epoxy.
  • FIG. 3 b illustrates an example embodiment of a semiconductor package 14 having an incorporated modified BGA package together with a modified KGU flip chip CSMP in a ball grid array (BGA) configuration.

  • In the fifth step of the method, FIG. 4 f depicts the various wire bonding which provides interconnectivity between bond pads 32, 38 located as part of application die 22 and external bond pads/fingers 34, 40 on the CSMP package and BGA substrate as depicted. As a sixth step, the dies and wirebonding are overmolded with the encapsulant 42 as shown in FIG. 4 g.
  • In an additional embodiment, a modified KGU flip chip CSMP can be incorporated in a modified thermally-enhanced package for a particular application. For purposes of conception, FIG. 5 a again illustrates an example prior art “Known Good Unit” (KGU) flip chip chip scale module package (CSMP) 10 which is used in applications such as WLAN, Bluetooth, GPS, switches, and the like. FIG. 5 b refers to an example prior art thermally-enhanced semiconductor package 54 used in applications featuring application specific integrated circuits (ASICs), digital signal processing (DSP), microprocessors and controllers, chipsets, or other various applications requiring enhanced thermal performance.
  • FIG. 6 refers to a semiconductor package 56 having a thermally-enhanced substrate 57 which has been adapted for a modified KGU flip chip CSMP package 58. An IPD 60, or IC 60 is integrated into the CSMP package 58. The flip chip CSMP package 58 is attached to substrate 57. Substrate 57 includes a heat sink structure 70 and an integrated cavity 59, as well as metal circuitry incorporated into the substrate 57 to conduct electricity. Package 58 is attached in the cavity by an adhesive material or film 62 which can be thermal or conductive. A high thermal flip chip 64 is incorporated into package 56 as depicted and bonded to the cavity 59 using adhesive 62. An additional die 66, which can include an IC or additional IPD is mounted with adhesive 62 to die 60. Again, as before, dies 60, 66 can include any combination of IC/IC, IPD/IPD, IC/IPD, or IPD/IC. Additional dies (IC or IPD) can be mounted to the top surface of die 66 using a similar approach with adhesive 62. An underfill/encapsulant material 63 is utilized between dies 60, 64 to provide structural support. Similarly, an encapsulant or mold compound 68 is disposed over package 58 to provide structural support to dies 60, 66 within package 58 and the overall package 56.
  • Wire bonding can be incorporated into package 56 as follows. Wire bonds 72 provide electrical interconnectivity between bond pads 74 located on die 66 and bond pads 76 located as part of the modified thermally-enhanced package. Wire bonds 76 provide electrical connectivity between pads 80, also on die 66, and pads 82, located externally on CSMP package 58. Similarly, wire bonds 84 provide connectivity between pads 86 located as part of the modified thermally-enhanced substrate 57 and pads 88 located externally on modified CSMP package 58. Finally, solder balls 90 provide electrical connectivity to external electrical circuitry as depicted.
  • FIG. 7 a illustrates a first step in an example method of manufacturing a semiconductor package as illustrated in FIG. 6. A modified thermally-enhanced substrate 57 is provided, the substrate 57 having a heat sink 70 with an integrated cavity 59 again as shown to accommodate package 58. Film or adhesive material 62 is disposed on the thermally-enhanced substrate 57 as shown. In FIG. 7 b, a KGU flip chip CSMP 58 is attached to the material 62. As a next step, FIG. 7 c depicts underfill material 63 disposed between dies 60, 64. FIG. 7 d depicts the following step of applying a film/adhesive material 62 on the top surface of die 60, where FIG. 7 e shows die 66 attached to die 60 as a next step.
  • As a next step, the various wirebonding as previously described takes place as shown in FIG. 7 f. Package 58 with dies 60, 64 is then encapsulated/overmolded with encapsulant 68 as depicted in FIG. 7 g. As a next step, FIG. 7 h depicts solder balls 90 attached to the modified thermally-enhanced substrate 57 to provide connectivity to external circuitry.
  • In an additional embodiment, a “Known Good” wafer level chip scale package/chip scale module package (WLCSP-CSMP) can be modified to be incorporated into a modified ball grid array (BGA) package to perform specific functionality for a particular application. Again, for purposes of conceptual illustration, FIG. 8 a illustrates an example prior art “Known Good” wafer level chip scale package/chip scale module package 92 (WLCSP-CSMP). FIG. 8 b illustrates an example prior art ball grid array (BGA) package 12.
  • FIG. 9 illustrates an example embodiment of a semiconductor package 94 having an incorporated modified ball grid array (BGA) package 12 together with a modified KGU WLCSP-CSMP package. The WLCSP-CSMP is attached on the BGA substrate 28 by an adhesive material, solder paste, or flux-reflow material. An additional application die 98 is disposed at the backside of the IPD die 92 by using adhesive material 100. Additional dies 92 can be stacked on die 92 depending upon the application. Here, as before, dies 92 can include ICs, IPDs, or any combination thereof.
  • Connectivity of the modified WLCSP-CSMP to the BGA substrate 28 can be performed by wirebonds 102 connecting bond pads 104 located as part of die 98 to pads 106 connected to metal circuitry incorporated into BGA substrate 28. Additionally, junction 96 provides electrical connectivity between solder balls of the modified WLCSP-CSMP and additional pads 106 also connected to metal circuitry of the BGA substrate 28.
  • Package 94 can be constructed using standard molding or TOP mold gate techniques. The package 94 provides enhanced device functionality due to combining favorable aspects of the WLCSP-CSMP and BGA package designs for applications such as WLAN, Bluetooth, DSP, chipsets, and a host of related applications.
  • Package 94 adds passive function integration through the use of IPDs 98 as application dies 98 which are incorporated on the modified CSMP module as previously depicted without the requirement of using a standard external passive component.
  • In summary, the use of packages such as package 94, package 56, and package 14 provides enhanced functionality and serves to take advantage of positive aspects of older designs which are modified to create the packages 94, 56, and 14.
