Abstract: A plastic ball grid array semiconductor package employs a metal heat spreader having supporting arms embedded in the molding cap, in which the embedded supporting arms are not directly affixed to the substrate or in which any supporting arm that is affixed to the substrate is affixed using a resilient material such as an elastomeric adhesive. Also, a process for forming the package includes steps of placing the heat spreader in a mold cavity, placing the substrate over the mold cavity such that the die support surface of the substrate contacts the supporting arms of the heat spreader, and injecting the molding material into the cavity to form the molding cap. The substrate is positioned in register over the mold cavity such that as the molding material hardens to form the mold cap the embedded heat spreader becomes fixed in the appropriate position in relation to the substrate.

Abstract: A multipackage module has multiple die of various types and having various functions and, in some embodiments, the module includes a digital processor, an analog device, and memory. A first die, having a comparatively large footprint, is mounted onto first die attach region on a surface of a first package substrate. A second die, having a significantly smaller footprint, is mounted upon the surface of the first die, on a second die attach region toward one edge of the first die. The first die is electrically connected by wire bonds to conductive traces in the die-attach side of the substrate. The second die is electrically connected by wire bonds to the first package substrate, and may additionally be electrically connected by wire bonds to the first die. In some embodiments a spacer is mounted upon the first die, on a spacer attach region of the surface of the first die that is not within the die attach region, and which may be generally near a margin of the first die.

Abstract: Adhesive/spacer structures used to adhere a first device, such as a die, or a package, to a second device such as a die, or a package, or a heat spreader, in a stacked semiconductor assembly, include a plurality of spaced-apart adhesive/spacer islands securing the first and the second devices to one another at a chosen separation. Either or both of the first and second devices can be a die; or, either or both of the devices can be a package. A package includes a die mounted onto and electrically interconnected to, a substrate, and where one package (an “upper” package) is stacked over either a lower die or a lower package, the upper package may be oriented either so that the die attach side of the upper package faces toward the lower die or lower package substrate (that is, the upper package may be inverted), or so that the die attach side of the upper package faces away from the lower die or lower package substrate.

Abstract: Stacked semiconductor assemblies in which a device such as a die, or a package, or a heat spreader is stacked over a first wire-bonded die. An adhesive/spacer structure is situated between the first wire-bonded die and the device stacked over it, and the device has an electrically non-conductive surface facing the first wire-bonded die. That is, the first die is mounted active side upward on a first substrate and is electrically interconnected to the substrate by wire bonding; an adhesive/spacer structure is formed upon the active side of the first die; and a device such as a die or a package or a heat spreader, having an electrically nonconductive side, is mounted upon the adhesive/spacer structure with the electrically nonconductive side facing the first wire bonded die. The side of the device facing the first wire bonded die may be made electrically nonconductive by having an electrically insulating layer, such as a dielectric film adhesive. Also, methods for making the assemblies are disclosed.
