An adhesive/spacer structure (A,) is used to adhere first and second die () to one another at a chosen separation in a multiple-die semiconductor chip package (). The first and second die define a die bonding region () therebetween. The adhesive/spacer structure may comprise a plurality of spaced-apart adhesive/spacer islands (A) securing the first and second die to one another at a chosen separation (). The adhesive/spacer structure may also secure the first and second die to one another to occupy about 1-50% of the die bonding region.

Adhesive/spacer island structure for multiple die package

Adhesive/spacer structures used to adhere a first device, such as a die, or a package, to a second device 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 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 or so that the die attach side of the upper package faces away from the lower die or lower package substrate.

Individual pieces of film adhesive () are placed on a support surface (). Diced semiconductor chips () are individually placed on the individual pieces of the film adhesive thereby securing the diced semiconductor chips to the support surface to create first chip subassemblies (). The diced semiconductor chip and support surface of each of a plurality of the first chip subassemblies are electrically connected, such as by wires (), to create second chip subassemblies ((). At least a portion of at least some of the second chip subassemblies are encapsulated, such as with molding compound (), to create semiconductor chip packages ().
