Abstract:
1. A method of fabricating a multi-die assembly, comprising: providing a substrate including a plurality of conductors; attaching at least one active face-down base die to the substrate in electrical communication with at least some of the plurality of conductors; providing a layer of epoxy adhesive to a back side of the at least one base die; placing a back side of at least one active face-up stack die on the layer of epoxy adhesive; curing the layer of epoxy adhesive and securing the back side of at least one stack die to the at least one base die; providing a direct electrical path between the at least one stack die and at least one of the plurality of conductors; securing at least another stack die to the assembly including securing the at least another stack die to the at least one stack die; electrically connecting the at least another stack die and at least one of the plurality of substrate conductors; securing at least one discrete component to at least one of the at least one stack die and the at least one base die; and extending a die-to-component bond wire between the at least another stack die and the at least one discrete component.
