Patent ID: 7781877

Claim:
A device, comprising: a first subassembly and a second subassembly individually having a front side and a back side, the back sides of the first and second subassemblies facing each other, the first and second subassemblies individually having: an encapsulant material; a semiconductor die embedded in the encapsulant material, the semiconductor die having an active surface generally flush with the front side of the first or second subassembly and a back surface embedded in the encapsulant material; a conductive line on the front side of the individual first and second subassemblies and on the active surface of the semiconductor die; an adhesive material between and in direct contact with the encapsulant material at the back sides of the first and second subassemblies; and a conductive via that extends from the front side of the first subassembly, through the adhesive material, to the front side of the second subassembly, the conductive via being in direct contact with the conductive lines of both the first and second subassemblies.
