Classification: CPC H | IPC H

Claim 17:
18. A semiconductor device assembly comprising
a silicon core structure comprising:
a first side opposing a second side;
a via comprising a via surface that defines an opening extending through the silicon core structure from the first side to the second side; and
an oxide layer formed over all surfaces of the silicon core structure;

a conductive interconnection formed in the via and having a first surface exposed at the first side, a second surface exposed at the second side, and a third surface disposed between the first surface and the second surface;
an insulating layer disposed over the first side, the second side, and within the via, wherein the insulating layer is disposed between the third surface of the conductive interconnection and the silicon core structure; and
a heat sink coupled to first or second side of the silicon core structure, wherein the heat sink is disposed within a pocket formed in the insulating layer and coupled directly to the silicon core structure.
