Patent ID: 7915710

Claim:
A semiconductor device, comprising: a semiconductor substrate having an active surface; a conductive member in a via extending through the substrate; a metal pattern bonded to a second surface of the substrate opposite the active surface and connected directly to the conductive member; an electrically insulating adhesive layer between the metal pattern and the second surface of the substrate, the adhesive layer bonding the metal pattern to the substrate; a second substrate attached to the second surface of the substrate in a stack, wherein the second substrate includes a plurality of conductive features bonded to corresponding features of the metal pattern; and a third substrate attached to the active surface of the semiconductor substrate, wherein: the third substrate includes an active surface and a second surface opposite the active surface, a second metal pattern is bonded to the second surface of the third substrate, the third substrate being disposed between the second metal pattern and the substrate, and the active surface of the third substrate faces and is electrically connected to the active surface of the substrate.
