Patent ID: 7696615

Claim:
A semiconductor device comprising a semiconductor chip, wherein the semiconductor chip comprises: a first chip substrate having a first surface and a second surface that are opposite to each other; a second chip substrate adjacent to the first chip substrate, the second chip substrate having a first surface, a second surface opposite the first surface, and a side that is in contact with a side of the first chip substrate; a pillar-shaped terminal penetrating through the second chip substrate from the first surface of the second chip substrate to the second surface of the second chip substrate; and a pad-shaped terminal disposed on the first surface of the second chip substrate, wherein the second surfaces of the first and second chip substrates are substantially coplanar and the pillar-shaped terminal has a contact surface that is substantially coplanar with the second surface of the second chip substrate, and wherein the first chip substrate includes a semiconductor material and the second chip substrate includes an insulating material.
