Patent ID: 7741723

Claim:
A semiconductor device comprising: a first chip which has a first element formed area, a first interconnection terminal connected to a circuit formed in said first element formed area, and a first external terminal connecting the circuit formed in said first element formed area to an exterior of the semiconductor device; a second chip which has a second element formed area, a second interconnection terminal connected to a circuit formed in said second element formed area, and a second external terminal connecting the circuit formed in said second element formed area to the exterior of the semiconductor device, and which is disposed to face said first chip via said second interconnection terminal connected to said first interconnection terminal, wherein said first and second external terminals are formed on surfaces of said first and second chips, the surfaces being on a same side of said first and second chips, wherein said first external terminal is formed on the surface facing said second chip and is connected to said second chip via a conductive connection member, wherein said second chip includes an internal joint terminal formed on the surface facing said first chip and connected to said conductive connection member, an external joint terminal formed on a surface opposite to the surface facing said first chip, and a first through hole electrically connecting said internal joint terminal and said external joint terminal, and wherein said first external terminal is connected to an outside of the semiconductor device via said external joint terminal.
