Patent ID: 7184276

Claim:
A semiconductor device comprising: a plurality of semiconductor chips; and a plurality of substrates, each of the substrates including one of the semiconductor chips mounted thereon in a first region thereof, wherein: the substrates are stacked over top of each other; a first semiconductor chip mounted on a first stacked substrate is electrically connected to a second semiconductor chip mounted on a second stacked substrate through first terminals provided in a second region of each of the first and second stacked substrates outside the first region; a lowest substrate of the stacked substrates includes second terminals electrically connected to one of the semiconductor chips, the second terminals include external terminals on the lowest substrate of the stacked substrates, the external terminals projecting from a surface of the lowest substrate of the stacked substrates, the surface being opposite to that opposing another of the stacked substrates; and all of the second terminals are provided in a the first region of the lowest substrate to entirely overlap the semiconductor chip mounted on the lowest substrate of the stacked substrates.
