Abstract:
1. A semiconductor device comprising an MCM packaging structure, said MCM packaging structure comprising: a plurality of semiconductor chips; a circuit substrate having a substantially rectangular outer shape, wherein the plurality of semiconductor chips are juxtaposed on a semiconductor chip mounting surface of the circuit substrate, on which mounting surface the plurality of semiconductor chips are mounted; and a sealing resin that covers the semiconductor chip mounting surface and that extends along an outer edge of the circuit substrate and which completely encapsulates the plurality semiconductor chips so that the plurality of semiconductor chips are sealed within the resin, wherein a semiconductor chip of the plurality of semiconductor chips which is mounted so as to traverse a center line has a greater thickness in a direction perpendicular to the semiconductor chip mounting surface than a thickness, in the direction, of any of the other semiconductor chips of the plurality of semiconductor chips, said center line being defined by an intersection of (i) a longitudinal cross section which divides the semiconductor chip mounting surface into two in a longitudinal direction of the semiconductor chip mounting surface and (ii) a transverse cross section which divides the semiconductor chip mounting surface into two in a transverse direction of the semiconductor chip mounting surface.
