Patent ID: 7880285

Claim:
A semiconductor device comprising: a semiconductor chip stack including at least one lower semiconductor chip as base of the semiconductor chip stack, and at least one upper semiconductor chip; an insulating intermediate plate arranged between the semiconductor chips, the insulating intermediate plate having a patterned structure on a top side and rear side thereof, and edge side faces thereof having conductor tracks that electrically connect the top and rear side patterned structures, wherein the intermediate plate is mounted directly on the lower semiconductor chip with an electrically conductive layer, and wherein the edge side faces of the intermediate plate project beyond edge side faces of the lower semiconductor chip; and connecting elements which electrically connect the semiconductor chips, the intermediate plate and external terminals to one another; wherein the semiconductor device has surface-mountable external contacts on its underside, and wherein the at least one lower semiconductor chip and the at least one upper semiconductor chip are electrically connected to one another via the conductor tracks of the edge side faces and the top and rear side patterned structures.
