Abstract:
1. A semiconductor device comprising: a semiconductor chip having a first main surface and a second main surface opposite to the first main surface; a heat dissipating plate opposed to the first main surface; a first surface electrode formed on the first main surface:, a first electrode disposed between the first main surface and the heat dissipating plate so as to be electrically connected to the first surface electrode of the semiconductor chip; a pressure contact member opposed to the second main surface; a second electrode disposed between the second main surface and the pressure contact member so as to be electrically connected to the semiconductor chip; and a pressure generating mechanism that generates a pressure for pressing the first electrode into contact with the heat dissipating plate and the semiconductor chip and pressing the second electrode into contact with the pressure contact member and the semiconductor chip, wherein the first electrode has a portion in contact with the first surface electrode and the first surface electrode has a portion in contact with the first electrode such that the portion of the first electrode has a higher surface roughness than the portion of the first surface electrode, and the first electrode has a lower hardness than the first surface electrode.
