Abstract:
1. A semiconductor device comprising: a semiconductor element having a first surface and a second surface, the second surface being opposite the first surface in one direction; a first heat sink having a first heat radiation surface and a first end surface, the first end surface being opposite the first heat radiation surface in the one direction, the first end surface thermally and electrically coupled with the first surface of the semiconductor element; a second heat sink having a second heat radiation surface, a second end surface, and a depressed section, the second end surface being opposite the second heat radiation surface in the one direction, the second end surface surrounding the depressed section, the depressed section depressed toward the second heat radiation surface and having a bottom surface, the bottom surface thermally and electrically coupled with the second surface of the semiconductor element; and a resin member disposed in the depressed section and sealing the semiconductor element, the first heat sink, and the second heat sink in such a manner that the first heat radiation surface is exposed outside the resin member, wherein the depressed section of the second heat sink contains the entire first resin member.
