Patent ID: 8637922

Claim:
A semiconductor device, comprising: a semiconductor body; in the semiconductor body, a source region, a body region, and a drift region with a first drift region section and a second drift region section, wherein the source region and the drift region are distant in a vertical direction of the semiconductor body, wherein the body region is arranged between the source region and the drift region, and wherein the second drift region section adjoins the first drift region section in the vertical direction of the semiconductor body; a gate electrode adjacent the body region and dielectrically insulated from the body region by a gate dielectric; a diode region of a semiconductor type complementary to the semiconductor type of the drift region, the diode region arranged in the drift region and spaced apart from the body region and the gate electrode by a portion of the drift region in the vertical direction of the semiconductor body; and a source electrode electrically connected to the source region, the body region and the diode region, wherein at least a first section of the source electrode is arranged in a trench extending adjacent the source region, the body region and a first section of the drift region to the diode region.
