Patent ID: 8860132

Claim:
A semiconductor device arrangement comprising a semiconductor device, the semiconductor device comprising: a source region, a drain region, a body region, and a drift region, the drift region arranged between the body region and the drain region and the body region arranged between the source region and the drift region in a semiconductor body; a gate electrode adjacent the body region and dielectrically insulated from the body region by a gate dielectric; a drift control region adjacent the drift region and dielectrically insulated from the drift region by a drift control region dielectric; an injection region of a doping type complementary to the doping type of the drain region, the entire injection region being arranged on an opposite side of the drift control region dielectric as the drift control region; a drain electrode adjoining the drain region; and an injection control region of the same doping type as the drain region but more lowly doped, wherein the injection control region adjoins the drift control region dielectric, extends in a first direction along the drift control region, and adjoins the drain region in the first direction and the injection region in a second direction different from the first direction.
