Abstract:
1. A semiconductor component having a semiconductor body comprising: a drift region of a semiconductor material in the semiconductor body; a drift control region composed of a semiconductor material, arranged, at least in sections, adjacent to the drift region in the semiconductor body, the drift control region being one of a first conduction type, a second conduction type complementary to the first conduction type, and intrinsic; an accumulation dielectric, arranged between the drift region and the drift control region; a body region; a drain region arranged at a distance from the body region, the drain region of the first conduction type; a source region of the first conduction type, the source region separated from the drift region by the body region; a gate electrode insulated from the semiconductor body by a gate dielectric, the gate electrode extending adjacent to the body region from the source region as far as the drift region; a first rectifier element coupling the drift control region to the source region; a doped connection region of the second conduction type, the doped connection region coupling the drift control region to the source region, and the doped connection region having a connection electrode; a further connection region of the first conduction type, the further connection region adjacent to the drift control region and doped more highly than the drift control region; and a second rectifier element, wherein the drift region is arranged between the body region and the drain region, wherein the first rectifier element is coupled between the connection electrode and the source region, and wherein the drift control region is coupled to the drain region via the further connection region and the second rectifier element.
