Patent ID: 8643086

Claim:
A semiconductor component including a MOS transistor, comprising: a semiconductor body; a drift region of a semiconductor material in the semiconductor body; a drift control region composed of a semiconductor material, which is arranged, at least in sections, adjacent to the drift region in the semiconductor body and which is of a first conduction type, of a second conduction type complementary to the first conduction type, or which is intrinsic; an accumulation dielectric arranged between the drift region and the drift control region; a body region and a drain region arranged at a distance from the body region, between which the drift region is arranged, the drain region being of the first conduction type; a source region of a first conduction type which is separate from the drift region by the body region; a gate electrode, which is insulated from the semiconductor body by means of a gate dielectric and which extends adjacent to the body region from the source region as far as the drift region; a first rectifier element, via which the drift control region is coupled to the source region, a doped connection region of a second conduction type, via which the drift control region is coupled to the source region, the connection region having a connection electrode, and the first rectifier element being connected between the connection electrode and the source region; and a connection region of the first conduction type, which is adjacent to the drift control region and doped more highly than the drift control region, and a second rectifier element, the drift control region being coupled to the drain region via the connection region and the second rectifier element.
