摘要:
A semiconductor component having a semiconductor body is disclosed. In one embodiment, the semiconductor component includes a drift zone of a first conductivity type, a drift control zone composed of a semiconductor material which is arranged adjacent to the drift zone at least in places, a dielectric which is arranged between the drift zone and the drift control zone at least in places. A quotient of the net dopant charge of the drift control zone, in an area adjacent to the accumulation dielectric and the drift zone, divided by the area of the dielectric arranged between the drift control zone and the drift zone is less than the breakdown charge of the semiconductor material in the drift control zone.
