Abstract
A charge compensation component having a drift path between two electrodes, an electrode and a counterelectrode, and methods for producing the same. The drift path has drift zones of a first conduction type and charge compensation zones of a complementary conduction type with respect to the first conduction type. A drift path layer doping comprising the volume integral of the doping locations of a horizontal drift path layer of the vertically extending drift path including the drift zone regions and charge compensation zone regions arranged in the drift path layer is greater in the vicinity of the electrodes than in the direction of the center of the drift path.
