Semiconductor device with a charge carrier compensation structure in a semiconductor body and method for its production
Abstract:
A semiconductor device with a charge carrier compensation structure in a semiconductor body and to a method for its production. The semiconductor body includes drift zones of a first conduction type and charge compensation zones of a second conduction type complementing the first conduction type. The drift zones include a semiconductor material applied in epitaxial growth zones, wherein the epitaxial growth zones include an epitaxially grown semiconductor material which is non-doped to lightly doped. Towards the substrate, the epitaxial growth zones are provided with a first conduction type incorporated by ion implantation over the entire surface and with selectively introduced doping material zones of a second, complementary conduction type. Towards the front side, the epitaxial growth zones are provided with a second, complementary conduction type incorporated by ion implantation over the entire surface and with selectively introduced doping material zones of the first conduction type.
