Abstract:
1. A method for producing a radiation detector comprising a semiconductor body with a first base zone of a first conduction type and with at least one second base zone arranged at least partly in the first base zone, extends in a vertical direction of the semiconductor body and is doped complementarily to the first base zone, wherein the method comprises: providing a semiconductor substrate; producing several contiguous epitaxial layers arranged one above another on the semiconductor substrate, each layer comprising a basic doping of the first conduction type and together with the semiconductor substrate form the semiconductor body; and producing semiconductor zones of a second conduction type, complementary to the first conduction type, in the epitaxial layers in such a way that the complementarily doped semiconductor zones are adjacent to one another in a vertical direction and thus form the at least one second base zone.
