Abstract:
1. A semiconductor component, comprising: a semiconductor body of a first conductivity type, said semiconductor body having a first doping concentration greater than 5×10 at least a first electrode disposed on said first surface and at least a second electrode disposed on said second surface; a semiconductor zone of a second conductivity type opposite to the first conductivity type; a pn-junction formed between said semiconductor zone of the second conductivity type and said semiconductor body; at least one of said first and second electrodes being in contact with said semiconductor zone of the second conductivity type; semiconductor regions of the second conductivity type provided in said semiconductor body; said semiconductor regions being disposed at a respective distance from said semiconductor zone of the second conductivity type such that said semiconductor regions surround said semiconductor zone of the second conductivity type in a well-shape; each one of said semiconductor regions being interrupted at at least one location by channels formed by said semiconductor body, said channels electrically connecting parts of said semiconductor body separated by said semiconductor regions; and said semiconductor regions of the second conductivity type having a second doping concentration such that said semiconductor regions are not completely depleted of charge carriers in case of a reverse-biasing of said pn-junction.
