Abstract:
1. A semiconductor device comprising: a semiconductor body comprising an inner region and an edge region; a first doped device region of a first doping type in the inner region and the edge region and coupled to a first terminal; at least one second doped device region of a second doping type complementary to the first doping type, in the inner region, and coupled to a second terminal; and a minority carrier converter structure in the edge region, the minority carrier converter structure comprising a first trap region of the second doping type adjoining the first doped device region, and a conductor electrically coupling the first trap region to the first doped device region, wherein the minority carrier converter structure further comprises a contact region of the first doping type and more highly doped than the first doped device region, wherein the contact region is connected to the conductor and adjoins the first doped device region.
