Abstract:
1. A semiconductor component comprising: a semiconductor body having a first and a second face, a first semiconductor zone of a first conductance type, at least one second semiconductor zone of a second conductance type, and a semiconductor junction formed therebetween running substantially parallel to the first face, an edge structure laterally adjacent to the second semiconductor zone and including at least one trench, the at least one trench extending in a vertical direction into the semiconductor body and being filled with a dielectric, the edge structure further including at least one third semiconductor zone of the second conductance type, which, at least partially, is adjacent to a face of the at least one trench which faces away from the first face, the edge structure further including a fourth semiconductor zone, which is more heavily doped than the first semiconductor zone, proximate to the first face; and a passivation layer supported on the first face at least in an area proximate to the edge structure, the passivation layer extending over the at least one trench.
