Abstract
An arrangement for use in a semiconductor component includes a semiconductor body and an edge structure. The semiconductor body having a first face, 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. The edge structure is laterally adjacent to the second semiconductor zone and includes at least a first trench. The first trench extends in a vertical direction into the semiconductor body and is filled with a dielectric material. The edge structure further includes a 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 includes a fourth semiconductor zone of the first conductance type, which is more heavily doped than the first semiconductor zone, and is proximate to the first face.
