Abstract:
A semiconductor device includes a semiconductor body having a semiconductor substrate of a first conductivity type and a semiconductor layer of the first conductivity type on the substrate. A trench structure extends into the semiconductor body from a first surface and includes a gate electrode and at least one field electrode arranged between the gate electrode and a bottom side of the trench structure. A body region adjoins the trench structure and laterally extends from a transistor cell area into an edge termination area. A pn junction is between the body region and semiconductor layer. A doping concentration of at least one of the body region and semiconductor layer is lowered at a lateral end of the pn junction in the edge termination area compared to a doping concentration of the at least one of the body region and semiconductor layer at the pn junction in the transistor cell area.

Claim (Index 6):
The semiconductor device of  claim 1 , wherein the body region comprises:\n a first body sub-region extending from the transistor cell area into the edge termination area; and a second body sub-region in the edge termination area, wherein a maximum doping concentration of the second body sub-region is smaller than a maximum doping concentration of the first body sub-region.
