Abstract
A semiconductor device includes a semiconductor body having opposing first and second surfaces in a vertical direction, a first semiconductor region of a first doping type electrically coupled to a first terminal, a second semiconductor region of a second doping type electrically coupled to a second terminal, and a third semiconductor region of the second doping type, but less highly doped than the second semiconductor region, extending in an active region of the semiconductor device from the first to the second semiconductor region in the vertical direction. A horizontal field-stop-region of the first doping type extends in an edge region of the device from the first semiconductor region into the semiconductor body in the vertical direction, such that it directly adjoins the first and second semiconductor regions. A horizontal compensation region of the first doping type extends from the horizontal field-stop-region into the second semiconductor region in a horizontal direction.
