Abstract
A semiconductor device includes a semiconductor body and an edge termination structure. The edge termination structure comprises a first oxide layer, a second oxide layer, a semiconductor mesa region between the first oxide layer and the second oxide layer, and a doped field region comprising a first section in the semiconductor mesa region, and a second section in a region below the semiconductor mesa region. The second section overlaps the first and the second oxide layers in the region below the semiconductor mesa region.
