摘要：
A semiconductor device has a cell field with drift zones of a first type of conductivity and charge carrier compensation zones of a second type of conductivity complementary to the first type. An edge region which surrounds the cell field has a higher blocking strength than the cell field, the edge region having a near-surface area which is undoped to more weakly doped than the drift zones, and beneath the near-surface area at least one buried, vertically extending complementarily doped zone is positioned.
