Abstract: A semiconductor device with a semiconductor body is specified, the semiconductor body extending in a vertical direction between a first main surface and a second main surface opposite the first main surface. The semiconductor body comprises a first semiconductor layer of a first conductivity type and a second semiconductor layer of a second conductivity type different from the first conductivity type thereby forming a first pn junction, wherein the first semiconductor layer is more heavily doped than the second semiconductor layer. A side surface of the semiconductor body extending between the first main surface and the second main surface delimits the semiconductor body in a lateral direction comprises a first partial region and a second partial region, wherein the first partial region and the second partial region delimit the first semiconductor layer in regions.

Abstract: A power semiconductor device includes a semiconductor wafer having a junction and a junction termination laterally surrounding the junction. A protection layer covers the lateral side of the semiconductor wafer and covers the second main side at least in an area of the junction termination. A first metal disk is arranged on the first main side to cover the first main side of the semiconductor wafer. An interface between the first metal disk and the semiconductor wafer is a free floating interface. A metal layer sandwiched between the first metal disk and the semiconductor wafer.
