Abstract

See full text

A power semiconductor device having a semiconductor body configured to conduct a load current is disclosed. In one example, the device includes a source region having dopants of a first conductivity type; a semiconductor channel region implemented in the semiconductor body and separating the source region from a remaining portion of the semiconductor body; a trench of a first trench type extending in the semiconductor body along an extension direction and being arranged adjacent to the semiconductor channel region, the trench of the first trench type including a control electrode that is insulated from the semiconductor body. The semiconductor body further comprises: a barrier region and a drift volume having at least a first drift region wherein the barrier region couples the first drift region with the semiconductor channel region.
