Abstract
A semiconductor device includes a semiconductor body comprising a first surface, a second surface opposite to the first surface, an active region, and an edge region surrounding the active region in a horizontal plane. The semiconductor device further includes a plurality of transistor cells at least partly integrated in the active region. Each transistor cell includes a drift region separated from a source region by a body region, and a gate electrode dielectrically insulated from the body region. The semiconductor device also includes a sensor device having a first sensor region of a first doping type integrated in the edge region. The first sensor region is electrically coupled to a first contact pad and to a second contact pad. Each contact pad is arranged either on the first surface or on the second surface. The sensor device at least partially extends around the active region.
