Claim:
1. A semiconductor device, comprising: a first emitter region of a first conductivity type, a second emitter region of a second conductivity type complementary to the first conductivity type, and a drift region of the second conductivity type arranged in a semiconductor body; a first electrode, wherein the first emitter region and the second emitter region are arranged between the drift region and the first electrode and are each connected to the first electrode; a cell region comprising at least one device cell, the at least one device cell comprising a body region of the first conductivity type adjoining the drift region, a source region of the second conductivity type adjoining the body region, and a gate electrode adjacent the body region and dielectrically insulated from the body region by a gate dielectric; a second electrode electrically connected to the source region and the body region of the at least one device cell; at least one first parasitic region of the first conductivity type that is floating and disposed outside the cell region; a plurality of device cells; and a floating semiconductor region of the first conductivity type in the cell region between the individual device cells, wherein the at least one first parasitic region is connected to the floating semiconductor region.
