摘要： A semiconductor device includes a first emitter region of a first conductivity type, a second emitter region of a second conductivity type complementary to the first type, a drift region of the second conductivity type, and a first electrode. The first and second emitter regions are arranged between the drift region and first electrode and each connected to the first electrode. A device cell of a cell region includes 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 is electrically connected to the source and body regions. A parasitic region of the first conductivity type is disposed outside the cell region and includes at least one section with charge carrier lifetime reduction means.
