Abstract
A semiconductor device includes a first semiconductor region including a first semiconductor material and a second semiconductor region adjoining the first semiconductor region, the second semiconductor region including a second semiconductor material different from the first semiconductor material. The semiconductor device further includes at least one of a drift zone and a base zone in the first semiconductor region, and at least one type of deep-level dopant in an emitter region of the second semiconductor region. The at least one type of deep-level dopant has a distance to the valence or conduction band of at least 100 meV.
