    摘要: A semiconductor diode is provided. The semiconductor diode includes a monocrystalline silicon semiconductor body including a first semiconductor region of a first conductivity type extending to a first surface of the semiconductor body and having a first maximum doping concentration, and a second semiconductor region of a second conductivity type forming a pn-junction with the first semiconductor region. The semiconductor diode further includes a polycrystalline silicon semiconductor region of the first conductivity type having a second maximum doping concentration which is higher than the first maximum doping concentration and adjoining the first semiconductor region on the first surface, a first metallization arranged on the polycrystalline silicon semiconductor region and in electric contact with the polycrystalline semiconductor region, and an edge-termination structure arranged next to the first semiconductor region. Further, a method for producing a semiconductor diode is provided.

    摘要: A semiconductor wafer for semiconductor components and to a method for its production is disclosed. In one embodiment, the semiconductor wafer includes a front side with an adjoining near-surface active zone as basic material for semiconductor component structures. The rear side of the semiconductor wafer is adjoined by a getter zone for gettering impurity atoms in the semiconductor wafer. The getter zone contains oxygen precipitates. In the near-surface active zone, atoms of doping material are located on lattice vacancies. The atoms of doping material have a higher diffusion coefficient that the oxygen atoms.
