Abstract:
A merged pn/Schottky semiconductor component with outer contacts as anode and cathode and a guard ring, and comprising alternately arranged Schottky junctions and pn junctions arranged near the surface of the semiconductor component, as well as low-doped drift zones of a semiconductor material that are arranged between the Schottky junctions and the pn junctions, and wherein the energy difference (Egapâˆ’&PHgr;barrier) between the band gap (Egap) in the electronic excitation range of the drift zone semiconductor material and the energetic height (&PHgr;barrier) of the Schottky barrier is at least 0.8 eV in the non-voltage state of the semiconductor component and the band gap (Egap) is higher than 1.5 eV.
