  • Patent number: 7560783
    Abstract: The present invention relates to a metal-semiconductor contact comprising a semiconductor layer and comprising a metallization applied to the semiconductor layer, a high dopant concentration being introduced into the semiconductor layer such that a non-reactive metal-semiconductor contact is formed between the metallization and the semiconductor layer. The metallization and/or the semiconductor layer are formed in such a way that only a fraction of the introduced doping concentration is electrically active, and a semiconductor layer doped only with this fraction of the doping concentration only forms a Schottky contact when contact is made with the metallization. Furthermore, the invention relates to a semiconductor component comprising a drain zone, body zones embedded therein and source zones again embedded therein. The semiconductor component has metal-semiconductor contacts in which the contacts made contact only with the source zones but not with the body zones.

  • Patent number: 7492208
    Abstract: The invention relates to a MOSFET circuit having reduced output voltage oscillations, in which a smaller CoolMOS transistor (T2) with a zener diode (Z1) connected upstream of its gate is located in parallel with a larger CoolMOS transistor (T1), so that, during a switch-off operation, after the larger transistor has been switched off, the smaller transistor (T2) carries a tail current on account of the zener voltage still present, which tail current attenuates output oscillations of the voltage.
