  • Method concerning a junction barrier Schottky diode, such a diode and use thereof
    Patent number: 6524900
    Abstract: A method for controlling the temperature dependence of a junction barrier Schottky diode of a semiconductor material having an energy gap between the valence band and the conduction band exceeding 2 eV provides for doing this when producing the diode by adjusting the on-state resistance of the grid portion of the diode during the production for obtaining a temperature dependence of the operation of the diode adapted to the intended use thereof.
    Type: Grant
