ABSTRACT:
The semiconductor device includes a first semiconductor region made from n-conducting SiC and a second semiconductor region made from p-conducting SiC. A Schottky contact layer electrically contacts the first semiconductor region, and an ohmic p-contact layer electrically contacts the second semiconductor region. Both contact layers consist of a nickel-aluminum material. This allows both contact layers to be annealed together without adversely effecting the Schottky contact behavior.
