Claim 14:
15. A power semiconductor device, comprising:
a semiconductor substrate having a first surface, the semiconductor substrate comprising a monocrystalline semiconductor material selected from a group consisting of SiC, GaN, AN and Ga2O3;
an insulation layer on the first surface of the semiconductor substrate, the insulation layer comprising a plurality of openings extending through the insulation layer; and
a front metallization on the insulation layer with the insulation layer being interposed between the front metallization and the first surface of the semiconductor substrate;
the front metallization extending through the respective openings of the insulation layer and forming respective metal connections arranged in the respective openings of the insulation layer, the metal connections forming respective electrical connections to the semiconductor substrate;
wherein the front metallization comprises one or more metals and/or metal alloys having a melting temperature higher than 1100° C.
