Assignee: INFINEON TECHNOLOGIES AG
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A power semiconductor device, comprising:
a semiconductor substrate comprising a wide bandgap semiconductor material and a first surface;
an insulation layer above the first surface of the semiconductor substrate, the insulation layer comprising at least one opening extending through the insulation layer in a vertical direction;
a front metallization above the insulation layer with the insulation layer being interposed between the front metallization and the first surface of the semiconductor substrate; and
a metal connection arranged in the opening of the insulation layer and electrically conductively connecting the front metallization with the semiconductor substrate;
wherein the front metallization comprises at least one layer that is a metal or a metal alloy having a higher melting temperature than an intrinsic temperature of the wide bandgap semiconductor material of the semiconductor substrate.
