Claim:
1. A semiconductor device, comprising: a semiconductor body with a front face and a back face, having an active zone located at the front face; a front surface metallization layer having a front face and a back face directed towards the active zone, the front surface metallization layer being provided on the front face of the semiconductor body and being electrically connected to the active zone; a first barrier layer, comprising amorphous molybdenum nitride, located between the active zone and the front surface metallization layer; and a second barrier layer, comprising amorphous molybdenum nitride, provided on the front face of the front surface metallization layer, wherein the first barrier layer contacts the front face of the semiconductor body or a contact at the front face of the semiconductor body at a first side of the first barrier layer and contacts the back face of the front surface metallization layer at a second side of the first barrier layer opposite the first side.
