Abstract
A method for forming a semiconductor device includes: forming, in a silicon carbide layer of a first conductivity type having a first side, a first silicon carbide region and a second silicon carbide region that forms a pn-junction with the first silicon carbide region; forming a contact region that forms an Ohmic contact with the second silicon carbide region; forming a barrier-layer on the contact region and the first silicon carbide region so that a Schottky-junction is formed between the barrier-layer and the first silicon carbide region and so that an Ohmic connection is formed between the barrier-layer and the contact region, the barrier-layer comprising molybdenum nitride; and forming a first metallization on the barrier-layer, and in Ohmic connection with the barrier-layer.
