Abstract

A semiconductor device comprises at least one semiconductor layer (4) of SiC and a layer (8) of a refractory metal nitride separated by an insulating layer (7) being at least next to the SiC layer of SiO2. The insulating layer comprises two sub layers, namely a first sub layer (9) of SiO2 next to the SiC layer and a second sub layer (10) of Si3N4 located between the first sub layer and the metal nitride layer.
