Abstract
Methods, systems, and devices are disclosed for thermal processing of silicon carbide semiconductor devices. In one aspect, a method for fabricating a silicon carbide semiconductor device includes forming a thin epitaxial layer of a nitrogen and phosphorous co-doped SiC material on a SiC epitaxial layer formed on a SiC substrate, and thermally growing an oxide layer to form an insulator material on the nitrogen and phosphorous co-doped SiC epitaxial layer, in which the thermally growing the oxide layer results in at least partially consuming the nitrogen and phosphorous co-doped SiC epitaxial layer in the oxide layer to produce an interface including nitrogen and phosphorous between the SiC epitaxial layer and the oxide layer.
