Method of forming vias in silicon carbide and resulting devices and circuits

Abstract:

A method of fabricating an integrated circuit on a silicon carbide substrate is disclosed that eliminates wire bonding that can otherwise cause undesired inductance. The method includes fabricating a semiconductor device including a Group III-V semiconductor layer on a surface on a silicon carbide substrate, wherein the semiconductor device defines at least one via through the silicon carbide substrate and the epitaxial layer.
