Abstract

A silicon carbide vertical MOSFET formed on a silicon carbide substrate with portions of epitaxial layers defining the various transistor electrodes, rather than defining the electrodes with implants and diffusion. An opening is formed in some of the epitaxial layers and a conductive layer is formed therein to electrically connect a drain contact on the rear of the substrate to the components on the front of the substrate.
