Abstract: A simplified method of fabricating V-groove junction field effect transistors using only two masking steps. The first masking step opens regions in an ohmic refractory metal layer deposited on a doped semiconductor wafer. V-grooves are anisotropically etched into the wafer through the openings, thereby defining source and drain regions and outer isolation V-grooves. The wafer is then coated with a passivating layer.

An ohmic contact to the back surface of the wafer forms the gate electrode. Multiple source and drain regions may be created between the outer isolation V-grooves and electrically parallel for a greater current rating.
