Abstract
A method of fabricating a self-aligned FET having a semi-insulating substrate of GaAs or InP with a conductive channel formed either by doping the surface or an epitaxially grown channel by molecular beam epitaxy or metalorganic vapor phase epitaxy in the substrate adjacent the surface. Forming a high temperature stable LaB.sub.6 /TiWN 'T-shaped' Schottky gate contact on the substrate surface, which is used for source and drain ohmic region implants into the substrate adjacent to the surface and self-aligned to the 'T-shaped' gate, with source and drain ohmic contacts also self-aligned with respect to the gate.
