Abstract

There is herein described a process for fabricating GaAs FETs with an ion implanted channel layer wherein an ion implanted substrate is capless annealed under an arsine overpressure, and a relatively shallow portion of the outer surface of the substrate in the active layer is removed for the deposition of a gate metallic electrode.
