Abstract
A self-aligned gate field effect transistor is described which is capable of operating at high frequencies. A method for making the transistor is described which comprises plating metal partially over an oxide layer, then removing the oxide to produce an overlapping metal portion and then plating again to produce a gate contact between the overlapping metal portions.
