Abstract

A method of producing a semiconductor device includes etching a recessed aperture in a substrate, forming a gate electrode in the aperture, burying the gate electrode with resist, etching the resist to expose the gate electrode, depositing a high conductivity metal on the gate electrode, and forming ohmic electrodes on opposite sides of the gate electrode by a series of processing steps.
