Abstract
An improved MESFET integrated circuit device with a metal-semiconductor diode as the control element and a source and drain as other device elements is fabricated using a self-aligned gate process which consists of an implanted channel stopper underneath a thick field oxide, depletion and enhancement mode device channel implants, implanted source and drain regions, selective oxidation to form self-aligned gates, metal-semiconductor junctions as control elements, barrier metal and a thin film metallization system. The process and device structure are suited for high packing density, very low speed power product and ease of fabrication making it attractive for digital applications.
