Abstract: The melthod comprises the steps of applying a multi-layer photoresist on a GaAs wafer (101), reduction-transferring a shape of the upper layer of photoresist (109) to the intermediate layer of photoresist (107) and depositing an oxide film (108) transferring a shape of gate to the lower layer of photoresist (105), lateral-etching the photoresist (105) and depositing a tungsten silicide film (113); and forming a T type gate (114), a Si ion implant layer (115), an oxide film (117) and a metallic wire (118).
