Inventor: TOKUE TATSUO
IPC: H01L29/812
Filed: 1988-11-22
Abstract: PURPOSE:To make it possible to reduce parasitic capacitance and to improve microwave characteristics and reliability by etching an insulating film after the formation of a recess, evaporating a gate metal, and performing lift-off. CONSTITUTION:An insulating film 2 and a resist layer 3 are formed on a GaAs substrate 1. After the resist is patterned and an SiO2 film 3 are etched, the SiO2 film 2 forming a recess part 5 is etched. A gate metal (e.g., Ti-Al having a thickness of 200-5,000Angstrom ) is evaporated. Lift-off is performed, and a gate electrode 6 is formed. Thereafter, a passivation film 7 (e.g., an SiN film having a thickness of 500-1,000Angstrom  by a plasma CVD method) is formed. Therefore, the lower part of the eaves of the mushroom gate is not embedded with the film 7. To realize this structure, SiO2 etching before the formation of the gate need to be performed so that a part wider than the upper part of the electrode 6 is obtained. Accuracy is less required for etching width at this time than for etching width before the formation of the recess. Parasitic capacitance can be decreased with a spacer required for Schottky-property-damage prevention and the like being provided.
