Title: Field-effect transistor
Inventor: TANAKA YUUJI
IPC: H01L21/338
Filed: 1989-08-30
Abstract: PURPOSE:To prevent the decrease in drain current due to the reduction of the width of a gate by providing a gate electrode through an insulating film which is provided on a semi-insulating GaAs substrate at the outer surface of an operating layer. CONSTITUTION:A photoresist film 3 is applied on an SiO2 film on a semi- insulating GaAs substrate 1. Patterning is performed, and Si ions are implanted. An N-type operating layer 5 is formed on the surface of the semi-insulating GaAs substrate 1. Then, the photoresist film 3 is removed. Thereafter, a photoresist film 6 is applied, and patterning is performed. The SiO2 film is removed, and an annular SiO2 film 2 is formed at the outer surface of the operating layer. Deposited tungsten silicide is etched away, and a gate electrode 7 and a pad 8 are formed. At this time, the gate electrode 7 is provided on the SiO2 film 2 at the boundary part between the operating layer and the semi- insulating GaAs substrate 1 and is not in direct contact with the semi-insulating GaAs substrate 1. Therefore, the deformation of the electrostatic potential at this part becomes less. Thus, the shift of the threshold voltage to the positive side due to the reduction of the gate width and the decrease in drain current can be prevented.
