Patent JP-H01223772-A (JP)
Title: Manufacture of schottky gate field effect transistor
Inventor: ITO KAZUHIKO
IPC: H01L29/80
Filed: 1988-03-02
Abstract: PURPOSE:To make it possible to form a high impurity concentration area of a gate electrode and the source and drain in self-alignment by forming an insulation film containing an impurity such that a semiconductor layer is transformed into a conductor type identical to the conduction type, and by diffusing the impurity into the semiconduc tor layer by heat treatment and forming a gate electrode. CONSTITUTION:A n-type GaAs layer 2 is formed on a semiinsulating GaAs substrate 1 by ion implantation. Then, an SiO2 film 3 containing Sn is deposited, and an area where a Schottky junction is to be formed is opened by photolithography and etching. Then, heat treatment is performed. As a result of this, Sn contained in the SiO2 3 is diffused into the semiinsulating GaAs substrate 1, and an n<+> area 4 is formed. Furthermore, a gate electrode 5 is formed by photolithography, deposition and liftoff, then the gate electrode 5 can be formed with the n<+> region in self-alignment. The shape of the cross section of the gate electrode 5 can be made to a T-type cross section since the lower part is determined by the opening dimensions of the SiO2 film 3 but the upper part is arbitrarily checked by the photoresist dimensions at the time of the gate electrode liftoff. So when the length of a gate is made smaller, an increase in gate resistance can be suppressed.
