Abstract
PURPOSE:To facilitate precision control of threshold voltage and reduction of gate resistance by heat treating a gate metal, a lamination of a metal reactive with GaAs, a hard-to-react metal and easy-to-work metal, one over the other. CONSTITUTION:An electrically active layer 2B is formed on a semi-insulator GaAs crystal 2A. One of the metals, Pt, Ti. Pd reactive with GaAs a gate metal is vapor-deposited on the layer 2B. Then one of the metal Mo, Ta, W, Cr which are hard to react with GaAs is deposited. And again an easy-to-work metal, such as Au is deposited to form a gate of layered construction. It is then heat treated to make to the metal of the bottom layer react with GaAs to control threshold voltage to obtain the desired threshold voltage. A normally-off type GaAs FET made in this way has a low gate resistance.
