  • Method of producing a microwave InP/SiO.sub.2 insulated gate field effect transistor
    Patent number: 4252580
    Abstract: An InP/SiO.sub.2 insulated gate field effect transistor which exhibits power gain at microwave frequencies is manufactured by using an n-type epitaxial semiconducting InP film on a semi-insulating InP substrate and depositing a pyrolytic silicon dioxide insulating film on the conducting InP film to form the gate insulator.
    Type: Grant
    Filed: May 21, 1979
    Date of Patent: February 24, 1981
    Inventor: Louis J. Messick
