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.
