Paper Abstract

Radiation damage to high-electron-mobility transistor (HEMT) structures, and its effect on electrical characteristics, are discussed. Radiation from cobalt 60 gamma and nuclear reactor sources was used on microwave and millimeter-wave monolithic circuits to determine total dose sensitivity. Heavy ions (15-MeV silicon) were used to evaluate other potential damage mechanisms. The dc and RF results for a 60-GHz-band monolithic microwave integrated circuit (MMIC) before and after irradiation are presented. The HEMT structures were found to be as resistant to radiation as previously tested metal-semiconductor field-effect transistors (MESFETs), and no new damage mechanisms were observed.
