Abstract
A study was made to determine the susceptibility to failure of present commercially available GaAs FETs as a result of the concurrent exposure to temperature cycling, high relative humidity, and ionic contamination. Devices with Al and Au/refractory gates from four different suppliers were studied. Devices with Au/refractory gates were less susceptible to degradation as a result of the hostile environment. Failure mechanisms were determined and correlated with the electrical degradation of the devices.
