We investigate how γ exposure impacts the hot-carrier degradation in deep submicron NMOSFET with different technologies and device geometries for the first time.The results show that hot-carrier degradations on irradiated devices are greater than those without irradiation,especially for narrow channel device.The reason is attributed to charge traps in STI,which then induce different electric field and impact ionization rates during hotcarrier stress.
