Abstract: The effect of hot-carrier stress on 60 MeV proton irradiated thin gate oxide partially depleted SOI nMOSFETs has been studied. The results are compared with those from the electrical stress of non-irradiated devices. Whereas no significant differences are observed for the front channel degradation, hot-electron trapping in the buried oxide is found to be enhanced in the irradiated devices. This hot-electron trapping leads to a compensation or neutralization of the effects caused by the radiation-induced positive trapped charges. It is shown that a similar hot-electron trapping enhancement can be achieved in non-irradiated devices stressed under certain back gate bias conditions.
