Abstract
We have investigated RIE-induced damage in MOS devices with thermal oxide as well as N2O-annealed oxide as gate dielectrics. A systematic improvement in robustness against RIE-induced damage is seen when N2O flow rate and/or N2O anneal temperature are increased. We have demonstrated a N2O anneal process at 900°C, which provides a robust SiO2/Si interface against plasma damage and hot carrier stress
