Irradiation effects on the electrical characteristics under high field
stress of nitrided and non-nitrided very thin silicon oxide films are
studied. The generation of new electron traps during constant current
stress is increased for irradiated samples. This enhancement is more
significant for pure silicon dioxide when compared to nitrided oxide.
Further, the correlation between charge to breakdown and traps generat
ion rate during constant current injection is verified and remains val
id after irradiation. (C) 1997 Elsevier Science Ltd.
