Abstract
In this paper, we present, the results of a study of time dependent dielectric breakdown (TDDB) of ultra-thin gate oxide (<40 Å) for a wide range of oxide fields 4.3<Eox<9 MV/cm at high temperatures. In addition, we report on an anomaly that we observed in the I-V of MOS devices when a negative voltage sweep is applied to the gate while the other terminals (substrate and active area) are grounded
