A New Approach of Hot-Carrier Degradation and Lifetime Prediction for N-MOS Transistors

In this paper the degradation in the drain current and threshold voltage of the N-MOS transistors are observed by operating the device under stress voltage conditions. Using the observation results the effect of hot-carriers was investigated statistically and a new statistical method for modeling was proposed to be an alternative to those given in the literature. The observed and the estimated values of the degradation are compared
