On the threshold voltage shift after hot carrier injection in deep submicron n-channel MOSFETs: a quasi-uniform approach

Abstract Threshold voltage Vth instabilities observed in deep submicron n-MOSFETs after Hot Carrier Injection (HCI) are analyzed in details. A “quasi-uniform” approach for analyzing degradation effects is proposed along with a study of the “turn-over” phenomenon. Besides, the experimental Vth variation is accurately modeled.
