Abstract

Hot-carrier-induced degradation in p-MOSFET's due to ac stress has been studied. Lifetimes under ac stress are calculated with a quasi-static model using parameters extracted from dc stress data. For inverter-like waveforms, the measurement data show reasonable agreement with the simulation results. For waveforms with turn-off transient occurring in the presence of high VD, more degradation than the model predicts is found if the transient is short (≤ 10 ns) and VG is high.
