摘要：
The degradation of p-MOS transistors is shown to proceed logarithmically in time. A simple, analytic degradation model is proposed that fully accounts for this observation. The logarithmic time dependence originates from the logarithmic growth of a region of filled traps from the drain junction towards the source. On this basis, a reliable lifetime extrapolation is performed.
