  • Abstract
    When the p-channel MOSFET is stressed near the maximum substrate current Isub, the lifetime t (5-percent increase in the transconductance) follows tI_{sub} = A(I_{sub}/I_{d})^{-n} , with n = 2.0. A simple electron trapping model is proposed to explain the observed power law relationship. The current ratio I_{sub}/I_{d} and the maximum channel electric field decrease with increasing stress time, which is consistent with electron trapping in the oxide during the stress.
