摘要

我们报道了pMOSFET由于负偏置温度不稳定性(NBTI)而退化的新效应-弛豫。在压力中断后,“明显”的NBTI退化减少(“恢复”)多达30-50%,这可以将设备寿命增加10-30倍。还讨论了退化随时间和应力电压外推的一些问题。

Transient effects and characterization methodology of negative bias temperature instability in pMOS transistors
We report a new effect - relaxation of pMOSFET degradation due to negative bias temperature instability (NBTI). "Apparent" NBTI degradation is reduced ("recovered") by as much as 30-50% after stress interruption, which can increase device lifetime by a factor of 10-30. Some problems associated with extrapolation of degradation with respect to time and stress voltage are also discussed.
