Web(b) A fraction of NBTI defects can be annealed once the stress is removed. This makes NBTI lifetimes (to reach a certain amount of degradation) higher for AC stress when compared to DC stress [20–23].

WebNMOS의 PBTI 보다는 PMOS의 NBTI 열화가 더 크기 때문에 NBTI 신뢰성이 주로 평가됨. PMOS에서 발생하는 Negative Bias Temperature Instability(NBTI) 현상은 중요한 신뢰성 문제 가운데 하나이지만 아직까지 NBTI의 물리적 특성은 완전히 이해되고 있지 않음. Web2.2 NBTI Modeling From experimental results, NBTI is seen to depend on the applied Vgs – with an ac-celeration factorγ, temperature – with activation energy Ea and has a time exponent n, around 0.15-0.2. Vth is taken as the degradation parameter ΔD_ NBTI. The degradation due to NBTI saturates after a given period of time and the amount
