Abstract
A generalized reliability model of BTI is presented where it is shown that gate stacks with similar interfacial layer lie on the same NBTI vs. E-field universal curve and those with similar bulk layer lie on the same PBTI vs. E-field universal curve. From these universal curves, an optimal gate stack can be derived for which NBTI=PBTI
