Bias temperature instability variation on SiON/Poly, HK/MG and trigate architectures

A summary of NBTI variation is reported on large data-sets across five generations of Intel technologies (90 nm to 22 nm) and a comparison of statistical frameworks is utilized to show the universality of variation metrics across generations. Large volumes of data and modeling are emphasized as critical to enable accurate simulations of NBTI in extreme tails.
