Semiconductor device engineering — the neglected design importance of reducing variation

According to Scotten Jones

One really interesting point in this talk that was repeated at the Coventor event at IEDM was the importance of reducing variation. Device engineers focus on improving the mean but designers are more concerned with the distribution tails. Reducing variation is better even if the mean is lower! It was also noted that many of the proposed future devices will likely have more variability and therefore their actual performance may be less impressive than originally expected.
