Aggressive downscaling of CMOS devices in every technology generation resulted in higher integration density and performance. At the same time, yield, which is the ratio of flawless versus all fabricated chips, drastically decreased. Failed chips are divided in defect devices (defect yield) and devices, which failed the desired performance (parametric yield). Parameter variations, which strongl...
