Prediction of random dopant induced threshold voltage fluctuations in NanoCMOS transistors

The detailed analysis of a ground-breaking sample of 100,000 n-Channel MOSFETs, simulated with the Glasgow 3D device simulator, has allowed the distribution of random discrete dopant induced threshold voltage fluctuations to be constructed based on underlying physical processes. The construction may also be statistically enhanced, allowing a significant reduction in the computational effort necessary to accurately model random discrete dopant induced variability.
