Using 3D simulations of statistical ensembles of unprecedented size, we have studied statistical threshold voltage variations induced by the combined effects of random dopants and line edge roughness in a state of the art 35 nm MOSFET. Statistical samples of 10<sup>5</sup> microscopically different transistors have been simulated. Based on careful statistical analysis of the simulation results we have developed statistical enhancement techniques, which deliver a high degree of statistical accuracy at a greatly reduced computational cost
