Abstract :
In this paper we illustrate how by using advanced atomistic TCAD tools the interplay between long-range process variation and short-range statistical variability in FinFETs can be accurately modelled and simulated for the purposes of Design-Technology Co-Optimization (DTCO). The proposed statistical simulation and compact modelling methodology is demonstrated via a comprehensive evaluation of the impact of FinFET variability on SRAM cell stability.
