Variability study of silicon nanowire FETs

Abstract

In this work, impact of device variability for silicon nanowire FETs is assessed and SRAM design implication is presented based on 3-D numerical simulation. Both the conventional and junctionless nanowire FETs are shown to be sensitive to structural variation whereas the former is more tolerable. Both the circular wire and non-circular wire cases for feasible SRAM design with a focus on read noise margin are included in our study.
