Threshold Voltage Roll-Off Due to Channel Length Reduction for a Nanoscale n-channel FinFET

Abstract: As the device feature size enters into the nanoscale, the modeling and simulation of short channel effects in FinFETs devices become challenging. In this paper an easy approach to model short channel effects threshold voltage roll-off in nanoscale n-channel FinFETs is presented. The decrease of threshold voltage with decrease in gate length is a well-known short channel effect called ...
