Analysis of metal gate work-function variation for vertical nanoplate FET in 6-T SRAMs

Abstract

In this work, Work-Function Variation (WFV) are studied on 5 nm node gate-all-around (GAA) Vertical Nanoplate FET (NP VFET) in 6-T SRAM using Technology computer-aided design (TCAD) simulation. As WFV effects become intensified, we investigate the WFV effects for an accurate guideline with regard to grain size (GS) and channel area of NP VFET in SRAM bit cells.
