A Multi-Gate MOSFET Compact Model Featuring Independent-Gate Operation

Abstract

A compact model for multi-gate MOSFETs with two independently-biased gates is presented. The core model is verified against TCAD simulations without the use of any fitting parameters. Real device effects such as short channel effects and body doping effects are captured. The use of the model is demonstrated through two simulation examples: (1) Back-gate dynamic feedback of FinFET SRAM cells and (2) Tuning of device variations through back gate biasing.
