A Two-Dimensional Subthreshold Current Model for Dual Material Gate SOI nMOSFETs with Asymmetric Halos

Abstract
A two-dimensional (2D) model for the subthreshold current in a dual-material gate silicon-on-insulator (SOI) MOSFET with a single halo is presented.The model considers a single halo doping in the channel near the source and a dual material gate to derive the channel potential using the explicit solution of the 2D Poisson’s equation.This,together with conventional drift-diffusion theory,results in the development of a subthreshold current model for the novel structure.Model verification is carried out using the 2D device simulator ISE.Good agreement is obtained between the model’s calculations and the simulated results.-
