Abstract

A two-dimensional (2D) model for the subthreshold current in the dual-material gate (DMG) silicon-on-insulator (SOI) MOSFET with a single halo is presented. The model considers 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. Together with the conventional drift-diffusion theory, this results in the development of a subthreshold current model for the novel structure. Model verification is carried out using the 2D device simulator ISE. Excellent agreement is obtained between the calculations and the simulated results of the model.

Key words： dual-material gate (DMG); silicon-on-insulator (SOI); electron mobility
