Modeling of threshold voltage of a quadruple gate transistor

Md. Gaffar, Sayed Ashraf Mamuna, and Md. Abdul Matina

Available online 24 February 2011.

In this paper, a three dimensional analytical solution of electrostatic potential is presented for undoped (or lightly doped) quadruple gate MOSFET by solving 3-D Poisson's equation. It is shown that the threshold voltage predicted by the analytical solution is in close agreement with TCAD 3-D numerical simulation results. Numerical simulation, self-consistent Schrodinger–Poisson equations, calibrated by 2D non equilibrium green function simulation, are used.
