Abstract
An approximated analytical solution of Poisson's equation for the short-channel MOSFET opérating in the subthreshold regime is presented. It is shown that the proposed approach predicts a dependence of the threshold voltage on process parameters and drain and substrate voltages in very good agreement with two-dimensional analysis and with available experimental data. Finally, the method of this work, which permits to gain a factor of about 103 in CPU time with respect to numerical modeling for threshold predictions, seems particularly suited for statistical modeling.
