Abstract

An analytical model is developed which accounts the quantum mechanical corrections to the threshold voltage V_T MOSFETs having their channel lengths in deep submicron region. The model is based on a variational solution of the Schrödinger equation for electrons in an inversion layer of a MOSFET, and it takes into account effects of the quantized electrons, the electron charge distribution and bandgap narrowing on V_T. Without any fitting parameters the model explains well the measured quantum shifts of V_T.
