  • Abstract
    A simple but accurate threshold voltage model for deep-submicron MOSFET´s with nonuniform dopings is described in this paper. A simplified quasi-delta substrate doping profile is used to approximate the nonuniformity. We apply a hyperbola function to avoid the discontinuous problem at the boundary between different doping regions. By adjusting the parameter δ, the actual gradual doping profile can be obtained. The model developed is in good agreement with two-dimensional numerical simulation
