Abstract
Ultra short channel MOS transistors with high permittivity gate dielectrics suffer from carrier quantum confinement in the channel and from electric field fringing in the dielectric layer. This paper deals with the 2D numerical simulation of the coupling between these two physical mechanisms. We shall demonstrate how they impact the threshold parameters in MOS transistors for metallurgical channel lengths ranging from 5 to 50 nanometers. A special attention has been paid to the control on numerical errors.
