Abstract:A model for effective channel doping in submicron LDD nMOSFET's is presented by adding the effect of the lateral nonuniform pile-up charge centroid to the Gaussian profile with peak doping near the edge of the metallurgical channel. The effect of the pile-up centroid on the threshold voltage parameter extraction is elaborated, from which semi-empirical relationships on all fitting parameters are formulated. Threshold voltage versus gate length data from MEDICI-simulated devices with lateral Gaussian pile-up doping profiles are used for the verification of this model.
