C. %A Goldsman,N. %A Mayergoyz, Issak D %X A new numerical formulation for solving the hydrodynamic model of semiconductor devicesis presented. Themethod is based on using new variables to transform the conventional hydrodynamic equations into forms which facilitatenumerical evaluation with a block Gum- mel approach. To demonstrate the new method, we apply it to model a 0.35 wn 2-D LDD MOSFET, where robust convergence properties are observed. %B VLSI DESIGN %V 6 %P 191 - 195 %8 1998/// %G eng %N 1-4
