1.A more complete physical model of the device is adopted,and the sparse matrix technique of symbol Lu factorization,the self-adaptive finite element mesh refinement technique aed the modified nonlinear iteration technique are used in the numerical method. Thereby the speed of device analysis is increased con siderably.
