PROBLEM TO BE SOLVED: To improve convergence of solution, speed up analysis, and reduce operation time, in the region of a basic equation where nonlinearity is intense. SOLUTION: In the course of calculation using a Newton repetition method, in the numerial analysis of a semiconductor device by using a computer, when the electric field change amountδΨi in a high electric field region (|Ei+1 ,1|>Elim ) exceeds the upper limit valueδΨi , damper is applied to the potential change amountδΨi , and repetition calculation is executed.
