Classification: G06F

Abstract:
A semiconductor modeling method comprising:a first step of storing data on an SiO2 layer; a second step of storm data on an Si layer formed so as to be in contact with the SiO2 layer; a third step of dividing the Si layer into a plurality of regions, and setting an amount of impurity contained in the respective regions; a fourth step of setting an inter-regional migration amount of the impurity contained in the respective regions for a unit of time; a fifth step of constituting an impurity pileup part in a vicinity of an interface between the SiO2 and the Si layer; and a sixth layer of calculating impurity distribution in the respective regions for every unit of time after completion of the first, second, third, fourth and fifth steps, the semiconductor modefling method being carried out without using diffusion equations.
