Abstract:
A semiconductor device simulation method comprising:a first step of determining whether or not a silicide region made of a metal and silicon is in contact with a silicon region and a metal region; a second step of determining, if the silicide region is in contact with the silicon and metal regions, species diffusing through the silicide region according to a temperature heating the silicide, silicon, and metal regions and a composition of the silicide region; a third step of finding, if the species diffusing through the silicide region is silicon, positional relationships among the silicide, silicon, and metal regions according to a first diffusion equation expressing diffusion of silicon through the silicide region and geometry changing equations expressing geometric changes of the silicide, silicon, and metal regions; and a fourth step of finding, if the species diffusing through the silicide region is the metal, positional relationships among the silicide, silicon, and metal regions according to a second diffusion equation expressing diffusion of the metal through the silicide region and geometry changing so equations expressing geometric changes of the silicide, silicon, and metal regions.
