Patent ID: 8532972

Claim:
A method of simulating a manufacturing process of a structure which comprises a plurality of adjacent components, the method comprising causing a computer to perform operations of: importing mesh data and material data which are set for each of components; specifying, as a calculation target region, a region in a first component in which impurities are to be diffused among the components, the specified calculation target region being a part of the structure; setting, other than the components of the structure, a virtual film of a desired thickness in contact with the specified calculation target region, the material of the virtual film being the same as the material of a second component in contact with the specified calculation target region; setting boundary conditions at interface between the specified calculation target region and the virtual film on the basis of the material data; incorporating the boundary conditions into a diffusion equations to solve the diffusion equations of the specified calculation target region and the virtual film; and bringing data on the concentration of impurities of the specified calculation target region obtained by the calculation into data on the structure before the specification of the calculation target region.
