Patent ID: 7752579

Claim:
A computer-readable recording medium that stores therein a computer program for predicting film thickness of a thin film formed on a substrate using a film thickness function model expressing volume and height of the thin film, with a test substrate having wiring grooves of a predetermined shape, the computer program making a computer execute: receiving input of possible values for parameters included in a groove-shape function model expressing a shape of the wiring grooves after expansion and contraction of wiring grooves; computing model values to specify the shape of the wiring grooves after expansion and contraction by substituting the values received into the groove-shape function model; calculating the film thickness by substituting the model values and size data of the wiring grooves into the film thickness function model; calculating a difference between the calculated film thickness and film thickness obtained by measuring the film thickness; and determining optimal values for the parameters from among the possible values of the parameters based on the calculated difference.
