Abstract

A substrate inspection system includes an imaging unit provided in a substrate processing apparatus and configured to acquire image data by imaging a surface of a substrate for color information on which a film is formed; a film thickness measurement unit provided in the substrate processing apparatus and configured to measure a film thickness of a substrate for film thickness measurement on which a film is formed under same conditions as on the substrate for color information; and a model creation unit configured to create a film thickness model corresponding to a correlation between information about color change on the surface of the substrate for color information caused by forming the film, which is acquired based on the image data, and the film thickness of the substrate for film thickness measurement, which is measured by the film thickness measurement unit.
