Claim 8:
9. A shape calculation method executed by a shape calculation device, the method comprising:
generating a first scattering profile obtained by irradiating a first structure on a substrate with an electromagnetic wave;
generating a second scattering profile calculated based on a second structure, the second structure being a structure simulated;
selecting at least a shape parameter, as a measuring target, from a plurality of shape parameters which define the second structure, and identifying factors of interest corresponding to the selected shape parameter among a plurality of factors from the second scattering profile, the plurality of factors being included in the second scattering profile and having information of scattered intensity;
creating a first data frame by extracting the factors of interest from the first scattering profile;
creating a second data frame by extracting the factors of interest from the second scattering profile;
fitting the first data frame and the second data frame; and
determining the shape of the first structure based on the fitting result.
