  • Publication number: 20230045851
    Abstract: A method for producing a resist composition includes setting parameter, acquiring a pattern size for a regression analysis, analyzing performing a regression analysis, calculating a pattern size of a target resist composition based on the regression analysis, comparing the pattern size of the target resist composition and the target pattern size, determining a formulating amount of the resist composition in a case where a difference between the pattern size of the target resist composition and the target pattern size is within an allowable range, and producing a resist composition based on the determined formulating amount, in which, in a case where the difference is out of the allowable range, the method further includes changing at least the content of components in the target resist composition, and the formulating amount of the resist composition is determined based on the changed physical quantity to produce the resist composition.
