Method of generating writing pattern, method of forming resist pattern, method of controlling exposure tool, and method of manufacturing semiconductor device

摘要

A method of generating a writing pattern is disclosed, which generates, from pattern data, writing pattern data to write a mask pattern in a photomask used in an exposure tool comprising a projection optical system to transfer the mask pattern to a resist film formed on a substrate, an immersion mechanism which forms a liquid film in a local region, and a movement mechanism which moves the substrate with respect to the projection optical system and the immersion mechanism, the method comprising obtaining a typical distribution of contact history values between the resist film and the liquid film in the unit exposure region, dividing a pattern which corresponds to the pattern data into a plurality of regions according to the typical distribution of the contact history values, and carrying out correction of a pattern included in each of the divided regions under a rule according to the contact history values.
