摘要： In the liquid immersion lithography process, by simultaneously preventing deterioration of a resist film and deterioration of an immersion liquid employed during liquid immersion lithography which uses various immersion liquids, including water, resistance to post exposure delay of the resist film can be improved without increasing the number of processes, thereby making it possible to form a high resolution resist pattern using liquid immersion lithography. Using an alkaline soluble polymer, a crosslinking agent, and a solvent capable of dissolving them as at least constituent component, a composition is prepared and a protective film is formed on the surface of the resist film to be used, using the composition.
