摘要： A material for protective film formation that is used to form an upper-layer protective film for a resist film and that contains at least a polymer component soluble in water or alkali and an alcohol containing a fluorine atom; and a method of forming a resist pattern with the use of the same. Consequently, not only can the degeneration of resist film during liquid immersion exposure by various liquids for liquid immersion exposure, for example, water and the degeneration of liquid immersion exposure liquids per se be simultaneously prevented in the liquid immersion exposure process, but also without inviting an increase of the number of processing steps, the resistance to post exposure delay of the resist film can be enhanced.

摘要： The formation of high-resolution resist patterns by liquid immersion lithography with various fluids is enabled by protecting a resist film from deterioration (such as bridging) during the immersion exposure in a fluid (such as water) and the fluid from deterioration and improving the stability of a resist film in the storage after exposure without increase in the number of treatment steps. A material for forming resist protection films which comprises an alkali-soluble polymer for forming a protective overcoat for a resist film, characterized in that the contact angle of the polymer to water is 90° or above. The polymer is preferably an acrylic polymer which comprises as the essential components constituent units derived from (meth) acrylic acid and constituent units derived from a specific acrylic ester.
