Material for formation of protective film, method for formation of photoresist pattern, and solution for washing/removal of protective film

摘要

Disclosed are: a material for forming a protective film to be laminated on a photoresist film, which can prevent the contamination of an exposing device with an outgas generated from the photoresist film, which has little influence on the environment, which has a high water repellent property, which sparingly causes mixing with the photoresist film, and which can form a high-resolution photoresist pattern; a method for forming a photoresist pattern; and a solution for washing/removing a protective film. Specifically disclosed are: a material for forming a protective film, which comprises (a) a non-polar polymer and (b) a non-polar solvent; a method for forming a photoresist pattern by using the material; and a solution for washing/removing a protective film, which is intended to be used in the method.
