RESIST COMPOSITION AND METHOD OF FORMING RESIST PATTERN
摘要:
A method of forming a resist pattern, including forming a resist film by coating a resist composition including a base component (A) that exhibits increased solubility in an alkali developing solution, a photo-base generator component (C) that generates a base upon exposure, an acid supply component (Z) and a compound (F) containing at least one selected from the group consisting of a fluorine atom and a silicon atom and containing no acid decomposable group which exhibits increased polarity by the action of acid on a substrate; subjecting the resist film to exposure baking the exposed resist film; and subjecting the resist film to alkali development, thereby forming a negative-tone resist pattern.
