Abstract:
A method of forming a resist pattern, including: a step (1) in which a resist film is formed 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; a step (2) in which the resist film is subjected to exposure; a step (3) in which baking is conducted after the step (2); and a step (4) in which the resist film is subjected to an alkali development, thereby forming a negative-tone resist pattern, and a resist composition used in the step (1).
