Abstract:
A method of forming a resist pattern comprising the steps of:forming a single-layer resist film by coating resist directly on a surface of a member to be processed, the resist containing a hydroxyl-group of a phenol compound capable of increasing volume by chemical reaction;exposing a portion of the resist film to energy beams;developing the coated resist film by removing either the exposed portion or unexposed portion of the resist film to form a pattern having an opening; andchemically reacting gas which comprises sulfonic acid halide or carboxylic acid halide with the hydroxyl-group of a phenol compound by contacting the gas with the hydroxyl-group of a phenol compound in the resist film to change the size of the opening of the resist film, the sulfonic acid halide or carboxylic acid halide being capable of increasing the volume of the resist film by chemical reaction with the hydroxyl-group of a phenol compound.
