Abstract:
A method of forming a resist pattern including: forming a resist film on a substrate using a chemically amplified negative resist composition; forming a latent image of a first line and space pattern by subjecting the resist film to first exposure through a photomask; forming a latent image of a second line and space pattern so as to intersect with the latent image of the first line and space pattern by subjecting the resist film to second exposure through a photomask; and subjecting the resist film to developing to form a hole pattern in the resist film.
