  • Patent number: 6753132
    Abstract: A resist film is formed by applying, on a substrate, a pattern formation material containing a polymer including a first unit represented by Chemical Formula 1 and a second unit represented by Chemical Formula 2, and an acid generator: Chemical Formula 1: Chemical Formula 2:  wherein R1 and R2 are the same or different and selected from the group consisting of an alkyl group, a chlorine atom and an alkyl group including a fluorine atom; R3 is a protecting group released by an acid; and m is an integer of 0 through 5. Subsequently, the resist film is irradiated with exposing light of a wavelength shorter than a 180 nm band for pattern exposure, and a resist pattern is formed by developing the resist film after the pattern exposure.
