Abstract:
A method for forming a resist pattern, comprising the steps of: forming a resist film on a substrate by coating the substrate with a chemically amplified resist, the chemically amplified resist containing: a resin; and an acid generator that generates an acid when exposed to exposing radiation, the resin including a derivative of poly(vinyl alcohol), a derivative of a vinylamine polymer, a derivative of poly(N-hydroxyethylaziridine), a derivative of polyhydroxycyclohexene or a copolymer including at least one of these derivatives; exposing the resist film to exposing radiation with a wavelength of 160 nm or less; and forming the resist pattern with a line width of 0.1 .mu.m or less by developing the resist film exposed.
