Patent ID: 7759047

Claim:
A resist protective film composition for forming a protective film on a photoresist film, comprising: a polymer including a repeating unit having one or more groups selected from a carboxyl group and α-trifluoromethyl alcohol groups; one or more amine compounds selected from the group consisting of tertiary amine compounds having fluoroalkyl groups represented by the following general formula (2): N(X 10 ) n1 (Y 10 ) 3-n1 (2) wherein: n1 is 1, 2, or 3; X 10 may be the same or different, X 10 contains at least one or more fluorine atoms, and X 10 is represented by any one of the following general formulae (X 10 )−1 to (X 10 )−3: wherein: R 300 , R 302 , and R 305 independently represent a linear or branched alkylene group having 1-4 carbon atoms, which may contain —O—; R 301 and R 304 independently represent a linear, branched or cyclic alkyl group having 1-30 carbon atoms, which may contain a hydroxy group or an ester group, and hydrogen atoms of the alkyl group may be totally or partially substituted with a fluorine atom; R 303 represents a single bond or a linear or branched alkylene group having 1-4 carbon atoms; and R 306 represents a linear, branched or cyclic alkyl group having 1-30 carbon atoms, and hydrogen atoms of the alkyl group may be totally or partially substituted with a fluorine atom; and Y 10 may be the same or different, Y 10 represents a linear, branched, or cyclic alkyl group having 1-30 carbon atoms, and Y 10 may be linked to each other to form a ring, and the ring may contain —O—; and a solvent that does not dissolve the photoresist film, which is an underlying layer of a resist protective film; wherein the resist protective film composition forms the resist protective film on a photoresist film.
