Patent ID: 8551684

Claim:
A polymer for forming a resist protection film, the polymer being a compound represented by Formula 2 below: wherein R 1 is a hydrogen atom (H), a fluorine atom (F), a methyl group (—CH 3 ), a C1-C20 fluoroalkyl group, or a C1-C5 hydroxyalkyl group, R 2 is a C1-C10 linear or branched alkylene group or alkylidene group, or a C5-C10 cycloalkylene group or cycloalkylidene group, X is wherein n is an integer of 0 to 5 and * denotes the remaining moiety of Formula 2 after excluding X, and m, the stoichiometric coefficient of X, is 1 or 2, R 3 is a C1-C25 linear or branched alkyl group or a C5-C25 cycloalkyl group comprising at least one hydroxyl group (—OH) or carboxyl group (—COOH), p is an integer of 1 to 3, and a and b are the coefficients of their corresponding repeating units, wherein the amount of the repeating unit denoted by the coefficient a is in the range of 1 to 99% by weight based on the weight of the polymer, and the amount of the repeating unit denoted by the coefficient b is in the range of 1 to 99% by weight based on the weight of the polymer.
