摘要： A photoresist-composition includes about 4 to about 20 percent by weight of an acrylate copolymer; about 0.1 to about 0.5 percent by weight of a photoacid generator; and a solvent. The acrylate copolymer includes about 28 to about 38 percent by mole of a first repeating unit represented by Formula (1), about 28 to about 38 percent by mole of a second repeating unit represented by Formula (2), about 0.5 to about 22 percent by mole of a third repeating unit represented by Formula (3) and about 4 to about 42 percent by mole of a fourth repeating unit represented by Formula (4), wherein R1, R2, R3 and R4 independently represent a hydrogen atom or a C1-C3 alkyl group, X is a blocking group including an alkyl-substituted adamantane or an alkyl-substituted tricycloalkane, Y is a blocking group including a lactone, Z1 is a blocking group including a hydroxyl-substituted adamantane, and Z2 is a blocking group including an alkoxy-substituted adamantane.
