Patent ID: 7371499

Claim:
A photoresist resin composition comprising: (A) about 10 to about 35% by weight of an acryl-based copolymer comprising as monomers about 5 to about 40% by weight of an unsaturated carboxylic acid, about 10 to about 70% by weight of an unsaturated compound containing an epoxy group, and about 10 to about 70% by weight of an unsaturated olefin-based compound, based on the total weight of the monomers, (B) about 5 to about 10% by weight of a quinone diazide compound, (C) about 55 to about 80% by weight of a solvent; and (D) about 0.01 to about 0.5% by weight of a silane-based surfactant represented by Chemical Formula (1): wherein R 1 represents an ethylene oxide group, R 2 represents a propylene oxide group, and X and Y represent integers of about 1 to about 20, and wherein the weights of each of the acryl-based copolymer, quinone diazide compound, solvent, and silane-based surfactant are based on the total weight of acryl-based copolymer, quinone diazide compound, solvent, and silane-based surfactant.
