    • PURPOSE: A photoresist composition is provided to improve stability at room temperature, permeability, and adhesion to a silicon nitride film by including an acryl-based copolymer, an isocyanate group containing silane coupling agent, and a photosensitizer. CONSTITUTION: A photoresist composition includes 10-30 weight% of an acryl-based copolymer of an average molecular weight within 4000-9000, 0.1-2 weight% of a silane coupling agent containing an isocyanate group on the end, 1-15 weight% of a photosensitizer, and the remaining amount of a solvent. The acryl-based copolymer is prepared by polymerizing 15-30 parts by weight of unsaturated carboxylic acid or an anhydride of the same, 15-30 parts by weight of an epoxy group containing an unsaturated compound, and 40-70 parts by weight of an olefin-based unsaturated compound. The composition is used to form micropatterns on a substrate. A method of forming micropatterns includes a process for forming halftone on the silicon nitride film of the substrate.
