See full text

A photoresist composition includes from about 20% to about 50% by weight of a polymer, from about 0.5% to about 1.5% by weight of a photo-acid generator, from about 0.01% to about 0.5% by weight of a photo absorber and the remainder includes an organic solvent. Also provided is a method of forming a fine pattern including forming a thin film on a substrate; forming a photoresist pattern by using a photoresist composition that includes from about 20% to about 50% by weight of a polymer, from about 0.5% to about 1.5% by weight of a photo-acid generator, from about 0.01% to about 0.5% by weight of a photo absorber and a remainder comprising an organic solvent; and patterning the thin film by using the photoresist pattern as an etch-stop layer to form a fine pattern.
