An organic anti-reflective coating composition and a method for forming photoresist patterns using the same are disclosed which can prevent reflection of the lower film layer or substrate and reduce standing waves caused by light and variation of in the thickness of the photoresist itself, thereby, increasing uniformity of the photoresist pattern, with respect to a microfine pattern-forming process using photoresists for a photolithography by using ArF with 193 nm wavelength among processes for manufacturing semiconductor device. More particularly, an organic anti-reflective coating composition and a method for forming photoresist patterns using the same are disclosed which can obtain perpendicular photoresist patterns and thus inhibit breakdown and/or collapse of the patterns by comprising an acid-diffusion inhibitor.
