    Abstract: Disclosed is a method of forming patterns including coating a metal-containing resist composition on a substrate; a heat treatment including drying and heating to form a metal-containing resist layer on the substrate; exposing a metal-containing resist layer using a patterned mask; and developing including coating a developer composition to remove unexposed regions to form a resist pattern, wherein the coating the metal-containing resist composition is performed by coating the metal-containing resist composition with a spin coater at a speed of about 100 to about 1,500 rpm for about 60 to about 120 seconds, the heating is performed at a temperature of about 90 to about 200° C. for about 30 to about 120 seconds, the exposing the metal-containing resist layer is performed by irradiating extreme ultraviolet light, light having a wavelength of about 5 nm to about 50 nm, or a combination thereof.

    Abstract: Provided is a method of forming patterns that includes coating a metal-containing resist composition on a substrate; coating a composition for removing edge beads along the edge of the substrate; drying and heating the coated resultant to form a metal-containing resist film on the substrate; and exposing and developing the dried and heated resultant to form a resist pattern,



    wherein the composition for removing edge beads may include at least one additive selected from a phosphorous acid-based compound, a hypophosphorous acid-based compound, a sulfurous acid-based compound and a hydroxamic acid-based compound, and an organic solvent.
