Provided is a blankmask with a light-shielding layer including a light block layer and an anti-reflective layer, and a hard mask film. The light block layer and the anti-reflective layer are formed by combining a layer formed of a MoSi compound and a layer formed of a MoTaSi compound. Thus, the blankmask enables formation of a pattern of 32 nm or less, since the light-shielding layer can be thinly formed to a thickness of 200 to 700 and a photomask having pattern fidelity corresponding to the resolution of the pattern can be formed. The light-shielding layer has an optical density of 2.0 to 4.0 at an exposure wavelength of 193 nm, chemical resistance, and a sufficient process margin for defect repair. Further, the hard mask film is formed to a thickness of 20 to 50 using a compound including tin (Sn) and chromium (Cr), thereby decreasing an etch rate of the hard mask film. Accordingly, a resist film can be formed as a thin film, thereby manufacturing a high-resolution blankmask.
