Blankmask and photomask using the same

Provided is a blankmask for a hardmask. In the blankmask, a hard film is formed by appropriately controlling contents of nitrogen and carbon therein to reduce a deviation in a critical dimension caused when an etch process is performed. A metal film is formed to a thin thickness by increasing a content of metal in a light-shielding film and reducing a content of metal in an anti-reflective film. Thus, resolution, pattern fidelity, and chemical resistance of the metal film may be improved. Also, the metal film and the hard film are formed such that a reflectivity contrast therebetween is high, thereby allowing the hard film to be easily inspected. Accordingly, the blank mask for a hardmask may be applied to a dynamic random access memory (DRAM), a flash memory, or a micro-processing unit (MPU) to have a half-pitch of 32 nm or less, and particularly, a critical dimension of 22 nm or less.
