Abstract

Provided are a method of correcting a critical dimension (CD) in a photomask and a photomask having a corrected CD using the method. The method may include providing a substrate that is transparent with respect to an incident light, forming shielding patterns on the substrate to form a photomask, detecting a CD error region of the shielding patterns, and forming a correction film to vary an intensity of the incident light in the CD error region to correct critical dimensions (CDs) of circuit patterns formed by the shielding patterns.
