Abstract: A method of manufacturing a photo mask is provided to make a stable patterning process possible by improving precision of the process. A method of manufacturing a photo mask comprises the following steps of: measuring the critical dimension in accordance with each pattern in order to improve precision of a process; measuring line edge roughness(LER) of each pattern by a CD-SEM; extracting weight factors based on the critical dimension and line edge roughness and then sorting the weight factors correspondingly to line edge roughness according to the critical dimension; and applying the weight factors to adjust optical proximity correction modeling. The critical dimension is proportioned to a product of the line edge roughness and the weight factor. The weight factor is a factor indicating an important degree according to the line edge roughness of a dense line.
