Abstract
A method of forming a pattern on a mask sheet using a laser beam includes determining a target scan line with respect to the mask sheet, which corresponds to a position of the pattern on a final mask sheet, determining a correction scan line with respect to the mask sheet, along which the laser beam is scanned to form the pattern of the final mask sheet, applying a counter force to the mask sheet, fixing the mask sheet onto a mask frame while the counter force is applied to the mask sheet, scanning the laser beam along the correction scan line, and releasing the counter force which is applied to the mask sheet.
