Abstract
A mask manufacturing equipment includes a first stage on which a mask frame is disposed, the mask frame including cell openings arranged in a first direction and a second direction intersecting the first direction, a transfer module that places cell masks on the mask frame to respectively overlap the cell openings of the mask frame and the cell masks, a camera module that photographs the cell masks, a first processing module that irradiates a first laser beam between a border portion corresponding to a portion of the mask frame adjacent to an N-th cell opening and a first edge area of an N-th cell mask disposed on the border portion, and a second processing module that irradiates a second laser beam to a boundary area between the first edge area and a second edge area extending from the first edge area.
