    IPC: C23C16/04

    CPC classification number: C23C16/042

    Abstract: A manufacturing method of a mask assembly includes tensioning a mask sheet, connecting the tensioned mask sheet with a mask frame, and defining opening processing areas in the tensioned mask sheet to form openings respectively corresponding to the opening processing areas. The defining of the opening processing areas includes defining initial opening processing areas in the tensioned mask sheet in a first direction and in a second direction crossing the first direction to determine a processing sequence of the initial opening processing areas, calculating cumulative deformation amounts accumulated in each of the initial opening processing areas based on the processing sequence, and correcting a size and a position of each of the initial opening processing areas based on the cumulative deformation amounts.
