METHOD FOR PRODUCING FILM FORMATION MASK

摘要

The present invention is a method for producing a film formation mask having such a structure that a metal mask sheet (4) having multiple opening patterns formed thereon is stretched and fixed onto a frame-like metal frame (7), said method comprising: a first step of adhering the peripheral part of the metal mask sheet (4) to a mesh (1) which is made from a synthetic fiber and to which a certain tensile force is applied; a second step of cutting and removing a portion of the mesh (1) which corresponds to a film formation effective area that has a size enough to cover the multiple opening patterns formed on the metal mask sheet (4); a third step of bonding and fixing the frame (7) to the peripheral part of the metal mask sheet (4) from the opposite side of the mesh (1); and a fourth step of removing the mesh (1) from the metal mask sheet (4).
