Abstract:
1. A method for manufacturing a vapor deposition mask suitable for forming vapor deposit films in the manufacture of electronic devices, the method comprising: (a) forming a photosensitive film on an electroconductive film disposed on a surface of a transparent plate or a transparent film, the electroconductive film having a mask pattern therein; (b) exposing portions of the photosensitive film through openings in the mask pattern of the electroconductive film; (c) removing unexposed portions of the photosensitive film such that the exposed portions of the photosensitive film remain in the openings in the mask pattern of the electroconductive film; (d) forming a metal plating layer on the electroconductive film such that the exposed portions of the photosensitive film create a mask pattern in the metal plating layer; and (e) separating the metal plating layer from the electroconductive film to form the vapor deposition mask, wherein the mask pattern in the vapor deposition mask is suitable for forming vapor deposit films in the manufacture of electronic devices.
