Method of manufacturing a frame integrated with a resin layer metal mask

To provide a method of manufacturing an organic semiconductor device can be manufactured method for manufacturing a deposition mask that can satisfy both the even when large high definition and light weight, and a high-definition organic semiconductor element . On one surface of A metal plate and preparing a resin layer-metal plate resin layer is provided, with respect to the metal plate in the resin layer with a metal plate, a slit which penetrates only the metal plate forming a metal mask with a resin layer by forming, then the resin by the metal mask side is irradiated with a laser from which a plurality of rows formed in a matrix openings corresponding to the pattern of deposition produced on the resin layer forming a mask, to produce a vapor deposition mask from. .FIELD 1
