VAPOR DEPOSITION MASK, VAPOR DEPOSITION MASK PREFORM, METHOD OF PRODUCING VAPOR DEPOSITION MASK AND METHOD OF PRODUCING ORGANIC SEMICONDUCTOR ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a vapor deposition mask which can achieve both high definition and weight saving even when being large-sized and enables formation of a high-definition vapor deposition pattern while keeping strength, a vapor deposition mask preform allowing easy production of the vapor deposition mask, a method of producing a vapor deposition mask and a method of producing an organic semiconductor element which enables production of a high-definition organic semiconductor element.SOLUTION: In a vapor deposition mask, a metal mask 10 provided with a silt 15 and a resin mask 20 in which an opening 25 corresponding to a pattern to be formed by vapor deposition is provided at a position superimposed on the slit 15 are laminated together, and the metal mask 10 has a general region 10a provided with the slit 15 and a thick region 10b thicker than the general region.
