Patent ID: 10615344

Abstract:
A vapor deposition mask used for forming a thin film pattern on a substrate enables to form much higher-definition thin film pattern and to closely attract and hold the vapor deposition mask to and on a surface of a transparent substrate by a magnetic force in a state that the substrate held on a substrate holder is intermediated therebetween, while preventing occurrence of shadow portions (vapor deposition shadows) to which no deposition material is adhered due to a holding member.A vapor deposition mask 1 is composed of a single resin film layer 2 or a resin film layer 2 and a holding member 7 of a substantially rectangular thin plate frame body, and a metal powder 4 is contained in the resin film layer 2 in which a plurality of through openings 3 are formed. When having the holding member 7, a single rectangular opening 8 including a portion of the resin film layer 2 where a plurality of the through openings 3 are formed is formed on the holding member 7.
