Abstract:
There are provided a vapor deposition mask capable of satisfying both high definition and lightweight in upsizing and forming a vapor deposition pattern with high definition while securing strength, a method for producing a vapor deposition mask and a vapor deposition mask preparation body capable of simply producing the vapor deposition mask, and furthermore, a method for producing an organic semiconductor element capable of producing an organic semiconductor element with high definition.
A metal mask 10 in which a plurality of slits 15 are provided and a resin mask 20 are stacked. Openings 25 required for composing a plurality of screens are provided in the resin mask 20. The openings 25 correspond to a pattern to be produced by vapor deposition. Each of the slits 15 is provided at a position of overlapping with an entirety of at least one screen.
