Abstract

A method of fabricating a metal mask includes receiving a metal planar substrate and patterning the metal planar substrate. The metal planar substrate includes a first surface and a second surface opposite to the first surface. The patterning the metal planar substrate includes forming strip-shaped structures, forming through holes, and forming a blind hole in a direction from the first surface to the second surface. The through holes extend to the first surface and the second surface. The through holes and the strip-shaped structures are alternately arranged. The blind hole extends across the through holes.
