Abstract
PURPOSE: To obtain a mask by taking out resists, an insulating material and an inner plate after the resist statues were set on one side of the plate put in a frame, a connected part on the another side surface with a lead wire was covered by the insulating material and a metal coating was applied on.
CONSTITUTION: A plate 2 is put in a frame 1, and rolled patterns 3 being a desirable shape are made on one side surface by a resist. A lead wire 4 is attached on another side surface, and it is covered by the resist and then a metal film 6 is formed on it. After peeling off the resist pattern 3, the resist 5 and the plate 2 are solved out, and then the thin mask reinforced by the frame 1 is obtained. For example, a Ni coating is applied on a copper plate 2 and Ni frame 1 in Watt bath etc. By so doing, the thin metal mask film reinforced by the frame is obtained.
