Method for manufacturing mold for fine metal mask manufacturing and method for manufacturing fine metal mask

Abstract

Provided are a method for manufacturing a mold for manufacturing a fine metal mask and a method for manufacturing a fine metal mask, with which it is possible to obtain a mold capable of manufacturing a fine metal mask that can be permanently used, saves material costs, and improves productivity, and with which it is possible to manufacture a large-area fine metal mask, and with which it is possible to reduce a process defect rate, and to improve a yield. The method for manufacturing a mold for manufacturing a fine metal mask according to the present invention comprises the steps of: forming an insulating part corresponding to a slit shape of a fine metal mask on a manufacturing substrate; forming a conductive layer on the surface of the insulating part; forming a first metal layer on the manufacturing substrate by an electroforming plating process and separating to form a preliminary mold; and forming a second metal layer on the preliminary mold by an electroforming plating process and separating to form a fine metal mask manufacturing mold.

Description

technical field [0001] The present invention relates to a method for manufacturing a mold for manufacturing a fine metal mask and a method for manufacturing a fine metal mask, in particular to a mold capable of manufacturing a fine metal mask that can be permanently used, saves material costs, and improves productivity. And it is possible to manufacture a mold manufacturing method for fine metal mask manufacturing and a fine metal mask manufacturing method that can manufacture a large-area fine metal mask while reducing the process defect rate and improving the yield rate of the fine metal mask. Background technique [0002] Organic Light Emitting Diodes (OLED: Organic Light Emitting Diodes) components not only have the characteristics of realizing touch-sensitive screens, high-speed response speed, self-illumination, thin manufacturing, low power, and wide viewing angles, but flexible (Flexible) substrate Organic Light Emitting Diodes (OLED: Organic Light Emitting Diodes) c...

AI Technical Summary

Problems solved by technology

Such a fine metal mask is mainly used in the manufacture of small OLED display devices, but for the glass used to manufacture large-scale displays, the central part will sag toward the bottom when the size becomes larger, so the alignment with the fine metal mask is difficult. problems preventing the application of fine metal masks

[0006] Moreover, as the resolution gradually increases, the thickness of the fine metal mask should also be relatively thinner, but in the existing rolling process, there is a technical limit to thinning to more than a predetermined thickness

Recently, the manufacture of a fine metal mask using an electroforming plating process has been in progress, but it has not been commercialized due to various difficulties in the manufacturing process due to thinning of the thickness of the fine metal mask
