Title:
VAPOR DEPOSITION MASK MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2017036471
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vapor deposition mask manufacturing method capable of suppressing the occurrence of delamination between a first metal layer and a second metal layer forming a vapor deposition mask.SOLUTION: A vapor deposition mask manufacturing method according to the present invention comprises the steps of: preparing a substrate 51 on which a predetermined conductive pattern 52 is formed; forming, on the conductive pattern 52, a first metal layer 32 provided with a first opening 30 constituting a through-hole 25 by using a first plating solution; and forming, on the first metal layer 32, a second metal layer 37 provided with a second opening 35 constituting the through-hole 25 by using a second plating solution. The first plating solution contains a first primary brightener and a first secondary brightener, and the second plating solution contains a second primary brightener and a second secondary brightener. The concentration of the second secondary brightener in the second plating solution is lower than that of the first secondary brightener in the first plating solution.SELECTED DRAWING: Figure 4
