Abstract:
A method for manufacturing a LIGA process mask, said method comprising:a step of forming a plating seed layer on a substrate; a step of forming a plating-resistant layer made of a substance that resists plating disposed upon said plating seed layer; a step of forming a layer of resist material disposed upon said plating-resistant layer; a step of patterning said resist layer to form a patterned resist layer, and using said patterned resist layer to pattern said plating-resistant layer so as to form a plating pattern disposed upon said plating seed layer; a step of plating inside of said plating pattern so as to form a plated layer on said plating seed layer; and a step of removing said resist layer, said plating-resistant layer and a non-plated part of said plating seed layer.
