Abstract:
1. A method of manufacturing a fine metal mask with an integrated metal substrate for support comprising the steps of: A. Providing a metal substrate by cutting an invar alloy or stainless steel plate to a desired size; B. Providing an fine mask b adding a photoresist layer on the metal substrate, exposing a desired pattern onto said photoresist layer, and electroforming a metal base layer and a metal layer with a low thermal expansion coefficient; C. Etching the metal substrate by etching out a pattern area of the metal substrate that corresponds to the pattern area of said fine mask using a chemical etching method to form a plurality of through holes, and creating an outer border area with a plurality of alignment through holes and internal separation area for support of said fine mask; and D. wherein said fine mask is integrated with said metal substrate; and said outer border and plurality of through holes are designed for fixing said fine mask to the surface of a substrate.
