METHODS, SYSTEMS, AND ARTICLES FOR PRODUCING A FILM PATTERN ON A SUBSTRATE MATERIAL

Aspects herein are directed to systems, methods, and articles for producing a patterned film and using the patterned film to form a pattern of discrete overlay film structures on a substrate material. A uniform thickness of a film material is deposited on to a first surface of a run of carrier sheets, where each carrier sheet includes one or more holes extending there through. A first carrier sheet is extracted from the run of carrier sheets, and a second surface of the carrier sheet is positioned on a substrate material. Heat and/or pressure is applied to the film material to cause the film material to transfer to the substrate material through the one or more holes in the carrier sheet forming a pattern of discrete overlay film structures on the substrate material. The carrier sheet along with remaining portions of the film material is removed from the substrate material.
