  • Patent number: 8703406
    Abstract: A method of forming a master from smaller originals is provided for use in replicating molecular transfer lithography (M×L) templates, cured polymer films for imprinting molds or cured polymer films for photonic applications. A coating layer on a base substrate is successively patterned in two or more areas using dissoluble conformal templates created from original master patterns, wherein areas not being patterned with a template at any given stage of the process are protected with photoresist and templates applied to open areas also partially overlap the resist-protected areas. Overlapping minimizes seam formation in the overall pattern. Templates have etch-resistant functional material that adheres to the coating layer on the base substrate. After dissolving the template to leave only the functional material in the pattern of the original master, etching of the coating layer transfers the pattern to the etched coating layer of the base substrate.
