Abstract
A method of forming a thin film pattern includes: providing a printing roller and a substrate including a thin film; coating the printing roller with an etch-resist solution including a base polymer, a carrier solvent, a tackifier and a surfactant; removing the carrier solvent from the coated etch-resist solution thereby transitioning the etch-resist solution from liquid phase to solid phase; patterning the solid etch-resist; transferring the patterned etch-resist from the printing roller to the substrate; and patterning the thin film corresponding to the transferred etch-resist.
