  • Publication number: 20130001554
    Abstract: An example embodiment relates to a method of manufacturing an array of electric devices that includes attaching a platform including a micro-channel structure to a substrate. The method includes injecting first and second solutions into the micro-channel structure to form at least three liquid film columns, where the first and second solutions include different solvent composition ratios and the liquid columns each, respectfully, include different solvent composition ratios. The method further includes detaching the platform the substrate, removing solvent from the liquid film columns to form thin film columns, and treating the thin film columns under different conditions along a length direction of the thin film columns. The solvent is removed from the thin film columns and the thin film columns are treated under different conditions along a length direction of the thin film columns.
