Abstract:
PURPOSE: An organic thin film transistor and a manufacturing method thereof are provided to simplify a process by forming a polymer insulating film with different material properties due to a one-time spin coating. CONSTITUTION: An organic insulating film(40) is formed on a substrate(10). A gate electrode(50) is formed near the organic insulating film. An active layer is symmetrical with the gate electrode while interposing the organic insulting film. A source/drain electrode(20) is located on both sides of the gate electrode. The organic insulating film comprises a diblock copolymer which forms a lamella structure.

PURPOSE: A method for locally crystallizing organic thin film and a method for improving organic thin film transistor using the same are provided to locally improve the crystallinity of an organic layer by performing thermal process. CONSTITUTION: An organic layer(150) is formed on a substrate(110). An organic solvent(S) is applied on a specific area(150a) for improving crystallinity. The organic solvent gradually is evaporated. The movement of particles of the organic layer is activated in the area spread by the organic solvent. The crystallinity of the area spread by the organic solvent is locally improved through self-alignment.

Abstract:
PURPOSE: A metal pattern formation method and an apparatus using the same are provided to improve electrical properties of a metal wire by forming the metal wire using a non-electrode electrochemical plating method. CONSTITUTION: An adhesive pattern is formed on a substrate(S10). An initiator is combined on the adhesive pattern by spraying an initiator solution on the substrate(S20). A metal is combined with the initiator by performing a plating process after spraying a metal precursor solution on the substrate(S30). The initiator solution and the metal precursor solution on the substrate are eliminated between the adhesive patterns by performing a cleaning process(S40).
