Abstract: A method of forming an organic thin film may include providing a substrate; providing an organic solution including an organic solute and a solvent having a boiling point of about 85° C. or less; dipping the substrate into the organic solution; removing the substrate from the organic solution; and/or precipitating the organic solute on the substrate to provide an organic thin film, wherein the removing the substrate from the organic solution is performed at a speed of about 10 to about 300 ?m/s from one end of the substrate to the other end of the substrate. Accordingly, an organic thin film having advantageous characteristics and a wide area may be obtained.

Abstract: A method for treating a polyimide surface which includes the steps of amine-treating the polyimide surface and drying the thusly amine-treated polyimide surface. The amine-treating step is preferably carried out by immersing the polyimide in an amine solution which includes an amine and a solvent. The amine is preferably an aliphatic, aromatic, or siloxane amine. The drying step is preferably carried out a temperature of about 50.degree.-200.degree. C. The polyimide is preferably a polyimide having at least one imide functional group in its main chain, and is most preferably a polycondensate of at least one dianhydride and at least one diamine.
