Abstract: Provided are a method of manufacturing multi-layered thin films, multi-layered thin films formed by the same, a method of manufacturing an organic thin film transistor including the same, and an organic thin film transistor manufactured by the same. The method of manufacturing multi-layered thin films includes: preparing a substrate; printing a blend solution including an organic semiconductor, an insulating polymer, and a solvent on the substrate; and simultaneously forming an insulating polymer thin film and an organic semiconductor thin film on the insulating polymer thin film by using a vertical phase separation phenomenon of the organic semiconductor and the insulating polymer, in which according to contents of the organic semiconductor and the insulating polymer in the blend solution and a printing speed of the blend solution, a width of the organic semiconductor thin film, and a thickness of the insulating polymer thin film are controlled.
