摘要:
The present invention relates to a method of forming a multilayered thin film used to manufacture an organic thin film transistor, and, more particularly, to a method of simultaneously forming an organic semiconductor thin layer and a dielectric thin layer using vertical phase separation, and a high-performance organic thin film transistor manufactured using the method. The multilayered thin film of the present invention is formed by coating a substrate with a mixed solution of an organic semiconductor and an insulating polymer having different surface energies and then vertically phase- separating the applied mixed solution. The multilayered thin film includes an organic semiconductor thin film formed on an insulating polymer thin film. The organic thin film transistor including the multilayered thin film according to the present invention can exhibit excellent performance even when a small amount of organic semiconductor is used. Further, since the insulating polymer thin film can be used as a dielectric layer of the organic thin film transistor, a process of forming the dielectric layer is not required, and the damage of a lower layer of the multilayered thin film, occurring when the multilayered thin film is formed through a solution process, can be prevented.
