    • Disclosed is a method of manufacturing an organic semiconductor thin film for an organic thin film transistor from a blend of organic semiconductor/insulating polymer. The organic semiconductor thin film is configured such that organic semiconductor nanofibrils are dispersed in the form of a network in the insulating polymer layer. This organic semiconductor thin film is formed by dissolving the blend of organic semiconductor/insulating polymer in a marginal solvent of the organic semiconductor or mixed solvent thus preparing a blend solution, which is then applied while adjusting the solubility of the solution. An organic thin film transistor using the organic semiconductor thin film is also provided. The blend thin film of organic semiconductor/insulating polymer containing only about 3 wt% of the organic semiconductor exhibits electrical properties equal to those of a thin film composed exclusively of an organic semiconductor. The insulating polymer acts as a protective layer of the organic thin film transistor, thus obviating a need for forming the protective layer.
    • 公开了从有机半导体/绝缘聚合物的共混物制造有机薄膜晶体管的有机半导体薄膜的方法。 有机半导体薄膜被构造为使得有机半导体纳米原纤维以绝缘聚合物层中的网络的形式分散。 该有机半导体薄膜通过将有机半导体/绝缘聚合物的共混物溶解在有机半导体或混合溶剂的边缘溶剂中而形成,从而制备共混溶液,然后在调节溶液的溶解度的同时施加。 还提供了使用有机半导体薄膜的有机薄膜晶体管。 仅含有约3重量%有机半导体的有机半导体/绝缘聚合物的共混薄膜表现出与仅由有机半导体构成的薄膜的电性能相等的电性能。 绝缘聚合物作为有机薄膜晶体管的保护层,从而避免了形成保护层的需要。

    • 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.
    • 本发明涉及一种形成用于制造有机薄膜晶体管的多层薄膜的方法,更具体地,涉及一种使用垂直相分离同时形成有机半导体薄层和电介质薄层的方法,以及 使用该方法制造的高性能有机薄膜晶体管。 本发明的多层薄膜通过用有机半导体和具有不同表面能的绝缘聚合物的混合溶液涂布基板,然后垂直相分离所施加的混合溶液而形成。 多层薄膜包括形成在绝缘聚合物薄膜上的有机半导体薄膜。 包括根据本发明的多层薄膜的有机薄膜晶体管即使在使用少量的有机半导体时也能表现出优异的性能。 此外,由于绝缘聚合物薄膜可以用作有机薄膜晶体管的电介质层,因此不需要形成电介质层的过程,并且多层薄膜的下层的损伤发生在多层薄膜 通过溶液法形成薄膜,可以防止。
