    • An organic thin film transistor (OTFT), a method of manufacturing the same, and a biosensor using the OTFT are provided. The OTFT includes a gate electrode, a gate insulating layer, source and drain electrodes, and an organic semiconductor layer disposed on a substrate and further includes an interface layer formed between the gate insulating layer and the organic semiconductor layer by a sol-gel process. The gate insulating layer is formed of an organic polymer, and the interface layer is formed of an inorganic material. The OTFT employs the interface layer interposed between the gate insulating layer and the organic semiconductor layer so that the gate insulating layer can be protected from the exterior and adhesion of the gate insulating layer with the organic semiconductor layer can be improved, thereby increasing driving stability. Also, since the OTFT can use a plastic substrate, the manufacture of the OTFT is inexpensive so that the OTFT can be used as a disposable biosensor.
    • 提供有机薄膜晶体管(OTFT),其制造方法和使用OTFT的生物传感器。 OTFT包括栅极电极,栅极绝缘层,源极和漏极电极以及设置在基板上的有机半导体层,并且还包括通过溶胶 - 凝胶法在栅极绝缘层和有机半导体层之间形成的界面层。 栅绝缘层由有机聚合物形成,界面层由无机材料形成。 OTFT采用插入在栅极绝缘层和有机半导体层之间的界面层,从而可以保护栅极绝缘层免受外部的侵蚀,从而可以提高栅极绝缘层与有机半导体层的粘附性,从而提高驱动稳定性。 此外,由于OTFT可以使用塑料基板,OTFT的制造便宜,因此OTFT可以用作一次性生物传感器。
