ORGANIC POLYMERIC SEMICONDUCTOR, METHOD FOR PREPARING THEREOF AND AMBIPOLAR ORGANIC THIN FILM TRANSISTOR USING THE SAME

摘要

An organic polymeric semiconductor, a manufacturing method of the same, and a bipolar organic thin film transistor using the same are provided to obtain high charge migration and to reduce leakage current by using an organic polymeric semiconductor material as an organic activation layer. A gate electrode(2) is formed on an upper surface of a substrate(1). A gate insulating layer(3) is formed on an upper surface of the gate electrode and the substrate. An organic activation layer(6) is formed on an upper surface of the gate insulating layer. Source/drain electrodes(4,5) are formed on both sides of the gate insulating layer. The organic activation layer is formed with an organic polymeric semiconductor layer. The organic activation layer is formed by using a screen printing method, a printing method, a spin coating method, a dipping method, and an ink injection method.
