An organic thin-film transistor and a method for manufacturing the same are described. The method forms a gate layer on a substrate, an insulator layer on the substrate, forming a semiconductor layer on the insulator layer, and a strip for defining a channel length on the semiconductor layer. An electrode layer is screen printed on the semiconductor layer, and a passivation layer is coated on the electrode layer. The organic thin-film transistor manufactured by the method of the invention has a substrate, a gate layer formed on the substrate, an insulator layer formed on the substrate, a semiconductor layer formed on the insulator layer, a strip for defining a channel length formed on the semiconductor layer, an electrode layer screen-printed on the semiconductor layer, and a passivation layer coated on the electrode layer. Thereby, an organic thin-film transistor with a top-contact/bottom-gate structure is obtained.

Organic thin-film transistor and method for manufacturing the same

An organic semiconductor element having multi protection layers and process of making the same are provided. Firstly, forming a first protection layer on the thin film transistor. Next, forming a second protection layer which is thick enough to serve as the photo spacers on said first protection layer. The multi protection layers are then grown on said organic thin film transistor, so as to enable the second protection layer to have the additional function of the photo spacers by the patterning process. Thus the organic thin film transistor can be prevented from being damaged, and achieving the simplification of the manufacturing process and the reduction of the production cost.
