Abstract:
1. An organic thin-film transistor, comprising: a substrate; a gate layer formed on said substrate; an insulator layer formed on said substrate by means of deposition or printing, said insulator layer being made of an organic material, an inorganic material or an organic-inorganic mixed material; a semiconductor layer formed on said insulator layer; a strip for defining a channel length formed on said semiconductor layer; an electrode layer formed on said semiconductor layer by screen printing, said electrode layer being a conductive paste or a conductive ink made of an organic material, an inorganic material or an organic-inorganic mixed material, said strip for defining channel length having a height of about one to two times a thickness of said conductive electrode layer; and a passivation layer coated on said electrode layer, whereby the organic thin-film transistor is formed with a top-contact/bottom-gate structure.
