Abstract

The invention discloses an organic membrane transistor, which comprises a substrate, a grid electrode, an grid electrode insulating layer, an adhesive layer, a metal nano-particle layer and an organic semiconductor layer, wherein the grid electrode is arranged on the substrate; the grid electrode insulating layer is arranged on the grid electrode and the substrate; the adhesive layer is arranged on the grid electrode insulating layer and is provided with a hydrophobic surface above the corresponding grid electrode, as well as a first hydrophilic surface and a second hydrophilic surface on the two sides of the hydrophobic surface; a metal particle surface of the metal nano-particle layer is decorated with a hydrophilic group; the metal nano-particle layer is arranged on the first and second hydrophilic surfaces of the adhesive layer to be taken as a source electrode and a drain electrode respectively. In addition, the organic semiconductor layer is arranged on the hydrophobic surface of the adhesive layer as well as on the metal nano-particle layer.

Description

technical field [0001] The present invention relates to a thin film transistor and its manufacturing method, and in particular to an organic thin film transistor (OTFT) and its manufacturing method. Background technique [0002] The operation principle of the thin film transistor is similar to that of the traditional semiconductor MOS element, which is an element with three terminals (gate, drain, and source), and the function of the thin film transistor is used as a switching element of the pixel unit of the liquid crystal display. At present, the industry is actively developing an organic thin film transistor (OTFT), which has the advantages of low process temperature and low process cost compared with traditional thin film transistors, and combined with organic thin film transistor manufacturing technology on plastic substrates, it can be applied to active Drive displays, smart cards, or low-cost electronics.
