Method for fabricating organic thin film transistor in plastic base plate

Abstract

The method includes steps: providing a master-die and a plastic base plate, the master-die possesses a structure of relief printing plate; pressing out forming is carried out for the plastic base plate by the master-die so as to define position of source / drain poles on the plastic base plate; forming first pole layer, and forming source / drain poles on the position of source / drain poles; forming multiple semiconductor platforms, and each semiconductor platform covers a pair of source / drain poles; forming a second pole layer, which is above the semiconductor layer separated by the isolation layer; and forming a protection layer.

Description

technical field [0001] The invention provides a method for manufacturing an organic thin film transistor with a plastic substrate, especially a method for manufacturing an organic thin film transistor by defining the electrode positions of the plastic substrate by means of extrusion molding. Background technique [0002] In recent years, the widespread use of PCs and the popularization of the Internet have largely changed the traditional way of reading. However, due to people's reading habits, paper is still an important carrier for disseminating information. With the maturity of display technology, lighter, thinner, portable and flexible displays such as electronic paper have attracted the attention of many investors in the United States, and many large companies have also joined this "paper revolution". Organic thin-film transistors (OTFT) use organic molecular materials to develop thin-film transistors suitable for use in electronic products. When the panel is bent, the c...

Problems solved by technology

[0005] 1. The existing manufacturing methods of organic thin film transistors require complex and time-consuming steps, and the required material costs are also high, which increases manufacturing costs and affects market competitiveness

[0006] 2. The existing method of manufacturing organic thin film transistors must use yellow light technology, which is easy to cause wear and tear on the substrate and corrosion of chemicals, which affects the yield of the process

[0007] 3. The existing methods of manufacturing organic thin film transistors use glass substrates as substrates, which cannot improve the arrangement of organic semiconductor materials, thus affecting the electrical properties of organic thin film transistors.
