Patent number: 7785941Abstract: A method for fabricating a thin film transistor (TFT) is provided. A substrate having a gate, a dielectric layer, a channel layer and an ohmic contact layer formed thereon is provided. Next, a metal layer is formed over the substrate covering the ohmic contact layer. Next, the metal layer and the ohmic contact layer are simultaneously etched by a wet etching process to form a source/drain and expose the channel layer. Because the wet etching process can be used to selectively etch the ohmic contact layer, damage to the underlying channel layer may be negligible. Thus, the reliability of the device may be promoted. Furthermore, the process may be simplified, the production yield and the throughput of TFT may be increased.Type: GrantFiled: December 11, 2007Date of Patent: August 31, 2010Assignees: Taiwan TFT LCD Association, Chunghwa Picture Tubes, Ltd., Au Optronics Corporation, Hannstar Display Corporation, Chi Mei Optoelectronics Corporation, Industrial Technology Research Institute, TPO Display Corp.Inventors: Sai-Chang Liu, Cheng-Tzu Yang, Chien-Wei Wu
