| 20080217617 | Thin Film Transistor, Wiring Board and Methods of Manufacturing the Same - A gate electrode or a gate wiring of a thin-film transistor has a four-layer structure including an adhesive base layer, a catalyst layer, a wiring metal layer, and a wiring metal anti-diffusion layer which are laminated in this order. With this structure, adhesion and flatness are improved. In this case, the adhesive base layer is formed by a resin having a structure capable of coordinating to a metal. Hence, adhesion with an insulating substrate can be improved. Further, the wiring metal anti-diffusion layer is formed on the wiring metal layer, so that diffusion of a wiring metal can be inhibited. Thus, characteristics of the thin-film transistor can be improved. | 09-11-2008 |
