| Research Abstract |
The present research is concerned with a new technology for patterning process in fabricating thin film transistors (TFTs) used in liquid crystal display. Photolithography is conventionally used for this patterning process. However, a novel method are presented in this research projects, in which patterns are formed by press of a mold having 凹凸 patterns onto organic soft films laminated on substrates. By this method, low-cost pattern printing is attempted for TFT fabrication.
Actually, by using soft organic films such as polyethylene and polysthylene, TFTs with characteristics equivalent to those fabricated by the conventional photolithography can be successfully fabricated. Additionally, during this research, a new method, in which micron-size silicon integrated circuits are attached onto substrate just like a printing ink instead of making TFT, is proposed, and its feasibility is also successfully confirmed.
