Publication number: 20110117695Abstract: This invention discloses a fabrication method of organic thin-film transistors (OTFTs) using the micro-contact printing. The OTFT can be of the bottom-gate or top-gate configuration. The micro-contact printing operation of this fabrication method does not require clean-room environment and high processing temperature, and does not have the problem of 2D shrinkage of the printed patterns either. Furthermore, the pre-wetting technique employed in the micro-contact printing results in improved fidelity in the pattern transfer and solves the problems of pairing and cross-talking between neighboring patterns.Type: ApplicationFiled: December 30, 2009Publication date: May 19, 2011Applicant: METAL INDUSTRIES RESEARCH & DEVELOPMENT CENTREInventors: Jung-Wei John Cheng, Chang-Pen Chen, Yeh-Min Lin, Chun-Yi Lee, Jeng-Rong Ho

Publication number: 20080169060Abstract: A method of fabricating carbon nanotube (CNT) pattern includes the following steps. First, one surface of a first transparent substrate is denoted as the first surface. A CNT thin film layer is coated on the first surface by a thin film deposition method. Then, a second substrate is disposed opposite to the first surface coated with a CNT thin film layer. By adopting a laser transfer method, a laser source irradiates on the CNT thin film layer coated on the fist surface, such that the CNT on the irradiated area explodes to depart from the first surface due to the high temperature resulted from the energy imparted by the laser light, so as to form a CNT pattern on the opposite second substrate.Type: ApplicationFiled: July 30, 2007Publication date: July 17, 2008Inventors: Jeng-Rong Ho, Jungwei John Cheng, Cheng-Kuo Sung, Shiang-Kuo Chang-Jian

Publication number: 20060165888Abstract: The present invention discloses a method of forming linear patterns, called “directional spin coating” technology. Parallel banks are formed on a substrate to define some trenches; the substrate is vertically erected on outer edge of a spin disc; and a liquid material is applied to the trenches, the spin disc is rotated, and with the centrifugal force of rotation, the material is uniformly coated on the substrate within individual trenches to form a linear pattern. The thickness of the formed pattern is similar to that achievable using the conventional spin-coating approach. The present invention can create linear patterns made of more than one material by selectively coating different materials on specific trenches.Type: ApplicationFiled: October 19, 2005Publication date: July 27, 2006Inventors: Jungwei Cheng, Jeng-Rong Ho
