Patent number: 9625820Abstract: A method of patterning a thin film includes steps as follows. The thin film is formed. The thin film includes a plurality of first molecules, and each of the first molecules has a conjugated structure. A mask is covered on the thin film. The mask includes at least one exposing area, and the exposing area is correspondent to an illuminated region of the thin film. A solvent annealing and illuminating step is conducted, wherein the thin film covered by the mask is illuminated with a light source under an atmosphere of a first solvent, and a wavelength range of the light source is correspondent to an energy enabling the first molecules to reach an excited state. Thus a thickness of the illuminated region of the thin film is increased or decreased so as to form a pattern on the thin film.Type: GrantFiled: June 7, 2015Date of Patent: April 18, 2017Assignee: NATIONAL TSING HUA UNIVERSITYInventors: Arnold Chang-Mou Yang, Wei-Chun Chen

Publication number: 20090194408Abstract: The present invention provides a plasma method for conversion of carbon dioxide into useful organic products. In this method, carbon dioxide and counterpart molecules are mixed in a reaction chamber and the plasma excitation is utilized to trigger chemical reactions. Depending on the magnitude of the input power and molecular structures of counterparts, the final product may be polymers, oligomers, or low molecular weight small molecules. The conversion yields of carbon dioxide and chemical structures of the resulting products are strongly dependent on the selection of the counterpart molecules. Through this plasma technology, carbon dioxide is converted into useful materials such as plastics or fuels. This method is not only used to remedy global warming but also to produce new materials and energy.Type: ApplicationFiled: June 24, 2008Publication date: August 6, 2009Inventors: Arnold Chang-Mou Yang, Yi-Hsin Chang, Chun-Chih Chang
