Publication number: 20140216799Abstract: An object is to provide a conductive film forming method which can form a conductive film having low electric resistance on a base material by utilizing photo sintering even when the base material has low heat resistance. A conductive film forming method is a method in which a conductive film is formed on a base material, and the method includes the steps of forming a film composed of copper particulates on a base material, subjecting the film to photo sintering, and applying plating to the photo-sintered film. Whereby, it is possible to form a conductive film on a base material by lowering irradiation energy of light in photo sintering even when the base material has low heat resistance. Since the conductive film includes a plated layer, electric resistance decreases.Type: ApplicationFiled: August 13, 2012Publication date: August 7, 2014Applicants: APPLIED NANOTECH HOLDINGS, INC., ISHIHARA CHEMICAL CO., LTD.Inventors: Yuichi Kawato, Tomohiro Mito, Yusuke Maeda, Tomio Kudo
