Publication number: 20200058683Abstract: A wiring film capable of being patterned by a single etching process and has strong adhesion force to a resin substrate, and a semiconductor element and a display device that uses the wiring film, are disclosed. Since a base film that is in contact with a resin substrate is a copper thin film containing, at a predetermined ratio, aluminum as a main additive metal and silicon, titanium or nickel as a secondary additive metal, and has strong adhesion force to resins, wiring films (a gate electrode layer) do not separate from the resin substrate. Also, since the base film and a low resistance film contain a large amount of copper, the base film and the low resistance film may be etched together by means of an etchant or an etching gas by which copper is etched, therefore, the wiring films are able to be patterned by a single etching process.Type: ApplicationFiled: September 30, 2019Publication date: February 20, 2020Applicant: ULVAC, INC.Inventors: Satoru TAKASAWA, Yasuo NAKADAI, Junichi NITTA, Satoru ISHIBASHI
