PRODUCING METHOD OF METAL WIRES

摘要

PURPOSE: A producing method of a metal wire is provided to manufacture a metal wire at a low cost and to be easily applicable to a large-sized substrate without using a vacuum film-forming device. CONSTITUTION: A photosensitive underlying resin film(2) is formed on an insulating substrate(1) by a coating method. Exposure and development onto the underlying resin film are performed to obtain an underlying resin film(2a) patterned into a wiring form. A low-resistance metal(3) of Cu is subjected to film formation on the patterned underlying resin film with non-electro-selective plating. The metal wire is produced at a low cost without using a vacuum underlying method.
