In TFTs with Cu wiring, said TFTs having oxide semiconductor used therein as a channel layer, it is required to laminate an oxidation-resistant material on Cu, since protection films are formed in an oxidizing atmosphere.

The side wall taper angle of the laminated metal film can be controlled to 20 degrees or more but less than 70 degrees by means of wet etching.
