摘要： A touch panel having high durability is provided. Either one or both of a display device and a flexible panel have island-shaped protective bodies formed on surfaces of electrode layers (upper electrode layer, lower electrode layer), and a transparent conductive film is exposed between the protective bodies. Since the protective bodies protrude highly from the surface of the transparent conductive film, when the flexible panel is pressed and the upper electrode and the lower electrode layer are brought into contact, a load to be applied to the transparent conductive film is reduced by the protective bodies, so that the transparent conductive film is not broken.

摘要： A metallic wiring film, which is not exfoliated even when exposed to plasma of hydrogen, is provided. A metallic wiring film is constituted by an adhesion layer in which Al is added to copper and a metallic low-resistance layer which is disposed on the adhesion layer and made of pure copper. When a copper alloy including Al and oxygen are included in the adhesion layer and a source electrode and a drain electrode are formed from it, copper does not precipitate at an interface between the adhesion layer and the silicon layer even when being exposed to the hydrogen plasma, which prevents the occurrence of exfoliation between the adhesion layer and the silicon layer. If the amount of Al increases, since widths of the adhesion layer and the metallic low-resistance layer largely differ after etching, the maximum addition amount for permitting the etching to be performed is the upper limit.

摘要： A wiring film having excellent adhesion and a low resistance is formed. A barrier film having copper as a main component and containing oxygen is formed on an object to form a film thereon by introducing an oxygen gas into a vacuum chamber in which the object to form a film thereon and sputtering a pure copper target. Then, after the introduction of the oxygen gas is stopped, a low-resistance film made of pure copper is formed by sputtering the pure copper target. Since the barrier film and the low-resistance film have copper as the main component, they can be patterned at a time. Since the low-resistance film has a resistance lower than that of the barrier film, the resistance of the entire wiring film is reduced. Since the barrier layer has high adhesion to glass and silicon, the entire wiring film has high adhesion.

摘要： An electroconductive film having high adhesion and a low resistivity is formed. An electroconductive film composed mainly of copper and containing an addition metal such as Ti is formed by sputtering a target composed mainly of copper in a vacuum atmosphere into which a nitriding gas is introduced. Such an electroconductive film has high adhesion to a silicon layer and a substrate, and is hardly peeled from the substrate. Further, since the electroconductive film has a low resistivity and a low contact resistance to a transparent electroconductive film, the electric characteristics do not degrade even when it is used as an electrode film. The electroconductive film formed by the present invention is suitable particularly as a barrier film for an electrode of a TFT or a semiconductor element.
