摘要:
To the surface of a base material, there is applied, a dispersion containing fine particles of at least one metal selected from the group consisting of indium, tin, antimony, aluminum and zinc, fine particles of at least one alloy consisting of at least two metals specified above or a mixture of these fine particles, the coated layer is then fired in a vacuum atmosphere, an inert gas atmosphere, a reducing atmosphere; and subsequently the layer is fired in an oxidizing atmosphere. After this firing step in an oxidizing atmosphere, the coated layer may further be fired in a reducing atmosphere. The inert gas atmosphere is one comprising at least one inert gas selected from the group consisting of rare gases, carbon dioxide and nitrogen and the reducing atmosphere is one comprising at least one reducing gas selected from the group consisting of hydrogen, carbon monoxide and lower alcohols. A transparent electrode is composed of a transparent conductive film prepared according to the foregoing method. The present invention thus permits the formation of a transparent conductive film having a low resistance and a high transmittance while making use of a low temperature firing step.

A transparent electroconductive film having a small resistance value and a high transmittance and causing no damage upon an underlying organic EL film is formed. First and second targets are spaced and arranged in parallel, and a shielding plate is provided between the space and a transporting path for an object to be film-formed. Sputtered particles are allowed to reach the object through a release hole formed at the shielding plate. The sputtering particles obliquely irradiated are shielded by the shielding plate so that the transparent electroconductive film having a low resistivity and high transmittance can be formed.

A wiring film having excellent adhesion and barrier property and a low resistance value is formed. An oxygen gas is introduced into a vacuum chamber in which an object to be film formed is disposed; a sputtering target is sputtered in a vacuum ambience containing oxygen; and a first metallic film is formed on a surface of the object to be film formed. The first sputtering target includes copper as a major component and at least one kind of additive elements selected from an additive element group consisting of Mg, Al, Si, Be, Ca, Sr, Ba, Ra, Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb and Dy. Thereafter, a second metallic film is formed on a surface of the first metallic film by sputtering the sputtering target in a state in which the introduction of the oxygen gas into a vacuum ambience is stopped, and then a wiring film is formed by etching the first and second metallic films.

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.

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.

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.
