摘要:
A process for producing a spacer for a liquid crystal display apparatus whereby an ink-jet method is used to print droplets composed of an ink that contains a resin and a solvent that dissolves it but that contains essentially no solid particles on a substrate 23, and the solvent is removed from the droplets on the substrate 23 to form a spacer 11 situated at a prescribed location on the substrate 23, wherein A in the following formula (1) is −10 to 15 mJ/m2, where X mN/m is the surface tension of the ink at 25° C. and Y mJ/m2 is the surface free energy of the substrate 23 at 25° C. A=X−Y (1)

There are provided are a method wherein a surface treating agent, which is essential for making copper particles antioxidative and dispersing the copper particles in the prior art, is hardly used but copper particles, which cause little electromigration and are small in the price rate of material itself, are used to form a low-resistance copper wiring pattern while the generation of cracks therein is restrained; and a copper oxide particle dispersed slurry used therein.The method is a method for forming a copper wiring pattern including the step of using a dispersion slurry wherein copper based particles having a copper oxide surface are dispersed to form any pattern over a substrate, and the step of reducing the copper oxide surface of the copper based particles in the pattern with atomic form hydrogen to return the oxide to copper, and sintering particles of the copper metal generated by the reduction and bonding the particles to each other.

Disclosed are: a copper metal film which has good adhesion to a substrate, low volume resistivity, and good deep-part metal properties; and a method for producing a copper metal film, wherein the copper metal film can be produced by reducing a substrate to a deep part thereof without damaging the substrate. Specifically disclosed is a copper metal film obtained by treating a copper-based particle deposition layer containing both copper oxides and a metallic transition metal or alloy, or a transition metal complex containing a metal element, with gaseous formic acid and/or formaldehyde heated to 120° C. or higher. The copper oxide is preferably copper (I) oxide and/or copper (II) oxide. The transition metal, alloy or metal complex are preferably a metal selected from the group consisting of Cu, Pd, Pt, Ni, Ag, Au and Rh, an alloy containing the metal, or a complex containing the metal element, respectively.
