摘要:
An ultraviolet-curable resin paste containing an electroless plating catalyst is applied by printing to a surface of a transparent substrate 1, and the resulting printed pattern 2 is cured by irradiation of ultraviolet light to form a resin pattern 3. Subsequently, a plating layer 4 is deposited on the resin pattern 3 by electroless plating treatment to form a conductive pattern 5. The resin pattern 3 to be subjected to the electroless plating treatment has an uncured layer 3A provided on a surface thereof. During the electroless plating treatment, the uncured layer 3A is eroded in the plating bath and particles of the catalyst are exposed. It is possible to form a satisfactory plating layer 4 using the exposed catalyst particles as nuclei. By using the ultraviolet-curable resin paste, a good conductive pattern having excellent adhesion to the transparent substrate can be formed with high accuracy, efficiently, and at low cost.

A method for manufacturing a wiring substrate includes the steps of (a) patterning a surface-active agent on a substrate having first and second areas to be remained on the first area; (b) removing residues of the surface-active agent in the second area by wet-etching with an alkali; (c) patterning a catalyst to be remained on one of the second area of the substrate and the surface-active agent; and (d) depositing a metal layer on the catalyst to thereby form a wiring.
摘要:
A nonconductor product is soaked in a solution suspending semiconducting powder and is subjected to light irradiation in the solution so that the polar group is formed on the surface of the nonconductor product, and then electroless plating is performed on the surface on which the polar group is formed. A resin product is subjected to electroless plating after ultraviolet treatment in which ultraviolet rays are irradiated through water or a solution is performed. Further, electroless plating or electroplating with a different or the same kind of metal is performed on the electroless-plated layer formed by electroless plating. With the method like this, the plated nonconductor product which does not cause the problems such as environmental pollution and waste liquid treatment, and whose surface and the plated coating is firmly adhered to each other, and, when a resin product is used as a subject to be plated, deformation by heat of the resin product can be prevented, and moreover, adherent strength of the plated coating can be improved.

Photochemical and electroless metallization techniques have been combined to create high resolution circuits with line widths and spaces of about one mil on alumina substrates. In this process, small amounts of a xylene-soluble platinum metallo-organic compound are first applied to the surface of the alumina substrate. A mask is then used to selectively expose the platinum metallo-organic compound to ultraviolet light in the areas that are to be metallized, so as to transform the platinum metallo-organic compound into a xylene-insoluble form. After a xylene rinse removes the original soluble platinum compound from the unexposed areas, the substrate is fired in air at about 450.degree. C. for about five minutes, so as to pyrolize the insoluble, irradiated platinum metallo-organic compound into catalytically active platinum. This is followed by electroless deposition of copper onto the ultraviolet-treated regions where the catalytically active platinum resides.
