A laminate that includes a metal layer that is not easily separated from a substrate, a method for producing the laminate, and a method for forming a fine conductive pattern that exhibits high conductivity, are disclosed. The peel strength of a metal layer included in a laminate that includes a polymer layer provided between a substrate and the metal layer is improved by implementing a structure in which the metal that forms the metal layer is chemically bonded to COO that extends from the polymer main chain that forms the polymer layer at the interface between the metal layer and the polymer layer. A fine conductive pattern that exhibits high conductivity can be formed by applying UV light to a pattern area of an insulating film formed on a substrate, and applying an ink prepared by dispersing metal nanoparticles in a solvent to the substrate to effect adhesion and aggregation of the ink in the pattern area, the surface of the metal nanoparticles being protected by an organic molecule layer.

An electroconductive substrate including a base material and a metal wiring made of at least either of silver and copper, and the electroconductive substrate has an antireflection region formed on part or all of the metal wiring surface. This antireflection region is composed of roughened particles made of at least either of silver and copper and blackened particles finer than the roughened particles and embedded between the roughened particles. The blackened particles are made of silver or a silver compound, copper or a copper compound, or carbon or an organic substance having a carbon content of 25 wt % or more. The antireflection region has a surface with a center line average roughness of 15 nm or more and 70 nm or less. The electroconductive substrate is formed from metal wiring from a metal ink that forms roughened particles, followed by application of a blackening ink containing blackened particles.

The present invention discloses a method for manufacturing a printed circuit board having an ultra-thin metal layer. The method discharges alkaline aliphatic amine gas and the nitrogen bubbled in the cupric sulfate solution via capacitive coupling in a vacuum, to generate low temperature plasma. The polyimide film and the epoxy resin board coated with fiberglass cloth are etched and the surface is treated to graft active groups, so as to increase the surface roughness and chemical activity. Subsequently, sputtering copper plating or chemical copper plating is directly conducted. The electroplating is conducted to thicken the copper film to a required thickness. The method of the invention not only does not need adhesive (adhesive free), but also has a high peeling strength. It can be used for the preparation of the flexible PCB, the rigid PCB, the multi-layer PCB, and rigid-flex PCB, having an ultra-thin metal layer.

A method of producing a non-planar conforming circuit on a non-planar surface includes creating a first set of conforming layers. The first set of conforming layers is created by applying an oxide dielectric layer to the surface, applying a conductive material layer to the oxide dielectric layer, applying a resist layer to the conductive material layer, patterning the resist layer according to a desired circuit layout, etching the surface to remove exposed conductive material, and stripping the resist layer. The process may be repeated to form multiple layers of conforming circuits with electrical connections between layers formed by blind microvias. The resulting set of conforming layers can be sealed.
