Abstract:
1. A method for forming a multilayer wiring structure, comprising: preparing a first substrate at least one surface of which is a first adhesive face having specified adhesion that is decreased by application of a process, the process being selected from the group consisting of ultraviolet rays, heat treatment and combinations thereof; disposing droplets of a first liquid containing electrically conductive particles dispersed in a solvent on the first adhesive face; vaporizing the solvent from the droplets to form a first wiring pattern on the first adhesive face; preparing a second substrate at least one surface of which is a second adhesive face having specified adhesion; disposing droplets of a second liquid containing electrically conductive particles dispersed in a solvent on the second adhesive face; vaporizing the solvent from the droplets to form a second wiring pattern on the second adhesive face; stacking the first substrate and the second substrate such that the first adhesive face faces a first face of the second substrate opposite the second adhesive face and a through hole overlaps the first wiring pattern; and removing the first wiring pattern from the first substrate such that the first wiring pattern is transferred to the first face of the second substrate.
