Patent ID: 8533945

Claim:
A method of forming a wiring structure comprising: forming a pair of base conductors placed at an interval and facing each other above a substrate; forming an insulating film formed over each of upper surfaces of the pair of base conductors while a part of surfaces including each of opposing surfaces of the pair of base conductors is exposed; disposing catalyst materials for a wiring selectively on the part of surfaces exposed at the insulating film, using an electroless plating method over the substrate entirely including the insulating film; and forming the wiring including a first wiring made of a carbon element, a second wiring made of the carbon element, and a third wiring made of the carbon element, wherein the first wiring is electrically coupled to one of the pair of base conductors, linearly extends from the one of the pair of base conductors to the other of the pair of base conductors, and has a first portion which does not contact with the other of the pair of base conductors; wherein the second wiring is electrically coupled to the other of the pair of base conductors, linearly extends from the other of the pair of base conductors to the one of the pair of base conductors, and has a second portion which does not contact with the one of the pair of base conductors; wherein the third wiring is electrically coupled to the one of the pair of base conductors, linearly extends from the one of the pair of base conductors to the other of the pair of base conductors, and has a third portion which does not contact with the other of the pair of base conductors; wherein the first portion and a first surface of the second portion are intersected and contacted with each other to electrically coupled to each other, and a second surface of the second portion and the third portion are intersected and contacted with each other to electrically coupled to each other; wherein the method comprises: forming a metal buried in a portion between a first remaining portion other than the first portion of the first wiring and a third remaining portion other than the third portion of the third wiring.
