Patent ID: 7750434

Claim:
A circuit substrate structure comprising: a first wiring layer comprising a first wiring pattern of a spiral configuration and a second wiring pattern of a spiral configuration; a dielectric layer provided with a first via and a second via which are electrically connected to the first wiring pattern and the second wiring pattern, respectively; and a second wiring layer comprising: a bridge electrically connecting the first via and the second via; and a conductive pattern around the bridge, an outer edge of the conductive pattern being located outside an outer edge of the first wiring pattern and the second wiring pattern in the first wiring layer, wherein the bridge functions in the second wiring layer as a coplanar line by being surrounded by the conductive pattern, and a gap between the bridge and the conductive pattern in the second wiring layer is smaller than a distance between wires in the first wiring pattern or in the second wiring pattern.
