Patent ID: 7714410

Claim:
A semiconductor device, comprising: a semiconductor substrate that has an integrated circuit and at least a first electrode and a second electrode, the first and second electrodes being electrically coupled to the integrated circuit; a resin layer that is formed on the semiconductor substrate, the resin layer having an upper surface and a lower surface, the upper surface and the lower surface opposing each other, the lower surface facing the substrate; and a spiral inductor that is formed on the upper surface of the resin layer with a spiral wiring line, the spiral inductor including a first terminal end electrically coupled to the first electrode and a second terminal end electrically coupled to the second electrode, the wiring line having edges in a width direction between the first and second terminal ends and a mid-portion between the edges, wherein at least a part of the mid-portion makes contact with the upper surface of the resin layer such that the edges are positioned apart from the upper surface of the resin layer by a gap.
