Patent ID: 8836460

Claim:
A semiconductor inductor structure comprising: a first spiral structure, located on a first metal layer, having a first outer-spiral electrically conductive track and a first inner-spiral electrically conductive track separated from the first outer-spiral electrically conductive track by a first dielectric material; and a second spiral structure, located on a second metal layer, having a second outer-spiral electrically conductive track and a second inner-spiral electrically conductive track separated from the second outer-spiral electrically conductive track by a second dielectric material, the first outer-spiral electrically conductive track electrically coupled to the second outer-spiral electrically conductive track, the first inner-spiral electrically conductive track electrically coupled to the second inner-spiral electrically conductive track, and the second outer-spiral electrically conductive track electrically coupled to the second inner-spiral electrically conductive track, wherein the first outer-spiral electrically conductive track is laterally offset relative to the second outer-spiral electrically conductive track and the first inner-spiral electrically conductive track is laterally offset relative to the second inner-spiral electrically conductive track.
