Abstract

See full text

A semiconductor inductor structure may include 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. 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 may also be provided. The first outer-spiral electrically conductive track may be electrically coupled to the second outer-spiral electrically conductive track and the first inner-spiral electrically conductive track may be electrically coupled to the second inner-spiral electrically conductive track. The first outer-spiral conductive track is laterally offset relative to the second outer-spiral conductive track and the first inner-spiral conductive track is laterally offset relative to the second inner-spiral conductive track.
