Abstract
An integrated circuit has a semiconductor die provided in a first IC layer and an inductor fabricated on a second IC layer. The inductor may have a winding and a magnetic core, which are oriented to conduct magnetic flux in a direction parallel to a surface of a semiconductor die. The semiconductor die may have active circuit components fabricated in a first layer of the die, provided under the inductor layer. The integrated circuit may include a flux conductor provided on a side of the die opposite the first layer. PCB connections to active elements on the semiconductor die may progress through the inductor layer as necessary.
