Abstract
A structure comprises a semiconductor integrated circuit, an inductor, and a magnetic flux closure layer. The inductor is integrated into a multilevel wiring network in the semiconductor integrated circuit. The inductor includes a planar laminated magnetic core and a conductive winding that turns around in a generally spiral manner on the outside of the planar laminated magnetic core. The planar laminated magnetic core includes an alternating sequence of a magnetic layer and a non-magnetic layer. The magnetic flux closure layer is disposed within about 100 μm of a face of the planar laminated magnetic core, the face of the planar magnetic core parallel to a principal plane of the planar laminated magnetic core. A second magnetic flux closure layer can be disposed within about 100 μm of an opposing face of the planar laminated magnetic core.
