Abstract
A structure includes a semiconductor integrated circuit comprising a multilevel wiring network and an inductor integrated into the multilevel wiring network. 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 layer comprises a ferromagnetic alloy having an iron composition of about 10 atomic percent to about 90 atomic percent.
