Abstract
An integrated circuit (IC) package substrate, comprising a magnetic material embedded within a dielectric material. A first surface of the dielectric material is below the magnetic material, and a second surface of the dielectric material, opposite the first surface, is over the magnetic material. A metallization level comprising a first metal feature is embedded within the magnetic material. A second metal feature is at an interface of the magnetic material and the dielectric material. The second metal feature has a first sidewall in contact with the dielectric material and a second sidewall in contact with the magnetic material.
