Abstract

Methods/structures of forming embedded inductor structures are described. Embodiments include forming a first interconnect structure on a dielectric material of a substrate, selectively forming a magnetic material on a surface of the first interconnect structure, forming an opening in the magnetic material, and forming a second interconnect structure in the opening. Build up layers are then formed on the magnetic material.
