A microelectronics package, comprising a substrate comprising a first bondpad and a second bondpad over a dielectric. An inductor comprising at least one wire extends over the dielectric. The at least one wire has a first end coupled to the first bondpad and a second end coupled to the second bondpad, and an inductor core layer over the dielectric. The inductor core layer comprises a magnetic material. At least a portion of the inductor extends within the inductor core layer.
