Embodiments include an inductor, a method to form the inductor, and a semiconductor package. An inductor includes a plurality of plated-through-hole (PTH) vias in a substrate layer, and a plurality of magnetic interconnects with a plurality of openings in the substrate layer. The openings of the magnetic interconnects surround the PTH vias. The inductor also includes an insulating layer in the substrate layer, a first conductive layer over the PTH vias, magnetic interconnects, and insulating layer, and a second conductive layer below the PTH vias, magnetic interconnects, and insulating layer. The insulating layer surrounds the PTH vias and magnetic interconnects. The magnetic interconnects may have a thickness substantially equal to a thickness of the PTH vias. The magnetic interconnects may be shaped as hollow cylindrical magnetic cores with magnetic materials. The magnetic materials may include ferroelectric, conductive, or epoxy materials. The hollow cylindrical magnetic cores may be ferroelectric cores.

Coaxial magnetic inductors with pre-fabricated ferrite cores

An apparatus comprises an inductor module including: a module substrate including a magnetic dielectric material; a plurality of inductive circuit elements arranged in the module substrate, wherein an inductive circuit element includes conductive traces arranged as a coil including a first coil end, a second coil end and a coil core, wherein the coil core includes the magnetic dielectric material; and a plurality of conductive contact pads electrically coupled to the first and second coil ends. The contact pads electrically coupled to the first coil ends are arranged on a first surface of the inductor module, and the contact pads electrically coupled to the second coil ends are arranged on a second surface of the inductor module.

Magnetic small footprint inductor array module for on-package voltage regulator

A low-resistance inductor is made from a plurality of first inter-abutting insulated electrode coil sub-segments that is coupled to a plurality of second intra-abutting insulated electrode coil sub-segments that are contiguous to the plurality of first intra-abutting coil sub-segments. The first plurality and the second plurality form an helical inductor unit cell. A process of forming the low-resistance inductor includes heat curing. A system includes a low-resistance inductor and a mounting substrate.
