1. An inductor comprising:
a coil having a core area, the core area being an area surrounded by the coil; and
a substrate, wherein the substrate is partially coated to provide a coated substrate portion and an uncoated substrate portion, wherein the coated substrate portion fills the core area such that a first portion of the coil at a first surface of the substrate passes through the substrate and couples to a second portion of the coil at a second surface of the substrate, wherein a substrate material of the coated substrate portion and a substrate material of the uncoated substrate portion are identical substrate material, and wherein the substrate and the core area include an identical material.
