Abstract
A method for forming an inductor device. The method comprises forming a trench within a central core region of a conductive coil formed within a dielectric material. The method further comprises forming a composite region within the trench. The composite region including a polymer matrix having a plurality of particles with magnetic properties dispersed therein with the central core region to reduce eddy current loss and increase energy storage.
