Microelectronic magnetic structure, device including the structure, and methods of forming the structure and device

摘要

An improved magnetic structure suitable for electronic applications is disclosed. The magnetic structure may be formed on or within a substrate such as a printed circuit board by forming a layer of magnetic material, pattering the layer of magnetic material, and etching the layer to form the magnetic structure. Various insulating layers and/or conductive layers may then be formed over the magnetic structures as part of the substrate. Inductors suitable for use in power supplies may be formed using the magnetic structures of the present invention.
