Abstract

A magnetic micro-device and process to manufacture the same is disclosed. The magnetic micro-device has a near-zero conductivity magnetic nanocomposite film layer with a plurality of apertures through which a corresponding plurality of electrical conductors (vias) pass. Due to the near-zero conductivity of the magnetic nanocomposite film layer, the vias are self-insulating. The presence of the magnetic nanocomposite film layer results in greater inductance than that possible with an air core (or core-less) magnetic micro-device. Potential magnetic micro-devices include toroid micro-inductors, solenoid micro-inductors, toroid micro-transformers, and solenoid micro-transformers. Additional potential magnetic micro-devices include generators, motors, electromagnetic switches, and voice coils (for speakers or microphones). The process used to manufacture the magnetic micro-device can be scaled to cost-effectively produce large numbers of the magnetic micro-device.
