DESCRIPTION
Novel fabrication of 0-3 soft magnetic nanocomposites for improved on-chip power components
Inductors and transformers (here referred to as power components) for modern, AC/DC switching power supplies require magnetic materials that have high power density and efficiency at higher frequencies. Rather than using a single-phase magnetic material in a polymer-based composite, a composite formed from two magnetic phases (such as a 0-3 nanocomposite) can achieve increased magnetic energy storage and power handling, benefiting from contributions by both the 0D and 3D phases. The fabrication of 0-3 magnetic nanocomposites for power component applications requires a method that can achieve multi-micrometer thickness in a CMOS-compatible fashion. Here, the deposition of magnetic materials into microns-thick composites using two methods is discussed: electrophoretic deposition (EPD) coupled with electro-infiltration (EI) and aerosol deposition (AD). Both methods fully incorporate a second magnetic material to produce an entirely magnetic 0-3 nanocomposite, which leads to a promising approach to power component fabrication at a reduced scale that is compatible with state-of-the-art semi-conductor processes.
