Magnetic Thick Films for Integrated Microwave Devices
Abstract
This research aims to (1) innovate self-biased microwave magnetic thick-films on semiconductor substrates, (2) integrate permanent magnet bias magnets on semiconductor substrates, and (3) demonstrate integrated microwave magnetic components on semiconductor substrates. The key innovations include ¥ Development of magnetic thick-film deposition methods (solution-based direct-write ÒprintingÓ methods and/or directed assembly) from hexaferrite nanoparticle precursors, which offer potential for rapid, large-area fabrication, lower-temperature processing, as well as high-performance microwave/mm-wave magnetic properties ¥ Advancement of high-energy-density, high-remanence, process-integrable permanent micromagnets to replace bulky external bias magnets with compact on-chip integrated bias magnets thereby facilitating integrated microwave components using a wide variety of magnetic materials (under bias) and traditional film deposition methods ¥ Demonstration of high-performance, fully microfabricated microstrip-fed circulator components integrated on semiconductor substrates with operating frequencies ranging from 1Ð110 GHz to showcase drastically improved SWAP compared to off-chip magnetic components.
