  1. (1) Brief View of Materials Research in Functional Materials(2) Commercialization Processes Professor of Materials Science and Engineering Executive Director of Technology Commercialization Programs Email: Angus_kingon@ncsu.edu

  2. Outline • Mention of the projects in the Kingon research group, especially those related to NASA • Few words on our technology commercialization programs

  3. Mainstream Silicon Devices: Gate Dielectrics • Development of new dielectrics to replace SiO2, and the gate metals • Part of the NCSU-led Front End Process Center • Primarily SRC/Sematech funded • 9 universities, about 25 faculty

  4. Ferroelectric Memory • Development of ferroelectric thin films for ferroelectric nonvolatile memory • Low density devices now in commercial production • Many materials issues associated with the development of high density devices • NCSU role • New materials • Advanced characterization techniques based upon scanning probes

  5. Two Critical Core Competencies • Dielectric and ferroelectric materials, especially thin films • Composite dielectrics • Materials such as (Ba,Sr)TiO3 (or ‘BST’) which are nonlinear dielectrics • Flexible substrates • Metal • Polymer

  6. Nonlinear Dielectrics for RF/Microwave Frontends • Voltage tunable dielectrics • Allows design of frequency agile front end systems • Varactors for band pass filters • Frequency tunable antenna systems • Different approaches for different frequencies (patch, microstrip, resonator, EBG)

  8. Conventional Band Pass Filter Design • Lumped element circuit • 200 MHz Chebychev design

  10. Embedded Passive Components • Composite dielectrics in polymer based flexible substrates (ie HDI) • Replace surface mounted components • Generation 2 commercialized (35 million cell phones) • Generation 3 being scaled

  11. Dielectrics on Flexible Substrates

  12. Gossamer • Qortek/PSU/NCSU • Polymer-based actuators • Flexible electronic circuit on Kapton/copper

  13. Piezoelectric Applications • Novel Cooling Concepts • Acoustic streaming • Development of acoustic resonators • Analytical modeling of piezoelectric actuators in bending mode

  14. Flexible Sensor Networks • US Air Force Project just initiating • Strain, acceleration, pressure sensors on large flexible ‘tiles’ which are embedded onto wings structures • Antenna array for data communication to the fuselage

  15. Stressed Unimorphs • Type of low cost bending mode piezoelectric actuator • Long-term development of these materials at NASA-Langley (plus spin-out) • We have developed applications for these types of actuators • DARPA microrobot program • Piezoelectric solid state motors

  16. Rotary Thundermotor with Tachometer Wheel

  17. GSFC Space Telescope • Discussion only • Need for shutter arrays

  18. Part 2: Technology Commercialization Programs

  19. Technology Entrepreneurship and Commercialization Program • Unique program • Develops viable business propositions from technology sources • Two routes • Using MBA and Ph.D science/engineering students in a 3 course sequence • Using professional business analysts • NASA one of the sources of technology (eg Langley optical sensors

  20. Program Uniqueness • Process or methodology for the this “fuzzy front end” of innovation • Emphasis on high tech, high growth potential

  21. Program Impact • Created > 400 jobs • Raised more that $120 million of venture funding • Assisted the business development of about 20 companies • Many other outcomes • url: www.tec.ncsu.edu
