and Nanotechnology for commercial applications.
Prior to establishing the MEMS and Nanotechnology Exchange, Dr. Huff was on the faculty in the Department of Electrical Engineering at Case Western Reserve University (CWRU) in Cleveland, Ohio. At CWRU his research was focused on developing MEMS microfluidic components for healthcare and defense applications, including a novel MEMS-based insulin pump, which received national attention. Before joining the faculty at CWRU, Dr. Huff held the position of Technical Fellow at the Baxter Healthcare Corporation in Chicago, Illinois and directed Baxter's corporate-wide efforts in applying MEMS technology to novel medical devices, which resulted in several new products. At Baxter, he was also very active in managing product development in more mature technology domains such as infusion pumps, blood warmers, etc., as well as conducting technical due diligence on potential acquisitions.
Dr. Huff has actively participated in MEMS research and development for nearly twenty years and has published numerous papers on MEMS devices and fabrication technologies. Dr. Huff holds several patents for MEMS devices, and has several others pending. His principal technological accomplishments in the MEMS technology domain include: the development of shape-memory materials for high force and large displacement actuators; the development of many novel microfluidic devices and systems; the development of shape-memory alloy as an extremely high-gauge factor strain sensing material; the advancement of silicon wafer bonding as a MEMS fabrication technology; the development of silicon wafer bonding as a technique for MEMS packaging; the development of a thick polysilicon surface micromachined process for higher force or higher capacitive sense applications; the development of a Bond and Etch Back Silicon-On-Insulator (BESOI) process; the demonstration and determination of compressive stress levels in Boron etch stop layers; the development and demonstration of thermal micromachined devices having one of the broadest thermal bandwidths ever reported; commercialization of several MEMS microfluidic devices; the development of MEMS on LTCC for microwave and RF applications; the demonstration of distributed fabrication of MEMS as a viable method to implement high-quality devices; and many others.
Dr. Huff received a B.S. degree in Electrical Engineering with Highest Honors from Georgia Institute of Technology. He spent several years working at the Missile Systems Division of Raytheon Corporation where he designed the front-end signal acquisition system for the Patriot Missile Platform. He was awarded the M.S. in Electrical Engineering and Computer Science and simultaneously the M.S. in Material Science and Engineering with a specialization in Electronic Materials from the Massachusetts Institute of Technology in Cambridge, MA. His thesis was under the supervision of one of the most notable pioneers of MEMS technology, Prof. Roger Howe, and involved the design and fabrication of a thermally-isolated microstructure for tin-oxide gas sensors. This thesis work was supported by General Motors Research in Warren, Michigan. Dr. Huff was awarded a Ph.D. in Electrical Engineering and Computer Science from MIT. There his thesis was under the supervision of Profs. Schmidt and Senturia. His thesis involved the design and fabrication of a wafer-bonded electrostatically-actuated pressure-balanced microvalve that could operate at very high fluid pressure levels, and was supported by the Robert Bosch Company in Stuttgart, Germany. He also developed a novel threshold pressure switch using wafer bonding that employed mechanical hysteresis in a plastically-deformed thin silicon diaphragm. His thesis pioneered the now commonly used fabrication technique of silicon wafer bonding for MEMS fabrication. Dr. Huff is responsible for overall management of the MEMS Exchange and is actively involved in lending his expertise and knowledge on various MEMS Exchange customer development efforts.
Dr. William Benard is a Senior Engineer at the MEMS and Nanotechnology
Exchange and
is responsible for handling customer requests on design and
fabrication services offered by the MEMS and Nanotechnology
Exchange. Dr. Benard
received the B.S. degree in Electrical Engineering from the University
of Witwatersrand, Johannesburg, South Africa, in 1993 and the
M.S. degree in Electrical Engineering and Applied Physics from Case
Western Reserve University, Cleveland, Ohio, in 1997. While at Case
Western Reserve University, he was actively involved in researching
various MEMS microfluidic components based on thin-film
Titanium-Nickel (TiNi) shape-memory alloy actuators. In this research
activity he designed, fabricated, and tested various microvalve and
micropump configurations leading to several publications. This work
was widely recognized as a compelling demonstration of shape-memory
actuation for microfluidic devices and systems.
Dr. Benard completed the Ph.D. in Electrical Engineering at Carnegie-Mellon University in Pittsburgh, PA in 2003. His thesis topic focused on MEMS manufacturing and work flow modeling for a MEMS foundry. This work was very important in that it demonstrated that MEMS manufacturing is best classified as a "job shop" manufacturing environment rather than a "flow-shop" manufacturing environment, which is more applicable to the Integrated Circuit (IC) manufacturing domain. Recognition of this important difference radically changes the business practices and economics of MEMS manufacturing. Dr. Benard also developed new scheduling and workflow modeling techniques that improve the performance of MEMS foundries and these techniques are being put into place by the MEMS and Nanotechnology Exchange in order to improve quality and turn-around times at the participating foundries. Dr. Benard provides process and design engineering expertise to MEMS and Nanotechnology Exchange customers.
Dr. Mehmet Ozgur is a Senior Engineer at the MEMS and Nanotechnology
Exchange. Dr. Ozgur received the B.S. and

three years before returning to the Pennsylvania State University to
complete his Ph.D., also in Engineering Science and Mechanics.
During his time at Penn State, Dr. Sunal investigated various aspects of engineered thin film morphologies. Specifically, micro- and nanostructured thin films such as sculptured thin films (STFs) and metal/nitride nanocomposites were studied. His work focused on determining the level of control over the resulting structure at all length scales (macro-, micro-, nanoscale) and methods of thin film characterization. Part of the time at Penn State was spent fabricating Pd hydrogen gas sensors upon permeable, heated MEMS platforms that allowed regeneration of the sensors, thereby increasing their lifetimes and sensitivity.
