Diamond technology to revolutionize mobile communications
Argonne National Laboratory partners with Advanced Diamond Technologies Inc., Innovative Micro Technologiy Inc., and the University of Wisconsin-Madison to develop high-performance telecommunication devices using Ultrananocrystalline Diamond
The U.S. Department of Energy's Argonne National Laboratory has teamed with industrial and academic partners under a DARPA Phase II research and development program to develop a new technology based on Ultrananocrystalline Diamond
DARPA the Defense Advanced Research Project Agency is funding the work for advanced telecommunications systems to be used in both military and civilian applications. These devices will be fully integrated with silicon microchips to enable a new generation of high performance portable communication systems. Eventually the fruits of this project could result in enabling a variety of mobile technologies with much higher data communication rates.
Diamond is the hardest known substance on Earth. In addition, since diamond is both stiff and light, it can be used to produce tuning fork devices (tiny diving board-like structures which oscillate at high frequencies to receive and transmit signals) that vibrate at frequencies higher than similar devices of the same dimensions made of other materials--up to 100,000,000,000 times per second for diamond tuning folks that are around 100 nanometers in size. Such high frequency structures can be used as key electrical elements in cell phones, enabling them to operate at much higher frequencies. The challenge is to manufacture diamond tuning forks reliably and affordably enough for them to be widely adopted in broadband communication devices.
The four partners in the research project each bring particular expertise to the effort. Argonne provides the worldwide leading fundamental and applied science on the patented UNCD film technology developed over the last 14 years. Advanced Diamond Technologies, Inc. (ADT), a spin-off company from Argonne, is developing UNCD thin films for a number of applications, including the deposition of low-temperature films on large-area (200 mm) silicon wafers that is critical to the success of the current program. Innovative Micro Technology (IMT) has the largest and best-equipped independent MEMS fabrication facility in the world and provides MEMS services from design through production. The University of Wisconsin-Madison has advanced microfabrication facilities at the Wisconsin Center for Applied Microelectronics, and provides novel atomic force microscopy tools to characterize UNCD-based MEMS device performance. The DARPA Phase II program is funded at $1,400,000 for 12 months.
"The UNCD technology developed and patented at Argonne, and transferred to ADT for commercialization, provides the basis for a new generation of commercial MEMS devices," said Orlando Auciello, Argonne Senior Scientist and Principal Investigator of the DARPA-funded program. "UNCD exhibits exceptional mechanical and low surface friction properties that are far superior to the current silicon materials used in most MEMS devices. The team has already discovered in a Phase I of the project that UNCD exhibits the highest known acoustic velocity, which directly translates to high resonator frequencies. Both the frequency and the quality factor of these resonators are unaffected by environmental exposure, which are key requirements for real MEMS devices. The funding from DARPA is key to the challenging undertaking of developing a whole new MEMS technology based on the novel UNCD material.
About Argonne National Laboratory
Argonne is the world leader on fundamental and applied science of UNCD film technology, and carries joint work with academia and industry to perform the science needed to develop new UNCD-based MEMS and other technologies. Argonne has an extensive patent portfolio on UNCD, which has been licensed exclusively to ADT,
The nation's first national laboratory, Argonne National Laboratory conducts basic and applied scientific research across a wide spectrum of disciplines, ranging from high-energy physics to climatology and biotechnology. Since 1990, Argonne has worked with more than 600 companies and numerous federal agencies and other organizations to help advance America's scientific leadership and prepare the nation for the future. Argonne is managed by the University of Chicago for the U.S. Department of Energy's Office of Science.
About Advanced Diamond Technologies, Inc.
ADT is the world leader in the development and application of diamond films for industrial, electronic and medical applications. ADT's patented diamond, known as Ultrananocrystalline Diamond, is prized for its exceptionally small (5 nanometer) grain sizes, which are a billion-fold smaller in volume than those in traditional diamond films. It is the exceptionally small grain sizes that make UNCD distinct from other diamond films and, like other nanotechnologies, are the source of its enabling value.
Formed in December 2003, ADT provides diamond film and materials integration solutions to a variety of industry participants in diverse application areas. It is based in Champaign, IL. Its website is www.thindiamond.com.
About Innovative Micro Technology
IMT was formed in 2000, specifically to produce MEMS (micro-electromechanical systems) devices. IMT's overriding goal is to partner with companies to develop products based on MEMS technology. Its 130,000 square-foot facility contains a 30,000 square-foot clean room/fabrication facility, the largest and best-equipped such facility in the world. The company was built for high-volume manufacturing, and provides full foundry services from design through production. IMT currently has more than 150 employees and 20 customers in diverse applications, including drug discovery, drug delivery, biomedical implants and cell purifiers, microfluidics, inertial navigation, printing, various sensors, night vision, IR emitters, telephone/DSL switching, RF devices, power management, and several others. www.imtmems.com
