CHAMPAIGN-URBANA, ILLINOIS – August 5, 2003 – Today, Illinois based EpiWorks, Inc., a leading developer and manufacturer of compound semiconductor epitaxial wafers announced the existence of its red laser development program.

David Ahmari, EpiWorks’ Executive Vice President of Business Development, stated, “Red lasers operating from 630nm to 670nm are key optical devices in many existing and emerging applications, such as medical, laser pointers, DVD and display. With select industry development partners, we have been developing MOCVD-based processes to provide high performance epitaxial wafers for a variety of applications requiring wavelengths ranging from 630nm to 670nm.”

This effort initially focused on developing longer wavelength red lasers and has recently moved towards 630nm. Although much of the development effort is complete, EpiWorks is still entertaining opportunities with customers who would like a state-of-the-art capability customized for their red laser needs. EpiWorks expects various products to be production qualified throughout 2003.

David Ahmari said, “Although we are not yet completed with our development efforts, EpiWorks’ material has shown excellent promise to provide superior performance to what is currently available. This material performance combined with EpiWorks’ customer interaction produce the ideal co-development partner.”

“This effort is another building block in our effort to provide leading epitaxy wafer performance and breadth of product offerings for our customers. We place a high level of emphasis on continuing to offer new products and co-development opportunities for our customers.” Added Quesnell Hartmann, President of EpiWorks.
