CHAMPAIGN-URBANA, ILLINOIS – April 27, 2009 – Today, EpiWorks, Inc. a leading developer and manufacturer of compound semiconductor epitaxy, announced its Phase II production facility expansion. This follows the 2007 Phase I expansion that boosted 6″ HBT production capacity to over 50,000 wafers per year.

“In 2007, we completed the internal qualification of additional MOCVD equipment. Since then, EpiWorks has successfully added new customers, developed new products and substantially increased its volume. Because we offer leading technology, quality and customer service while focusing on top-tier customers in a variety of markets, we are optimistic about our customers and our future business together. Thus, EpiWorks is now preparing to meet continued demand beyond 2009.” said Dr. David Ahmari, Executive Vice President at EpiWorks.

The phase II expansion includes doubling EpiWorks clean-room space as well as adding MOCVD capacity to allow EpiWorks to produce over 100,000 6″ wafers/year. EpiWorks offers 4″ and 6″ electronic wafer production as well as 2″, 3″, 4″ and 6″ optical wafer production.

“EpiWorks has been building capacity, a strong customer base and a profitable business over the past several years. Despite the current economic conditions, new customers and increased demand for new products are driving our growth and expansion. EpiWorks will continue to aggressively plan to meet all customer demand while balancing this aggressiveness with appropriate caution. EpiWorks has been profitable for three consecutive years, including Q4 2008 and Q1 2009, and we have planned appropriately to maintain our profitability even in the midst of the current global financial crisis. By keeping proper balance and perspective in times of extreme bullishness and bearishness, we have afforded ourselves the financial flexibility to judiciously add capacity. This will ensure that EpiWorks is well positioned to meet customer demand during the next upward cycle,” said Quesnell Hartmann, CEO at EpiWorks.
