The local AIXTRON support team will commission the new reactors at the facility within the company’s research group,ISCAS, in China.General Manager Dr. Wang GuoHong, comments, “Our reason for purchase was an outstanding need for capacity increase. Up to now our research group, ISCAS, has been using our first AIXTRON system and they are very satisfied with the system's all round performance. Now, however, we need a new capability that gives us high throughput but with lower cost and easy operation. We are convinced that we will get all these features and more from the world-class CRIUS® MOCVD reactors supplied by AIXTRON. Backed up by their excellent service and support they will give us the complete package.”For further information on AIXTRON AG (FSE: AIXA, ISIN DE000A0WMPJ6; NASDAQ: AIXG, ISIN US0096061041) please consult our website at: www.aixtron.com.Forward-Looking StatementsThis news release may contain forward-looking statements about the business, financial condition, results of operations and earnings outlook of AIXTRON within the meaning of the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995.
