NEW YORK, March 14, 2008 (PRIME NEWSWIRE) -- While the headlines carry news of a lagging U.S. economy and a sagging U.S. dollar, executives from one small-cap manufacturing company in Illinois opened the NASDAQ market yesterday and quietly celebrated the company's performance since their November 2007 initial public offering.

Rubicon Technology, Inc. (NasdaqGM:RBCN - News) manufactures sapphire substrates and materials that are used by their customers in manufacturing LED's, radio frequency integrated circuits and blue laser diodes. Growing demand for high-efficiency LED lighting and smaller, high-performance electronic devices has kept the suburban Chicago company increasingly busy. ``Coming here to the NASDAQ for this ceremony has been exciting,'' said Rubicon CEO Raja Parvez after taping an interview. ``Ideally, I would have had every Rubicon employee here with me, because they have made all of this possible. However, our customers, the other group of people who have made this possible, prefer we keep our production running.''

When asked about the company's financial performance in light of the current economic conditions, CFO William Weissman attributed the company's success to Rubicon's crystal growth technology, efficient production, and growing market demand.

Rubicon's stock had opened at $14.00 per share in November 2007 and closed yesterday at $27.87.
