Rubicon Technology, Inc., (Nasdaq: RBCN), a leading provider of sapphire substrates and products to the LED, RFIC, semiconductor, and optical industries, announced today that it has been selected as a Deloitte Technology Fast 500™ award winner for 2012. The Deloitte’s 2012 Technology Fast 500™ is an annual ranking of the fastest growing technology, media, telecommunications, life sciences and clean technology companies in North America. Deloitte Technology Fast 500 award winners for 2012 were determined based on percentage fiscal year revenue growth from 2007 to 2011. In order to be eligible for Technology Fast 500™ recognition, companies must own proprietary intellectual property or technology that is sold to customers in products that contribute to a majority of the company's operating revenues. “Rubicon is proud to be part of the Deloitte Technology Fast 500,” said Raja M. Parvez, President and Chief Executive Officer of Rubicon. “Drawing on more than a decade of experience and our culture of innovation, Rubicon’s technological leadership extends from raw material and crystal growth through finished sapphire wafers. This leadership enables Rubicon to deliver the highest quality, most reliable supply of industrial sapphire to meet the evolving and exacting specifications of their customers in the LED, RFIC/SoS and optical markets.” Rubicon is the world’s largest, most experienced and most reliable provider of large-diameter sapphire wafers. As a vertically integrated supplier, Rubicon perfected the process to grow large sapphire crystals from raw materials in custom-built, proprietary furnaces replicating the organic sapphire creation process found in nature. As a result, Rubicon has been able to scale the growth of bulk crystal from 30 kg to 85 kg to 200 kg without compromising high quality or high yield. Rubicon’s intellectual property and innovations from raw materials and crystal growth through the wafer finishing process enable efficiencies that ultimately translate into savings for Rubicon customers. To date, Rubicon has shipped more than 340,000 six-inch polished wafers to the LED and SoS markets.
