Next Generation Large Diameter Sapphire Furnaces are Launched by Rubicon Technology

Aug 18, 2011 Rubicon Technology announced that the company has completed a company-wide installation of enhancements to its proprietary crystal growth furnaces bringing all furnaces up to Rubicon Furnace VersionES2-XLG3.0.This is the latest version of the company's proprietary furnace design for the production of high quality, large diameter sapphire material and provides even greater automation and yield consistency.

Over time, the company's Design for High Volume Manufacturing (DHVM) approach has led to numerous furnace design improvements that have created an industry-leading equipment platform for high volume sapphire crystal growth. Rubicon Furnace VersionES2-XLG3.0provides even greater automation resulting in additional yield improvements. The ES2-XLG3.0 encompasses numerous innovations and now operates in Rubicon's United States high-efficiency crystal growth facilities in Batavia and Bensenville, Illinois.

"Compared to the production of other substrate materials, sapphire crystal growth is extremely complex," explains Raja Parvez, Rubicon President and CEO. "Variables such as stable power, growth profiles, cooling profiles and feedback controlmechanisms must be optimally managed to maximize the yield of quality sapphire crystal. This is even more vital when producing sapphire for the expanding large diameter wafer market. With hundreds of years of combined experience and innovations such as those embedded in the Rubicon Furnace Version ES2-XLG3.0, Rubicon's design and equipment engineers and material scientists have achieved industry leading yields and performance."

The Rubicon furnace design is just one component of the company's efficient equipment platform that has differentiated the company in the large diameter sapphire wafer market. This effort, combined with Rubicon's robust process platforms and the company's ability to scale to high volume, creates superior performance factors for the LED industry. With the Batavia crystal growth facility qualified with more than a dozen customers and the Malaysia polishing facility now also qualified, Rubicon has successfully shipped more than 100,000 six inch sapphire wafers.

The transition to larger diameter wafers in LED production has started. Several key LED chip manufacturers have announced plans to migrate to and/or test large diameter wafers in 2011/2012.
