Executives from Rubicon Technology, Inc. (NASDAQ:RBCN), a leading provider of sapphire substrates and products to the LED, RFIC, Semiconductor, and Optical industries, will speak about the “Move to Larger Diameter Sapphire Substrates” at the Strategies in Light 2012 in Santa Clara, CA, on February 8, 2012. In order to support mass adoption of solid state lighting, a shift to larger diameter sapphire substrate size must occur. Manufacturing efficiencies and cost reductions inherent in the large diameter platform set the stage for scaling up of the entire LED supply chain to meet the growing demand for LED chips. This presentation will review why a large diameter wafer is essential to driving down costs and increasing yields to support aggressive cost targets of SSL, and will address trends that are on the horizon. As a vertically integrated supplier of sapphire substrates and products for the LED industry, Rubicon leads sapphire wafer producers in the production of high quality, high yield, large diameter wafers. To date, Rubicon has shipped more than 230,000 large diameter wafers, produced from the raw material, through cutting and finishing polished wafers. Bringing down the overall price of LEDs is a key element in supporting the worldwide commercial adoption of solid state lighting based on LEDs as a light source. According to market research firm DisplaySearch, the total average LED penetration in lighting was 1.4% in 2010 and is forecast to reach 9.3% in 2014. Government entities around the world including China, European Union, Australia, Canada and the United States have introduced legislation to require energy efficient lighting. Rubicon will be speaking about the Move to Larger Diameter Sapphire Substrates during the LED Manufacturing track at Strategies in Light 2012 on Wednesday, February 8, 4:00pm – 4:30pm.
