Rubicon Showcases Large Diameter Sapphire Products for Wafers

Rubicon Technology, Inc. (NASDAQ:RBCN), an advanced electronic materials provider that is engaged in developing, manufacturing and selling monocrystalline sapphire and other crystalline products for light-emitting diodes (LEDs), radio frequency integrated circuits (RFICs), blue laser diodes, optoelectronics and other optical applications, announced today it will exhibit large diameter sapphire products for windows and wafers including the 200kg sapphire super boule at the upcoming LASER World of PHOTONICS show in Munich, Germany held June 15-18, 2009. Show attendees can visit Rubicon in Hall 2, Booth 544.

For the first time in Europe, Rubicon Technology will be showcasing its industry leading large diameter sapphire including 200mm window and substrate products, 300mm optical windows and the 200kg sapphire super boule -- what the company believes to be the world’s largest manufactured sapphire crystal. The super boule makes available up to 320mm c-plane windows for optical applications for military, sensor, semiconductor equipment, laser and medical applications.

“Rubicon provides high quality sapphire windows and substrates in very large sizes,” said Hap Hewes, SVP Sales and Marketing. “Our 200mm windows and wafers are now available in high volumes and our super boule crystal technology allows us to offer 300mm size windows and substrates in c-plane sapphire. This technology can provide significant design and performance benefits for customers that require large area sapphire for leading edge optical window and substrate applications.”

Sapphire is an ideal material for optical uses due to its excellent transmission in UV and IR wavelengths, and rugged durability under even the harshest of conditions. Sapphire substrates are available in 2” to 8” diameters and are used in high volume production for high brightness LEDs and for high performance radio frequency integrated circuits. Key products for large area sapphire include military applications such as windows for unmanned air vehicles, targeting pods, sensor arrays and transparent armor. Other applications include aerospace windows, pressure vessel windows, semiconductor process equipment parts and sensor windows for fire safety, oil exploration and chemical processing.
