Rubicon Technology showcases large diameter sapphire products

USA - Rubicon Technology ( http:// ), a specialist integrated provider of sapphire substrates and products, exhibit large diameter sapphire products for LED wafer production, including the 200 kg sapphire Super Boule, at LED Japan/ Strategies in Light Conference in Yokohama, Japan, held on September 16 and 17, 2009.

Rubicon Technology showcased its industry leading large diameter sapphire including 150 mm and 200 mm substrate products used for LEDs and SoS RFICs. The company exhibited, for the first time in Asia, its 200 kg sapphire Super Boule -- what the company believes to be the Worlds largest manufactured sapphire crystal. The super boule provides efficient volume production of 150 and 200 mm substrates and also makes possible 300mm diameter wafers for LED and SoS RFICs as well as 400 mm windows for optical applications.

Raja Parvez, President and CEO commented; Our 150 mm and 200mm LED and SoS products are available in high volumes and our super boule crystal technology will allow us to offer up to 300 mm substrates and windows. Our fully scalable ES2 crystal growth technology platform and Sapphire processing capabilities provide our customers the ability to move to next generation large diameter LED wafer production with the comfort that these larger wafers are available in high volumes from a leading and stable vertically integrated supplier of sapphire.

Rubicons proprietary ES2 crystal growth technology and sapphire processing capabilities continue to be scaled up to produce very large size sapphire products efficiently in production volumes. Currently, Rubicon grows bulk sapphire crystals up to 200 kg with production volumes of large diameter sapphire wafers available up to 200mm Diameters and optical windows up to 300 mm dimensions.

Sapphire substrates are used in very high volume production for high brightness blue and white LEDs and for high performance radio frequency integrated circuits. Both LED and SoS RFIC production continue to migrate to larger diameter sapphire wafers.

Sapphire is also an ideal material for optical uses due to its excellent transmission in UV and IR wavelengths, chemical inertness, and rugged durability under even the harshest of conditions.
