Rubicon Technology, Inc. (NASDAQ:RBCN), a leading provider of sapphire substrates and products to the LED, semiconductor, and optical markets, today announced that it will showcase large-diameter patterned sapphire substrates (PSS) as well as its line of 6”polished sapphire wafers for the LED industry at LED Korea 2014 at COEX, Seoul, Korea, February 12-14, 2014. Rubicon will exhibit its line of sapphire products in Booth #4707. Technology innovation is helping companies in the LED supply chain prepare for dramatic growth in LED lighting. Most high-brightness LED manufacturers etch a pattern into the sapphire wafers in order to both improve epitaxial growth and extract more light from each chip. Patterned sapphire substrates have been available for purchase in smaller diameters, but Rubicon is the first to offer highly customizable 6” and 8” PSS. Rubicon is providing LED chip manufacturers with a ready-made source of PSS in 4”, 6” and 8” -diameters to serve the needs of the rapidly growing LED general lighting industry. “Rubicon Technology continues to pioneer innovations in sapphire substrates,” said Raja M. Parvez, President and CEO, Rubicon Technology. “As the world’s most experienced provider of 6-inch sapphire wafers, Rubicon is uniquely positioned to drive the evolution of substrates – patterning large diameter sapphire substrates. This advance helps LED manufacturers gain the efficiency of larger diameters, combined with the industry’s most precise patterning capability, all from a supplier known for quality and reliability at high volume.” Rubicon offers fully customizable sub-micron patterning capability with tight dimensional tolerances, within ±0.1 µm. With an edge exclusion zone as small as 1 mm, Rubicon offers LED chip manufacturers more usable area to maximize the number of chips per wafer. Patterning is available in a range of shapes including cone, dome and pyramid, and in a range of orientations.
