Rubicon Technology, 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 4” and 6”polished sapphire wafers for the LED industry at LED Taiwan 2015. The event will be held at TWTC Nangang Exhibit Hall in Taipei, Taiwan, March 25-28, 2015. Rubicon will exhibit its line of sapphire products in Booth #N0326 & N0328.

Rubicon offers highly customizable sub-micron 4” and 6” PSS 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.

Bill Weissman, CEO of Rubicon, said: “Patterning has greatly increased light extraction efficiency for LED manufacturers. As these companies continue to seek greater manufacturing efficiency, they are increasingly turning to larger wafers. Rubicon is uniquely positioned to help LED manufacturers transition to larger-diameter PSS, and we have end-to-end control of all aspects of sapphire production, from raw material and crystal growth through polishing and patterning, to maintain exceptional quality and reliability.”

Rubicon will have a number of sapphire products for the LED market on display in Booths N0326 & N0328including sapphire cores, large-diameter wafers ranging in size from 4 inches to 6 and 8 inches, and information about large-diameter patterned sapphire substrates.
