Rubicon showcasing large-diameter patterned sapphire substrates for LED market

In booths N0326 & N0328 at LED Taiwan 2015 in Taipei (25-28 March), Rubicon Technology Inc of Bensenville, IL, USA (which makes monocrystalline sapphire substrates and products for the LED, semiconductor and optical industries) is showcasing large-diameter patterned sapphire substrates (PSS) as well as its line of 4" and 6" polished sapphire wafers for the LED industry.

Rubicon offers highly customizable sub-micron 4" and 6" PSS with tight dimensional tolerances (within ±0.1µm). With an edge exclusion zone as small as 1mm, the firm offers LED chip makers 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.

"Patterning has greatly increased light extraction efficiency for LED manufacturers," notes CEO Bill Weissman. "As these companies continue to seek greater manufacturing efficiency, they are increasingly turning to larger wafers," he adds. "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."

At LED Taiwan, Rubicon has a number of sapphire products for the LED market on display, including sapphire cores, large-diameter wafers ranging in size from 4-inches to 6- and 8-inches, and information about large-diameter patterned sapphire substrates.
