Rubicon to showcase large-diameter patterned sapphire substrates at LED Korea

Rubicon Technology Inc of Bensenville, IL, USA (which makes monocrystalline sapphire substrates and products for the LED, RFIC, semiconductor and optical industries) is showcasing its large-diameter patterned sapphire substrates (PSS) - launched last October - as well as its line of 6”polished sapphire wafers for the LED industry at LED Korea 2014 in booth #4707 at the Convention and Exhibition Center (COEX) in Seoul (12-14 February).

Technology innovation is helping companies in the LED supply chain prepare for dramatic growth in LED lighting, says Rubicon. Most high-brightness LED makers 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 claims to be the first to offer highly customizable 6” and 8” PSS. Rubicon is providing LED chip makers 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.

“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,” claims says president & CEO Raja M. Parvez. “This advance helps LED manufacturers gain the efficiency of larger diameters, combined with the industry’s most precise patterning capability,” he adds.

Rubicon offers fully customizable sub-micron patterning capability with tight dimensional tolerances (within ±0.1µm). The firm adds that, with an edge exclusion zone as small as 1mm, it offers 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.
