Rubicon launches first commercial line of large diameter patterned sapphire substrates

Rubicon Technology announced the launch of the first commercial line of large diameter patterned sapphire substrates (PSS) in four-inch through eight-inch diameters.  This new product line provides LED chip manufacturers with a ready-made source of large diameter PSS to serve the needs of the rapidly growing LED general lighting industry.

This news is very important as growth of the LED general lighting market is expected to expand from nearly 300 million lamps shipped in 2012 to 3 billion by 2020 according to IMS Research.  Technology innovation is helping the LED supply chain prepare for this dramatic growth.  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. The larger substrates increase chipmakers’ throughput and efficiency.
