in producing large diameter sapphire wafers than any of our competitors,” explains Raja Parvez, Rubicon President and CEO. “LED manufacturers understand that migration to a large diameter sapphire wafer platform offers an opportunity to achieve production and cost efficiencies. This is increasingly important as LED manufacturers seek to reduce costs throughout the LED manufacturing process to help the industry lower prices of LED- based lighting and encourage adoption worldwide.”
Bringing down the price of LEDs is a key element in supporting the worldwide commercial adoption of solid state lighting based on LEDs as a light source. Government entities around the world including Australia, Canada and the United States have introduced legislation to require energy efficient lighting. The transition to larger diameter wafers in LED production has started. Several key LED chip manufacturers have announced plans to migrate to and/or test large diameter wafers in 2011/2012.
“There is significant large diameter wafer activity among LED manufacturers with nearly a half dozen working with six-inch in some way,” said Dr. Philippe Roussel, LED Senior Project Manager, Yole Développement. “By 2016, our research projects that large diameter wafers measuring six inches and greater will capture more than 50 percent of the market.”
According to market research firm DisplaySearch, TV applications currently dominate the LED market, but LED lighting will capture the lead by 2014. The firm said that LED lighting penetration rate in 2010 was 1.4%, and is forecast to reach 9.6% in 2014 with the growth due to government incentive programs, and growth in commercial applications and consumer adoption worldwide.
Sensor Electronic Technology gears up for high volume manufacturing of UVLEDs
Manufacturer of short wavelength UV LEDs, Sensor Electronic Technology have announced that it has put an expansion plan in motion to both expand its R&D efforts and to transition to its production line to

high volume manufacturing, making it the first high volume supplier of UV LEDs shorter than 365nm, initially scaling to supply quantities of over 100 million LEDs per year.
SETi was first to market with short wavelength UV LEDs in 2004 and has remained the leading supplier with its product portfolio of LEDs and high power LED lamps from 240nm to 355nm.
SETi currently operates a 15,000 sq.ft. ISO9001 certified facility in Columbia, SC, where it runs a vertically integrated R&D and small volume production line with epitaxial growth, chip fab, packaging and test and analysis, plus a prototyping line for integration of its LEDs into complete systems. The first phase of the expansion, currently underway, involves retrofitting this facility to 20,000 sq.ft and converting it to the company’s R&D center. The expansion in this facility will predominantly be focused around additional clean room space for chip fab and device packaging, where new mask designs, processing techniques and packaging solutions will be developed to further improve the performance of SETi’s UVTOP® and UVClean® devices and ensure that SETi maintains its world leading position in the UV LED market.
SETi has recently closed on the purchase of a new property, also in Columbia, SC, where it will focus its high volume manufacturing lines. SETi’s growth plans include the expansion of this new facility to 130,000 sq.ft. Initially, this facility will house SETi’s proprietary production MOCVD reactors where the company will focus on the high volume manufacturing of its MEMOCVD® process that will be used for the scale up in volume of its UV LEDs and a new Engineering Center for the development of new applications and production of custom solutions.
