Even more LEDs

Barely a month goes by without further evidence of the rapid growth in LED related areas. This month is no exception with figures showing the impact of the National Semiconductor Illuminating Project in China. In 2010, the growth of AlGaInP/AlGaAs/GaAsP/GaP epitaxial wafers, mainly used in red light LED products, accounted for 60.2% of the total epitaxial wafer output. Driven by the rapidly expanding markets for blue and white light LEDs in landscape lighting and backlighting, the GaN epitaxial wafer output accounted for 39.8% of China’s total epitaxial wafer output in 2010. However it is expected that the GaN epitaxial wafer output will exceed that of AlGaInP in 2011. No wonder that Aixtron believe that there is a market for a 16 x 4 inch or 69 x 2 inch MOCVD reactor.
