Japanese market research firm, Yano Economic Research Institute survey showed that the amount calculated according to the manufacturer's supplier, in 2012 the global power semiconductor market size is of $ 13.512 billion, 11.5% less than last year. Power semiconductor market had the rapid decline in 2009, in 2010 and 2011, had two consecutive years of recovery, but due to the economic downturn of the Chinese and European markets, PCs, displays and consumer products, power semiconductor demand in the doldrums, in 2012 it was of double-digit reduction. In addition, Japan and North America, pure electric vehicles, hybrids and photovoltaic power generation power regulator uses power semiconductor demand growth. The survey period from October 2012 to April 2013, the object including power semiconductor manufacturers, semiconductor foundries and application equipment manufacturers. Yano Economic Research Institute believes that the power semiconductor market will likely begin to recover from the second half of 2013. 2013 the market size is expected to reach 4.1% to $ 14.07 billion more than last year, the market will reach $ 29.01 billion in 2020, more than double the 2012. In addition, Yano Economic Research Institute believes that the power semiconductor market traction from discrete MOSFET and diode products to power module. Power module areas of demand for industrial equipment, new energy, pure electric vehicles and hybrid vehicles, rail and power infrastructure is expected to achieve long-term growth in the field. The new generation of power semiconductor global market will reach about $ 3 billion in 2020. Yano Economic Research Institute forecasts, using a new generation of SiC and GaN power semiconductors costs continue to decrease, after 2015 it will be widely used. The company expects that these next-generation global market for power semiconductors, from 2012 to 2020 will average 57.2% growth rate in 2020 will expand to $ 2.98 billion. SiC power semiconductors currently used mainly SiC diode ,it is estimated that from 2013 to 2014, involved in SiC transistor manufacturers will more and more. The estimated 6-inch wafers will be put on the market a large number of 6-inch wafer production will remain stable the SiC transistor costs will decline after 2015.
