In 2013 global power semiconductor market size (value calculated by supplier) grew 5.9 percent over the previous year, to $ 14.313 billion. Although 2012 was negative growth, but the demand of the Chinese market recovery in 2013, the steady growth of the automotive sector and the expansion of new energy investment in equipment has played a role. It is expected to continue to grow in 2014 , in 2015 after demand white goods, automotive and industrial equipment in the field is expected to expand. Yano Economic Research Institute predicted that in 2020 the global power semiconductor market size (amount calculated by supplier) will reach $ 29.45 billion. All kinds of devices, it is expected the highest growth rate of the power module, the popularity in the field of next-generation vehicles (HV and EV), new energy equipment and factory equipment, is expected to expand. Aspects, it was mainly to be used for the diode, and 2013 onwards, some transistors are beginning to use SiC. Since the second half of 2014, each component manufacturers began using a diameter of 6 inches (150mm) of the SiC wafer implementation of mass production in 2015 - 2016 will reduce costs, usage will be further expanded. Yano Economic Research Institute predicted that in 2020 the global market size of the new generation of power semiconductors (amount calculated by supplier) will reach $ 2.82 billion, driven in SiC power semiconductors. The object of the survey for power semiconductor manufacturers, fab manufacturers and system vendors, in October 2013 - June 2014 implemented. The device includes a power involving MOSFET, IPD (Intelligent Power Device), diodes, IGBT, bipolar transistors or the like, and power modules. According to the survey data, and the use of SiC power semiconductor silicon and GaN materials such as next-generation power semiconductor data are added together to calculate the size of the market.
