With the development of energy-efficient appliances, smart grid, high-speed rails, new-energy vehicles and photovoltaic power generation etc., China is seeing rapidly grown demand for 5-inch & 6-inch thyristors, IGCTs and IGBTs. Among them, business circles pay high attention to IGBT due to its wide application and seldom local production.
China’s IGBT market size approximated USD870 million in 2011; and the sale is expected to rise to USD1.49 billion at home in 2015, presenting a CAGR of 14%.
Owing to the state-of-the-art technologies of foreign corporations such as Infineon, Fuji Electric, Mitsubishi Electric, and so forth, Chinese IGBT market is almost dominated by producers from Europe, the United States and Japan at present. Global leading players have started to develop the 7th generation technology, while local counterparts still rest on the 4th-generation technology. Local manufacturers didn’t begin IGBT production until recent years, and their technological levels remain backward. Yet, they enjoy advantages in customizing products and lowering cost although their overall strengths lag far behind foreign firms; and local enterprises can be found in all links of IGBT production chain.
Considering chip design, local enterprises comprise Keda Semiconductor and Wuxi Phoenix Semiconductor, which have realized small-scale production of low-power (600V) and medium-power (1,200V) IGBTs; with their products mainly applied in electromagnetic ovens. Xi’an Power Electronics Research Institute and Shanghai CNR Yongdian Electronics Co., Ltd. have made breakthroughs in the design of medium- and high-power IGBTs which currently remain at the stage of experimental application.
As far as chip manufacturing is concerned, among local enterprises, power semiconductor producers like Tianjin Zhonghuan Semiconductor, Advanced Semiconductor Manufacturing Corp., Sino-MicroElectronics, CSMC Technologies Corporation and Hua Hong NEC etc. have realized mass-production of 1,200V IGBTs. China’s enterprises also have made breakthroughs in the development of 1,700V & 3,300V IGBT samples. In 2011, CSR Times Electric started IGBT industrialization project which will annually produce 120,000 8-inch IGBT chips and 1 million IGBT modules. The Project is expected to start production in 2014, with product grades varying from 600V to 6,500V.
In terms of module packaging, around 11 local enterprises including Jiaxing Starpower Semiconductor, Jiangsu Macmic Science & Technology Co., Ltd., Nanjing Silvermicro Electronics and Shenzhen BYD Microelectronics etc. have accomplished mass-production or small-scale production. Local enterprises purchase chips produced by INFINEON and SEMIKRON etc. for module packaging; and their products are mainly used in electric welders, electromagnetic ovens, UPS and control of motors.
