Rely on good policy environment, factor of production cost is low and the resources supply sufficient advantages, "eleven five" period, overseas semiconductor discretemanufacturing link device faster to transfer to china. At present, China has become the world's most important manufacturing base for semiconductor discrete devices.According to statistics, in 2005 China's semiconductor discrete devices market sizehas reached 64380000000 yuan, accounted for more than 40% of global marketshare (source: Chinese Semiconductor Association package branch). But from the level of technological development, the current domestic semiconductor discretedevice industry technical level there is still a gap with the international advanced level.In 2009 the "electronic information industry restructuring and revitalization plan" put forward clearly to improve the model of the power electronic device research and development ability, form a complete industrial system, support each other. With the development of semiconductor discrete devices domestic trends appear and try for the growth in demand for the downstream application, our discrete semiconductor devices industry contains a huge development opportunity.
