It is estimated that there is a tight supply of silicon raw materials in 2007. The demand of solar energy polycrystalline silicon will be near 20,000 tons in 2007, up by 43.50% year-on-year. Abiding by 10% industrial growth rate, the semiconductor industry will demand polycrystalline silicon 25,000 tons, but the world's total supply stands at only 36,000 tons in 2007, indicating a gap of about 90,000 tons.

China power devices market still kept fast growth in 2006, the sales revenue amounted to RMB67.3 billion, up by 24.4% compared to 2005. In 2006, the sales income of power discrete devices including MOSFET, IGBT, high power transistor, Darlington transistor and thyristor was up to RMB34.32 billion, taking 51.0% of the whole market. Besides, the average annual growth rate of power devices market will be 21.5% in next five years. By 2010, the market size will arrive at RMB85.176 billion.
