Solar Silicon Valley Electronic Science and Technology Co., Ltd. was founded in 2005. Solar Silicon Valley Electronic Science And Technology Co., Ltd is a subsidiary company of Jinglong Industry and Commerce Group Co., Ltd. (). We lie in the Yanjiao Economic & Technology Development Zone of East Beijing. We were invested RMB0.5 billion. We occupy an area of 240mu. Solar Silicon Valley Electronic Science And Technology Co., Ltd is a high-tech corporation manufacturing monocrystalline silicon ingots, wafers, and quartz crucibles. At present, Solar Silicon Valley has 5 wafer processing workshops. Three workshops have been formally put into production, with the world most advanced cutting, grinding and cleaning equipment, such as 61 sets of the most advanced multi-wire-saws, 2 sets of notching machines, 2 sets of NTC machines of slabing square ingots, and German RENA cleaning lines.We can produce 3-25monocrystal round wafers and square wafers, and the output is 75 million pieces every year. Our products are widely used for the solar energy power generating, semiconductor devices and IC modules. Our products are sold to many countries such as the Netherlands, Japan, and America, and have enjoyed a good reputation in the international PV industry. Quartz crucible is the basic essential material for pulling the large diameter silicon, and developing the solar-class large-scale integrated circuit. Adopting the United States Unimin quartz sands, the Arc Quartz Crucible production method is the world most advanced technology. We have 8 production lines of quartz crucibles, and have become the biggest factory in China. We mainly produce 16-28electric arc quartz crucibles, sold to Europe and Asia. The annual output is 70 thousand pieces. The production value of Solar Silicon Valley was RMB0.65 billion in 2006. The profit and tax was RMB0.15 billion, and the tax turned in was RMB15 million. We have become a strength pillar of the economic development of Yanjiao and Sanhe. The production value of Solar Silicon Valley was RMB1 billion in 2007. The profit and tax was RMB0.33 billion, and the tax
