Seize the opportunity of developing the western region to develop semiconductor silicon materials


T price of only 40 million, the price of polished silicon wafers up to 350 per ton million,[link widoczny dla zalogowanych], an increase of 8.75 times the obvious benefits. China's four best semiconductor materials companies to the development boom in the West, the full use of the development of western countries to grant preferential treatment to 1999 Table 31 992 different diameter wafers in the world market changes than t f-inch f% 199219941995199619981999 『varieties, 435281297_36.552727221813.611.863438434032.530.7847233345949.2 Design Research Institute in close collaboration with scientists, after nearly three years of efforts, with our own intellectual property rights of new technology polysilicon production lines have been built and put into operation. Only a few Western countries to master the new technology of advanced polysilicon production - improved Siemens process. We have the basic grasp of policy, make full use of Western personnel, grasp the pulse of western development, the development of new projects for monocrystalline silicon, polycrystalline silicon to silicon but can not speak to adjust the development and the development of other semiconductor-related materials or other project. 2. Playing in the product specifications from small diameter crystal phase to the development of large diameter. The next step is simply to maintain the production of small diameter or large diameter gradually to the development of two terms from the following: First, the development trend of silicon . Since the advent of integrated circuit technology since its hair is not economical. As the world's leading company dedicated to large-diameter silicon wafer production, no intention to take into account the small-diameter silicon wafer, resulting in the world market, especially in North America and Europe, there have been small-diameter silicon wafers atlas 4 ■ f the global small-diameter unit: million square inches, Mu 1998199920O02001 varieties (inches r 4321324335304559759961357161427155317451769 Total 2345247626932644 development very quickly, less than 3 years there will be a new generation of products, specifications and quality of silicon also made the corresponding request. the proportion of small-diameter silicon wafer demand is decreasing year by year, large-diameter silicon wafer demand ratio in the market growing. both large and small diameter silicon wafers, in particular, large-diameter silicon wafers, integrated circuits, micro-machining of their increasingly demanding quality standards. In recent years the world's silicon the market according to the different diameter wafers of area changes in the composition shown in Table 3. Second, the life of small-diameter silicon wafers. small-diameter silicon product cycle passed its peak, but a global perspective, from 1998 ~ 20o1 years are in the annual demand of about 2.5 billion square inches, is expected to 2oo0 years will maintain this demand ( see Table 4), the changes will not be too great. This is because the current use of small diameter silicon integrated circuits and discrete devices factory, all is almost impossible to use large diameter silicon wafers modified, will long continue to run down. On the other hand, manufacturing, small-scale integrated circuits of the small diameter of large diameter silicon wafers can not be replaced,[link widoczny dla zalogowanych], but also 12 shortage is expected this situation to continue. two points from the above analysis. small-diameter silicon wafer market in the near future there is a certain capacity. but the world is the general trend of the semiconductor industry is the development of small diameter to large diameter. Only large companies with international well-known, the introduction of mature technology to build large-diameter silicon wafer plant, is clearly a correct and fast development. 3. in the production scale of economies of scale to go on the road. semiconductor silicon materials industry is a high input, high-return industry. As mentioned earlier, more needed for the production of semiconductor silicon materials - silicon and semiconductor silicon material of the final product - 350 times the value of polished silicon wafers. The value of the products is very high,[link widoczny dla zalogowanych],, but also for the integrated circuit industry, supporting the high-tech industries, therefore , both at home and abroad have invested in this industry. Although the world 30 wafer manufacturing company,[link widoczny dla zalogowanych], but in the product scale, five multinational company has a 3 '0% of production capacity, control 76% market share. the remaining 24% market share divided by 25 companies, each company an average of less than 1% market share. the domestic production of the global silicon wafer industry Minimal impact, mainly small scale. China joined WTO, the domestic economy with international standards, small-scale operation at greater risk. only a certain size, can resist all kinds of risks. this world, the opportunities and challenges coexist, the question before us is how to play to our existing strengths, make an inventory of existing assets, increasing investment,[link widoczny dla zalogowanych], take advantage of favorable conditions for developing the western region and accelerate the pace of development, achieve economies of scale and reduce the gap with the international advanced level. mouth Nonferrous Metals Industry) 20OO s 』O of
