Sunday, July 31st, 2011
Since 2010, the market of Chinese integrated circuit steps into the new round of growth stage, but the development speed of the market will not reproduce the high growth situation several years ago, increase the theme that will become development of market of Chinese integrated circuit in future steadily. The development speed of market of Chinese integrated circuit in the following 3 years will keep above 10%. So, Chinese integrated circuit material and apparatus enterprise, should seize the opportunity, innovate hard, break through to some extent in key material and apparatus, meet China’s market demand.
According to the report of SEMI, the market of semi-conductive apparatus will be 2,240 million dollars in China in 2010, it is estimated it was 2,640 million dollars in 2011. If calculate, by 2015, China’s semi-conductive apparatus market scale will reach 30 billion yuan according to such a growth rate. The insider analyzes, ” 12 five ” During this time, as China continues strengthening the new developing industrial policy support of strategy, the semi-conductive apparatus trade will welcome the rare historical opportunity for development. ” 02″ Development of new industry such as the support of the special project of great science and technology, new energy, new material and demand for the discrete device of having a large capacity and a wide range are heightened, it is the semiconductor material and further development of enterprise of the apparatus that have created the good market opportunity.
The expert analyzes, because of stimulating the government subsidy and the new application demand one is constant and surging, if the LCD TV is in a poor light and common lighted, from 2009 to 2014, China LED market will double, it is 12.8% to compound the average annual growth rate. Many kinds of apparatuses that the power semiconductor is used in electrical home appliances, computer, car and railway,etc. field extensively. Because apparatus expected to expand, popularize application the, and apparatus these allocate proportion of power semiconductor, can rise too, so, the market of power semiconductor will be expected to increase steadily in the future. It is estimated the market scale of the power semiconductor will reach 36,800 million dollars in 2013. Should there is good harvest in these fields in equipment and materials enterprises.
However, the actual conditions are that China’s semi-conductive apparatus and material enterprise’s comprehensive strength are also relatively weak at present, still need energetical support of the government and could be developed. For this reason, the insider calls upon, the country should research and develop semi-conductive apparatus and material enterprise for the support on policy with industrialization. To semiconductor material industry, at present, the customs tariff of importing polycrystalline silicon is 2%, and it is duty-free to import the silicon dice; It is the important production auxiliary material of semi-conductive enterprise that quartz crucible, transportation gift box, silicon dice polish some materials such as cloth, and because of the technological reason, China does not have a manufacturing enterprise at present, has to rely on import, but not classified it as the semiconductor in the customs tariff clearly specializedly at present, just return and list in ordinary plastic products and other industrial blown glass, it is high to import the tax rate. This leads to the fact Chinese silicon dice enterprises are great in consumption, the tax bearing is large, are unfavorable to competing with semi-conductive enterprises of foreign countries. Propose adjusting the tentative tax rate of imports and exports, revise these policies unfavorable to trade development as soon as possible. In addition, the country should also support several typical enterprises especially, rely on their leading role to spur the development of the whole basic industry.
As semiconductor material and apparatus enterprise, should work in concert, pay close attention to the turn of the market in real time, accelerate product structure and adjust the paces, strengthen the input of research and development, accelerate advanced personnel training and introduce, further improve the innovative system taking enterprise as body, improve independent innovation ability in a more cost-effective manner, concentrate on investing and solving critical, generality, basic problem with definite resources, make comprehensive policy and measure, making China’s semi-conductive apparatus and material industry steady, fast development together.
