Power Semiconductors: A Good Policy Environment For The Development Of Upstream
Power semiconductors is weak control and strong electric running between the information-technology and advanced manufacturing as a bridge between, is an important basis for the national economy. As countries around the world increasingly urgent demand for energy saving, power semiconductor devices from traditional industries into new areas of control and 4C Energy , Rail transportation, smart grid, frequency appliances and many other industries.
Control of key technologies of foreign enterprises
? 2011 power device market in China will account for half of the world.
? Our power semiconductor production conditions and process technology to stop at the level of 90 foreign countries in the last century, the key technology lies in the hands of a few foreign companies.
Power semiconductor device is able to withstand high current and voltage of semiconductor devices, the semiconductor industry is second only to large-scale IC Another major branch. Power semiconductor devices can be divided into discrete power semiconductor devices and power integrated circuits two categories, power semiconductor discrete devices in the country also is often called the power Electronic Devices According to Beijing University professor Kang Po-bit, IGBT (insulated gate bipolar transistors), power MOS (metal – oxide – semiconductor field-effect transistors) and power FRD (fast recovery diode) is the product of the three pillars of the field, ago as the main thyristor and power bipolar transistors has been very little market share.
The role of power semiconductors and traditional industries are mainly energy-saving information. Each year, about 60% of our electricity for a variety of motor, frequency control of motor drive technology is an important means of electrical energy, saving about 20% -30% margin, while the frequency control device is used in power semiconductor. From a technical level, the last century, after the 80’s developed a new, more advanced power semiconductor devices of all power semiconductor devices about 80% while that of the previous conventional power semiconductor only less than 20% share.
From traditional applications of view, about 70% for power semiconductor Communicate , Computer, consumer electronics and automobiles so-called “4C” industry, about 30% for industrial and medical fields. Jiangsu Hongtu Micro Technology Co., Ltd. General Manager Zhao Shanqi in the “China Electronics News” interview, said a global scale, solar power, wind power generation, electric vehicles, smart grid is the power semiconductor devices and other fields of application of new hot spots.
Today, China is growing as the world’s largest power semiconductor market. From 2005 to 2008, China’s power semiconductor market average growth rate of 23%, 2008 Sell Amount is 82.18 billion yuan, preliminary estimates for 2009 semiconductor sales in China’s power has been more than 87 billion yuan. China’s power semiconductor market in the next few years will maintain growth in 2010 will reach 95.66 billion yuan in 2011 to reach 106.05 billion yuan. It is predicted that by 2011 power semiconductor sales in the Chinese market will account for 50% of the world.
Although China has become a global power semiconductor industry is an important market, but the Chinese power semiconductor device design and manufacturing capabilities to be improved, China’s power semiconductor business conditions and production technology to stop at 90 years abroad, the level of the last century The key technology is still a handful of foreign companies. Chairman of Star Semiconductor Co., Ltd. Jiaxing Shen Hua told reporters that at present China’s new IGBT power semiconductor industry in particular is still in its infancy, the lower supporting far from perfect. According to statistics, the power required for the domestic market, about 90% of semiconductors are still dependent on imports, lack of core technology will be a serious impediment to China’s emerging energy industry.
Jiangsu Hongtu Micro Technology Co., Ltd. General Manager Zhao Shanqi:
Compared with other countries, China’s power semiconductor device market is characterized by the use of devices varieties, wide application field; However, the domestic market, high-end products (such as IGBT) is basically monopolized by foreign firms, domestic product market certification period is very long, and gaining market acceptance is not high.
