Power device market in China, and the management of power | voltage regulator IC still occupy the first position in the market in the second MOSFET (metal - oxide - semiconductor field-effect transistor), high power transistor in the third, three product sales accounted for more than 80% of the overall market. IGBT (insulated gate bipolar transistor) sales was not much, but with the growing number of applications in industrial control, consumer electronics field, its market sales maintained a rapid growth of emerging power device market in China products.

　　Judging from the applications, ranked first in the field of consumer electronics sales, the industrial control residing in the second field of computer sales in the third. The three major areas of sales accounted for 68.9% of the overall market, is an important power device applications market. Meanwhile, the rapid growth in the 2007 production by virtue of the laptop, the computer field for demand exceeds the growth rate of the power devices in various fields first.

　　MOSFET market development highlights

　　2007, the Chinese market has slowed demand for power management IC. This is mainly due to the impact of the downstream machine production and inventory adjustments. With Chinese manufacturers continue to enter the LDO (low dropout linear regulator), the DC-DC (DC - DC) market, a certain extent, the decline in the price of low-end power management IC products. Under the double impact of the slowdown of the market demand and product prices fell, China power management IC market growth of 14.8% in sales in 2007, a more substantial decline than the 23.2 percent growth rate in 2006. However, even if the Power Management IC market growth slowed in 2007, China Power Management IC market growth rate is still higher than the 3.8% of the global level.

　　Power discrete devices, compared to a high-power transistors, Darlington and the low growth rate of the thyristor, MOSFET and IGBT still maintained a rapid development. MOSFET has been widely used in the motherboard, ballast, notebook computers, computer class power adapter, LCD TV and other products, by virtue of a faster growth rate of the market as well as a broad market space, MOSFET China discrete power devices market Development highlights.

　　Laptop production growth rate of more than 40% in 2007, LCD TV production growth rate of more than 70%, driven by the rapid growth of the whole production MOSFET market demand in China, but due to the overall machine production growth has stabilized, MOSFET market demand growth rate has declined compared to 2006. The MOSFET market demand in China in 2007 reached 17.12 billion, market demand amounted to 22.05 billion yuan.

　　With the huge amount of consumer power adapter, ballast and other products, the demand of the field of consumer electronics products MOSFET ranked the first in the field of the MOSFET in the computer's motherboard, laptop, computer classes adapter, widely used in products such as liquid crystal display, the computer field after the consumer electronics market demand. Network communications, industrial control, automotive electronics and power equipment in the field, the demand for the MOSFET in the third to six. Motherboard applications use low voltage high current MOSFET products, the relatively high price of their products. Relative to the relatively large proportion of the low voltage and small current computer applications in the field of consumer electronics products, the prices of their products is relatively low. Affected, the computer field MOSFET needs amount exceeds the field of consumer electronics at a field of consumer electronics behind in the third place, while the field of industrial control demand amount.

　　Competitiveness of local enterprises should be improved

　　Occupies a relatively large dominance in the power device market in China, the European and American firms, in 2007, ranked in the top 10 power device manufacturers, and European and American firms accounted for 9 seats. The top 10 manufacturers, Texas Instruments | Instruments and National Semiconductor is mainly focused on the production of power management IC products, Wei Xu has a strong market competitiveness of the MOSFET breakdown products market.

　　Fairchild, STMicroelectronics, ON enterprise product line covers a wide range of products, including power discrete devices and power management ICs. The current point of view, these enterprise product quality, strong technical strength and leading position in the power device market.

　　In recent years, China Taiwan enterprises gradually into the production of power management ICs and power devices products, these companies by virtue of lower product prices in the low-end market has been relatively rapid development. Li Guoqi odd, the Truswell advanced, ANPEC AME caused by new, Peiheng SG China Taiwan manufacturers representative.

　　Local enterprises in recent years, there have been a number of enterprises engaged in the production of power management ICs, these enterprises to design enterprise products are mainly concentrated in the LDO and DC-DC. MOSFET, IGBT and other high-end power discrete products, and mainland China at this stage is also a lack of strength of the IDM (vertically integrated) enterprise. But with the power device manufacturers such as Fairchild part MOSFET foundry production on the mainland region to do, the mainland areas MOSFET foundry services achieved a certain development. Currently the CSMC 吉林麦吉柯, Shanghai advanced, Hua Hong NEC during MOSFET products foundry services. In these enterprises China Hong NEC and Advanced Semiconductor 8-inch line MOSFET capacity foundry services CSMC 6-inch line MOSFET foundry services, 吉林麦吉柯 MOSFET products on behalf of the 5-inch line work services. In the next few years, Jilin Sino micro, Tianjin Central will also enter MOSFET market.

　　In summary, the European, American and Japanese companies in the power device market by virtue of the excellent quality of products in a leading position, China Taiwan enterprises by virtue of a good cost-effective products in the market has been rapid development of the Chinese mainland enterprises in China power devices on the market competitiveness is still weak, and the strength of enterprises should be improved.

　　MOSFET products towards high-end process

　　With the rapid development of the field of consumer electronics, computer, power device products also showed a trend of rapid growth, high reliability, energy saving, high performance, small size also makes the product miniaturization, RoHs compliant power devices future trends. Enhance packaging process is an effective way to improve MOSFET performance and stability. With the rapid increase of the needs of small, thin, faster, better heat dissipation and more reliable performance portable applications MOSFET devices on the market, the world's leading MOSFET manufacturers IR, ON, Infineon and so constantly upgrade package technology to improve the level of heat from the device.

　　MOSFET technology can be broadly divided into the plane and trench two categories. Trench MOSFET technology for low-voltage MOSFET products, market acceptance and market trends. Planar technology still has some potential for development in the high-voltage MOSFET market. Future, the technology of the plane containing the high-end technology will be one of the trends of the high-voltage MOSFET.
