Discrete devices: automotive and lighting market highlights the importance of expansion packaging

Discretedevices technology innovation can not ignore the actual market demand, while improving the quality of the device needs not only the advanced manufacturing process chip, improved packaging technology is an important way to enhance product quality.

From market applications, consumer electronics, computer and network communication is the three largest application market of traditional discrete devices, and in recent years, automotive electronics and electronic lighting in the field of discrete devices market is also growing rapidly. At present, although the discrete device has a certain industrial scale, but its development and the needs of the domestic market is still there is a big gap between the rapid development of China, discrete devices industry must be based on continuous technological innovation as the driving force.

Discrete devices industry faces opportunities

The rapid development of electronic information industry and machine manufacturing industry, led the development of the semiconductor industry. As an important part of semiconductor industry, discrete devices have their own characteristics. The development of integrated circuit is very fast, the function is more and more strong, but semiconductor discrete devices will continue to exist in many areas, development. Just as human beings have airplanes, they still need trains and cars. CLP Technology Group thirteen science and Technology Commission Director Li Songfa explained to reporters.

Discrete devices in high power and high voltage, large current and other traditional applications will continue to play its irreplaceable role in many emerging applications will also play an indispensable role. Hangzhou Silan microelectronics division of Limited by Share Ltd general manager devices division Tang Xuemin said in an interview: "the market volume steadily, driven by the amount of discrete devices continues to expand, with the development of the integrated circuit technology, integrated many peripheral devices at the same time, but also to promote the development of new functional devices. For example, with the development of CMOS (complementary metal oxide semiconductor) technology to deep sub micron, higher requirements for ESD (electrostatic discharge) protection devices have been put forward, which makes the use of the device increase dramatically. In addition, because the power products emphasize green, environmental protection and energy saving, many power electronic devices has achieved great development, such as high voltage MOS (metal oxide semiconductor) power transistor in the power field has been widely used, IGBT (insulated gate bipolar transistor) in motor drives has display skills to the full. "

With device performance breakthrough, discrete devices will also develop many new applications. "For example, with decreasing constantly improve the technical performance of the blue chip high brightness and cost, large full-color LED (light emitting diode) display to a large number of applications, at the same time, LED in the outdoor landscape lighting, LCD (liquid crystal display) backlight, special lighting and other fields have achieved great development. "Xuemin added soup.

Tianjin Zhonghuan semiconductor Limited by Share Ltd general manager Shen Haoping to the "Chinese electronic newspaper" reporter expressed similar views, he said: "the two aspects of the energy and environment pressure, power electronics in recent years has been rapid growth, especially in emerging industrial countries, because of the relatively low efficiency of energy use. Power electronic products will have greater development space. From the point of view of consumer electronics, almost all portable products are the bottleneck of the battery, so power management can also be said to be an eternal topic. In addition, due to the characteristics of a large number of discrete devices with small batch, multi species, multi standard, so it is difficult to monopolize the international big manufacturers. "We can see that China's semiconductor discrete devices enterprises are facing good opportunities for development.

Technology innovation should be close to the market demand

After decades of development, China discrete device production enterprises in the middle of discrete devices has completely mastered the production technology, the formation of a certain scale of production, has achieved obvious to people results; however, in some areas, a large amount of emerging market products, to achieve a breakthrough with the international giants have failed a relatively large gap, some performance requirements (such as accuracy, reliability etc.) high product is difficult to meet the needs of the market. In addition, the local manufacturers of product quality has not yet reached the first-class level, it is difficult to be used by world-class manufacturers. Therefore, it is urgent to strengthen R & D efforts, promote technological innovation and improve product quality.

However, Shen Haoping also pointed out that the technology is one of the factors of production, but also a means to meet the demand, so we can not be separated from the product market and isolated about technology, China semiconductor companies in the importance of technology research and development also can not ignore the needs of the market. In addition to central Tianjin will maintain the existing products in the leading position in the market competition, will also use the new chip production line, dedicated to VDMOS (vertical double diffused MOS device) and IGBT power semiconductor devices in the field of research and development and production.

Tang Xuemin believes that technology upgrade is a gradual systematic project, can not expect overnight to catch up with international companies, how to improve the basis of the existing technology level of product quality and improve product consistency is Chinese discrete device production enterprises focus. After 2003 Silan first chip production line put into production in 2004, began the development of semiconductor discrete devices, has now launched a switching diode, zener diode, Schottky tube, high voltage VDMOS power transistor, transient voltage suppression diode (TVS), ESD protection tube and fast recovery
