At present, semiconductor discrete devices have not enjoyed the preferential policies like the integrated circuit industry, which is not conducive to the continuous development of discrete devices. Chinese discrete device companies must persist in finding ways to solve difficulties in scientific development and take a positive attitude to meet the bright future of Chinese semiconductors.
Although the development of integrated circuits has led to the integration of some devices into integrated circuits, discrete devices remain an important part of semiconductor products due to the particularity of discrete devices. For decades, semiconductor discrete devices have continued to evolve in accordance with the laws of their own development. Although the sales of discrete devices accounted for a year-on-year decline in the total sales of semiconductors in the world, the annual sales of discrete devices in the world semiconductor market continued to grow steadily. The same is true for the development of domestic semiconductor discrete devices, which is growing at a double-digit rate every year, which is higher than the world's growth level. It can be seen that semiconductor discrete devices still have a lot of room for development.
Photodiode sales growth fastest
In 2007, the growth of the world semiconductor industry slowed down, but the Chinese discrete device market continued to grow steadily and continuously on the basis of 2006, consolidating its position as the world's largest discrete device market.
From the regional structure of the domestic discrete device market, the Pearl River Delta region is still the largest regional market, and the Yangtze River Delta is the region with the fastest growth in total volume in the regional markets. The two regions are basically equal. In addition to the above two regions, the Beijing-Tianjin-Bohai Sea is also an important regional market for domestic discrete devices, and other regions are also emerging.
From the current market application structure of discrete device products in China, its application fields cover consumer electronics, computers and peripherals, network communications, electronic equipment and instrumentation, automotive electronics, LED display and electronic lighting. In the market application structure, consumer electronics, computers and peripherals and network communication are still the three major applications. Computer and peripheral products are still the largest demand areas in the entire discrete device market. Automotive electronics, electronic lighting, industrial automation, instrumentation, medical electronics, electronic display 3G communication and energy saving are the hotspots of the future semiconductor discrete device market. Driven by these hotspots, power semiconductor devices (including bipolar and MOS) The market for optoelectronic devices (especially high-brightness LEDs), RF and microwave devices, power Schottky diodes and Hall devices is expected to grow significantly.
In the current product structure of the discrete device market in China, among the four major categories of diodes, transistors, power transistors, and optoelectronic devices, sales of photodiodes have grown most rapidly. Power transistors are the largest sales products in the domestic discrete device market, and the market growth of diodes and transistors is relatively stable.
Packaging technology is also one of the innovation fields of discrete devices. Due to the continuous advancement of chip manufacturing technology, the die area is greatly reduced, and the customer's requirements for package size are getting smaller and smaller. Domestic Changjiang Electronics and other enterprises have mastered the ultra-fine package technology of extreme size. Great progress has been made in terms of product volume and reliability.
Three applications drive the discrete device market
Driven by the rapid growth of the automobile manufacturing industry, China's automotive electronics industry is growing at the same time. It is expected that the demand for discrete devices in the automotive electronics field will grow at an average annual rate of 28.5% in the next five years. Automotive electronics is becoming an important demand area for discrete device products in China.
The demand for discrete devices in the field of lighting is mainly reflected in energy-saving lamps. In recent years, China's energy-saving lamps have developed rapidly, and in addition to energy-saving lamps, electronic ballasts are also the main products with greater demand. Driven by the increase in output of these products, the demand for discrete device products in the lighting sector will grow at an average annual rate of 28.2%, making it the second fastest growing market segment.
In the next four years, with the issuance of domestic 3G licenses, 3G network construction and wireless communication applications, the demand for 3G central office and terminal equipment, wireless receiving and transmitting, etc. will grow rapidly, which will directly drive domestic communication equipment manufacturing. The development and drive for the growth of demand for various discrete device products. Driven by this, it is expected that the demand for discrete devices in the field of domestic network communication and RFID identification technology will reach 16.3% per year in the next four years, which will become the third largest growth point of the overall market.
From the medium and long-term trend, although the domestic discrete device market will maintain a stable growth trend in the next few years, both the sales volume and the average annual compound growth rate of sales have slowed down.
