In the international context of energy conservation and environmental protection, China has introduced a series of policies to increase the support of the LED industry, and the industry prospects are beyond doubt. However, the core automation equipment is still relatively backward, especially for epitaxial and chip manufacturing equipment. The localization process of MOCVD and other equipment determines whether the future LED industry in China can develop healthily, continuously and rapidly.
The international short-term training course of MOCVD technology reveals the latest international technology and development trend. The research and development ideas and hotspots of international advanced enterprises may provide some ideas for China's equipment materials to break through the bottleneck of localization.
MOCVD shipments surged in three major areas
The rapid development of China's LED industry continues to drive the expansion of MOCVD equipment. It is reported that the current domestic enterprises MOCVD reached 135 units, this year's equipment plans to increase more than 100 units, the chip production capacity growth rate is expected to exceed 60%. In addition, MOCVD procurement plans are constantly appearing in Taiwan, Europe, and Japan. Dr. Michael Heuken of AIXTRON in Germany believes that the three major areas of large-size LED backlighting, automotive electronics and indoor and outdoor lighting have contributed the most to the growth of MOCVD.
4-inch MOCVD equipment will become the mainstream
Although considering the cost, 2-inch MOVCD equipment is still the main production line in China (including Taiwan), but Japan's Namiki Precision Jewel company shufan cheng pointed out that the 4-inch MOCVD equipment is developing rapidly and will become the mainstream of the market. The 6-inch blue LED chip, in the structure of the 6x6-inch AIX 2800G4 HT MOCVD reactor, yields an increase of about 30% (compared to the traditional 42x2-inch architecture), which not only has better uniformity, but also reduces edge effects. ). However, at this stage, most of the difficulties still lie in the high price of 6-inch substrates and the challenges of epitaxial wafer cutting technology.
Industrialization level and patent barriers test China's equipment industry
At present, the research and development of domestic MOCVD equipment is still in the stage of digestion and absorption, and foreign mainstream commercial models have established strict patent protection, such as AIXTRON's Planetary Reactor reactor, THOMAS SAWN's CCS (Close Coupled Showerhead Reactor) reactor, VEECO's Turbo Disk reactor and Japan SANSO double/multiple beam (TF) reactor are their own unique patented technologies. The domestic industrialization of MOCVD equipment faces the test of patent barriers.
At present, China is in a critical period of expanding domestic demand, accelerating infrastructure construction and industrial transformation and upgrading, and has huge market demand for advanced equipment. The financial crisis has accelerated the adjustment of the world industrial structure and provided opportunities for China to participate in industrial division of labor. In the field of LED equipment, in order to speed up the localization process, in addition to the state's policy to increase the support of equipment production, equipment manufacturers also need to rely on enterprises with strong mechanical processing and system design capabilities to support.
