Domestic MOCVD equipment assembly line is expected to reduce the cost of LED

Domestic LED (light emitting diode) epitaxial chip core equipment MOCVD (metal organic chemical vapor deposition) recently in Guangdong semiconductor manufacturing co.. In January last year, Zhao Xin Group signed a contract with the Huazhong University of Science and Technology LED epitaxial chip core equipment MOCVD, less than a year, the success of this device to the market. The general manager of Guangdong Zhaoxin Semiconductor Equipment Manufacturing Co. Gan Zhiyin said that once the domestic MOCVD equipment industry market, will enable the LED chip production investment cost is greatly reduced, to revolutionize the domestic LED industry, domestic and even foreign LED packaging product prices will be greatly decreased. Domestic LED core equipment is being broken, however, the success of domestic MOCVD equipment can be changed to extend the LED epitaxial chip core equipment market structure has yet to be tested in the market.

Equipment localization greatly reduce the cost of LED

MOCVD is the most important LED epitaxial chip production process equipment, at present, can produce the equipment in the world within the scope of the enterprise but also 3 to 5, mainly including Germany Ace (Aixtron, 70% international market share, the British Toma Schwen (ThomasSwan), was acquired by Aixtron), Viiko (Veeco, 20% the international market share), American Emcore (acquired by Veeco), Japan Dayang acid (Sanso, 7% international market share, mainly in domestic sales). Domestic LED manufacturers required equipment must be imported, and such equipment is about 15 million yuan per unit, the acquisition cost of about LED of the entire cost of the production line 2/3. Suzhou nano crystal photoelectric Co., Ltd., chairman of the Institute of Chinese Academy of Sciences, Suzhou Institute of nanotechnology, doctoral tutor Dr. Liang Bingwen said that the success of MOCVD and other key equipment localization means that LED cost reduction. At present, the equipment is relatively expensive, under normal circumstances, in the first few years, the depreciation of equipment about the entire LED chip costs about 12%-40%, so the localization of key equipment will greatly reduce the manufacturing cost of LED. Liang Bingwen said.

Secretary General of Fujian Province, the original China Optoelectronics Industry Association optical photonics Optoelectronics Industry Association branch secretary Peng Wanhua said in an interview with reporters, the current global manufacturing MOCVD epitaxial furnace equipment in the United States, Germany, Japan and South Korea, China has also developed several units of MOCVD equipment, has produced a prototype for the trial I do not know why, but no progress. "Because the MOCVD equipment is the key equipment in the development of LED industry, which plays an important role in the development of LED industry, the relevant departments of the State shall focus on the original trial of MOCVD equipment unit of talent and resources for development, investment, solve the key technology of manufacturing equipment, grasp the core technology with independent property rights, and as early as possible the localization of MOCVD production equipment. Only in this way will accelerate the development of LED industry, reduce the cost of LED related products, to achieve greater industrial development. "Peng Wanhua thinks.

With the development of technology and LED has become increasingly prominent in the green energy-saving advantages, LED is widely used in various fields, the initial technical barriers were gradually eliminated, LED development demand change rapidly, also stimulate the LED chip production equipment -- MOCVD in low cost and high performance and high productivity the direction of development.

Process and equipment is the key to promote the combination

No equipment must be on paper, no process equipment will be passive water. Vice president of Nanchang University, latticepower chief scientist Professor Jiang Fengyi in an "Chinese electronic newspaper" interview with reporters, carry out the production of MOCVD equipment to fully consider the combination of technology and equipment, the equipment and the process can be neglected. Jiang suggested that countries should not only research funded by MOCVD equipment, but also to try to use MOCVD in the development stage by the extension of production enterprises. Because in the trial process, the enterprise is not stable production, need to spend huge sums of money in accordance with the characteristics of the equipment to explore the epitaxial production process. To explore the success of the extension of the production process of human and material resources, or even more than the cost of the equipment itself.
