2010 LED industry because LED TV industry demand, many LED chip factory greatly expanded MOCVD capacity, leading to the upper reaches of the material, such as sapphire substrate and MO Source out of stock status.
And recently had a chance to visit the LEDinside Source MO China only specializes in the production of material suppliers, Jiangsu South photoelectric materials Limited by Share Ltd vice president Lv Baoyuan. Introduce the current situation of the development of MO Source industry through Lv Fuzong, and the supply and demand situation in 2011.
Jiangsu NANDA optoelectronics, with independent technology and patented MO source suppliers
Jiangsu South photoelectric materials Limited by Share Ltd was founded in December 2000, professional production of high purity metal organic compounds with independent intellectual property rights (MO). The company's technology originated from Nanjing University, the National 863 Program of new materials MO source research and development center, the project is part of China's national plan 863. After ten years of efforts, the project has blossomed, not only can provide MO Source material for the independent Chinese LED industry, also exported to East Asia (Taiwan, South Korea and Japan), Europe, the United States and other international market.
MO source production process and entry threshold
Lu deputy general introduces the main products of the company MO Source, which stands for metal organic source, which is suitable for the metal organic source, metal organic chemical vapor deposition (MOCVD) is a kind of metal organic compound technology application, is often referred to as the MO source. The production after 5 processes, the first step is the synthesis of compounds (such as: three TMGa three methyl methyl gallium, indium TMIn etc.), the second step is to purify (to improve purity), the third step is to test the analysis, mainly to test the purity and impurity content, the fourth step for filling (inspection), the last after the completion of filling step again because the South photoelectric detection, compared to other manufacturers pay more attention to each bottle of product quality, therefore attaches great importance to the two inspection in the production process.
The purity of MO Source is the key to high quality, if not purity, oxygen impurity will lead to high quality, chip luminous intensity weakened or even not light, some impurities will cause leakage phenomenon. Therefore, the purification technology has become the main threshold for manufacturers to produce MO Source. Jiangsu South photoelectric after long efforts, now can use all of the industrial production of LED high pure MO source, such as three methyl gallium (TMGa), trimethyl indium (TMIn), three (TMAl), three methyl ethyl aluminum gallium (TEGa) and mixed with MO source, such as Mao Mg (CP2Mg) two two, a group of zinc (DMZn), two (DEZn), zinc ethyl trimethyl antimony antimony (TMSb), three (TESb), carbon tetrachloride ethyl bromide (CCl4) and four carbon (CBr4), the purity reached above 6N~6.5N (99.9999%~99.99995%). Mass production of Source MO on the production process put forward a higher degree of difficulty, so at this stage the global MO Source manufacturers are few.
MO source production process
2011 MO sources still have the opportunity to supply tight
Vice President Lu pointed out that most of the original MO Source supply chain Monopoly in the international giant hands. At this stage the global MO Source manufacturers are mostly concentrated in Europe, the United States, Japan and other countries, such as Europe's Akzo NobEL, the United States Dow Chemical (Rohm Haas), the United Kingdom SAFC, Japan's Sumitomo. MO Source is a small group of Companies in which a small part of the product. While benefiting from the 2010 MO Source large shortage of influence, Jiangsu NANDA photoelectric launched a substantial expansion of production plans to further expand its market share in Taiwan and South korea. At present, Jiangsu NANDA photoelectric production capacity of about 3-5 tons / year, the future there are plans to continue to expand production, is expected in the next few years will be expanded to 30 tons / year capacity.
For 2011 LED industry will have a chance in drastic shortage? Lv Fuzong believes that the Taiwan market is still in short supply, mainly because Taiwan manufacturers to expand production capacity, the introduction of a MOCVD machine, the machine leads to substantial growth in the MO Source on the Taiwan market supply shortage. Although South Korea's major customers for the demand for MO Source than before the stock has slowed down, but still not get a small customer. However, due to the 2011 LED backlight TV market warming, a substantial increase in the amount of LED usage, after ~4 months in March 2011 there may be MO Source second round of tight supply.
The future planning and the next phase of the challenge in Jiangsu
For the company's future planning, Jiangsu South photoelectric will cooperate with the lofty goal China national LED industry development, to do bigger and stronger, to occupy a space for one person in the world in the LED industry. Vice President Lu added, LED as a new technology, its future application will be more and more widely, accordingly to the LED industry related companies has brought opportunities and challenges, those with independent intellectual property rights of the enterprise, will prevail in the future competition, and in the fierce market competition gradually towards the benign development.
And in new applications, the company plans in a semiconductor, independent research and development of solar photovoltaic industry, has produced forward-looking products in this field. For the application of Phase Change Memory (PCM) products, the company has started to study, and a small amount of product shipments, but the mature application of the product also needs 3 - 5 years.
