Improving the innovation ability of LED manufacturing equipment in China

, a global LED industry status and development trend of at present, the world has nearly 200 companies and more than and 300 universities and research institutions engaged in GaN based LED material growth and device fabrication technology and related equipment manufacturing research and development work, in the leading level of the company are mainly in Japan, Nichia ToyotaGosei, SONY, SANYO, American CREELumileds, European OSRAM, Philip, Chinese Taiwan chip manufacturers are united, wafer, Guang Lei, GA, Guangzhou, Chan yuan Granville, packaging mainly Everlight, Dingyuan photoelectric, Baihong industry etc.. These large multinational companies more than the original patent, leading the technology trend, occupy most of the market share, of which Japan's Nichia Corporation is the world's research and production of LED's "top" unit, has been leading the other units of 2-3 research and development level of more than ten years of the GaN based LED. Nichia Corporation has a number of patents in the production of white LED phosphor materials, has been dominant in InGaN white LED chip supply, but the patent technology has been in control of internal use. Lumileds has also developed a maximum luminous power of up to 120lm white LED, the University of California solid state luminescence and display center plans to develop in 2007 200lm/W efficiency of LED. The huge market face semiconductor lighting will be formed, the world semiconductor companies and lighting companies have invested heavily into the semiconductor lighting market, the United States since 2000 to invest $500 million to implement the "national semiconductor lighting plan". The United States Department of energy predicts that by 2010, the United States will have the incandescent lamp and fluorescent lamp 55% is replaced by semiconductor lighting, at present, the world to master the technology of semiconductor lighting semiconductor company and lamp manufacturers have already have established alliances, such as the United States Japan and Germany combined HP Nichia SIEMENS, CREE, SIEMENS and the United States Germany Osbourne the United States EMCORE Lang, and GE, Japan's Toshiba and Honda jointly, which Osborn Lang and GE, is the world famous lighting manufacturing giant, general electric, PHILPS Osbourne, Lang and the world's three lighting giant, all plans to launch a large-scale commercial development, in cooperation with the semiconductor companies or mergers and acquisitions, establishment of semiconductor lighting enterprises they also pointed out that, to make the luminous efficiency of semiconductor lamp increases by 8 times in 2010, the price down to 1% now. Taiwan is the world's most important base for the production of LED, the output of more than 1/3 of global LED production, as early as the beginning of 1990s has ranked third in the world. At present, China's Taiwan LED market share has reached 28%, more than the United States, ranked second in the world LED market, more than 80% products for export, mainly exported to Korea, Japan, the United States and Europe, currently in Taiwan LED industry is mainly, high brightness and large color to the direction of development, only for LED the production of MOCVD equipment is up to more than and 200. Two, huge market demand for a broad market prospect according to CIR, the global LED market from 2004 of $3 billion 680 million, increased to $3 billion 900 million in 2005, is expected to 2007, the global LED market will reach $4 billion 700 million, among them, high brightness light-emitting diode market will account for 44% the share is expected to reach $520 million, accounting for 11% of the market share. StrategiesUnlimited according to statistics, in 2005 for mobile phone and other handheld devices LED sales growth of 3 times in the past 2 years, reaching $2 billion 28 million. Sales accounted for 51% market share, automotive sector reached $546 million, the display field sales reached $546 million, accounting for 14% of the market share, sales reached $234 million in the lighting field, traffic light field sales reached $78 million, at the same time, LED will also be in the next 10 years is now being poured into the incandescent and fluorescent lamp take the $12 billion worth of traditional lighting market. Even without considering the traditional lighting, it is also a thriving market, is expected to be high brightness LED in the global scope of a large number of sales, the biggest and fastest development of the LED market in the next 5 years will grow at an annual rate of 14%, from $3 billion 680 million in 2004 rose to $7 billion 200 million in 2009. Compared with the previous LED, gallium based high brightness LED technology has higher luminous efficiency, can produce even in daylight or outdoor use light. According to industry estimates, by 2008, the global LED application market will increase from $12 billion 500 million in 2004 to $50 billion, a huge potential market, the competition will become more intense, the Research Report of the U. S. Department of energy analysis, by 2010, the United States will have 55% of the incandescent lamp and fluorescent lamp by the semiconductor lamp replacement save electricity, up to $35 billion a year, is expected to form a semiconductor light industry $50 billion. Three, China's LED manufacturing equipment industry support the industry in the country, Taiwan and join the international giant three party, LED industry in China has a considerable scale, by the end of 2004, the country has about 3500 more than the LED of all types of enterprises, employees more than 50 people, 40 billion LED output device only / years, has formed a production, from epitaxial chip preparation to integrated device packaging applications relatively complete industrial chain, production enterprises to focus on the distribution in the Yangtze River Delta, Pearl River Delta, Jiangxi, Fujian and Bohai Bay area. According to statistics, in 2004 China's LED demand of about 24 billion, the application market reached 30 billion yuan, the total demand in 2005 was only 30 billion, the application market reached $36 billion. The main LED production has 3 aspects, is a light-emitting semiconductor epitaxial wafer, chip manufacturing and packaging, the 3 links are domestic, especially
