LED industry chain is not a rare insurmountable obstacles MOCVD-LED-electronics industry
LED Industry, from materials and equipment, wafer growth, Chip Manufacturing to packaging and application of the whole industrial chain, equipment, once again restricted the development of the industry's weak link. Industry experts said China's LED industry wants healthy and rapid development, be sure to key equipment, raw materials, real effort.
Upstream need to rely on imports of key equipment
LED wide range of production equipment
Almost entirely dependent on imports of key equipment
According to reports, in the LED production process requires a lot of equipment, from single-crystal sapphire substrate processing furnace, multi-line cutting, grinding and polishing equipment, to the MOCVD (metal organic chemical vapor deposition), annealing furnace, etc. equipment, to and IC Chip technology similar equipment, such as lithography, etching machines, washing machines, evaporation coating, etc., and finally to the packaging machine with a solid crystal, gold / aluminum wire bonder, sorting machines, etc., a wide range of . Which, MOCVD, plasma etching machine high-tech equipment, domestic production to rely on imports. Only a few devices made in China, such as the CLP and Technology Development Group of 45 single-wire cutting machine, multi-pasting machine, automatic wire machines, sorting machines, grinding wheel dicing, laser dicing machine, etc. have been used in the user line.
CLP Technology Group 48 Xiao-Yu Hu, vice minister of research and development center, said in an interview by the overall low level of domestic equipment manufacturing constraints, coupled with the extrusion of imported equipment and foreign patents blockade devices, domestic LED equipment (including part of the IC chip manufacturing equipment) as a whole lags behind, largely at the laboratory level, the equipment productivity, technological level, consistency, uniformity and reliability in comparison with the international advanced level there are still significant gaps. He said that in recent years, domestic research unit LED production equipment for a number of attempts made some breakthroughs in technology, such as single crystal furnace, grinding and polishing machines, but most did not use the production line. Therefore, the domestic LED device to enter mass production line is still a long way to go.
"LED industry chain in the upper reaches of the most critical equipment, the domestic is completely blank, but also imports, such as MOCVD epitaxy equipment mainly from the United States, Germany and the UK. In the middle, chip production equipment are now some companies have been able to such as etching machine, the effect can also be used, but with the foreign equipment is not small compared to the gap. "optical crystal can (Jiangxi) Co., Ltd. Wang Min, vice president, said.
To industry sources, LED devices encountered in the development process of most of the cost of equipment and imported spare parts for most products, and equipment are far lower than the price of foreign equipment, which makes the device very low profit margins. "The current large-scale LED state enterprises enjoy tax exemption for imports of equipment, which is our own R & D facilities are very unfavorable." CLP Technology Group, 45, deputy director of marketing, said Wang Haiming.
Equipment development and process should be closely
Photovoltaic equipment would be impossible to completely clone
Around to meet the needs of process development
Made equipment has been in the solar PV industry chain has played a significant role in domestic LED device is also able to compensate for LED industry chain in the missing link? Xiao-Yu Hu said, LED industry and solar energy industry has many similarities, but there are great differences between LED devices made entirely clone if the practice of photovoltaic devices is certainly not work. In all of the photovoltaic devices, and no single device such as MOCVD, as in the LED production equipment investment accounted for such a large proportion. Domestic LED device manufacturers have begun to make a breakthrough from the MOCVD equipment in order to move forward step by step process equipment Road and after-expanding, and ultimately the whole industry chain, all the equipment at home.
