From the electrical to optical: Domestic LED chip needs to be done

"Now more and more well done, very competitive, the current profit is basically guaranteed. In particular, the LED of some private enterprise, keep the prices down kept at a very ruthless." Wang worked at a Japanese LED chip manufacturing equipment suppliers, Turning to the current LED device market, Wang seems quite depressed.

Of course, the upstream equipment prices continue to fall makes the LED chip manufacturing, and downstream LED application industry gets more profit. However, most domestic companies are not substrates LED chip with a comprehensive intellectual property system, particularly in the application of a wide range of high power LED lighting market, the domestic share of the chip is not high.

Dongguan Branch Lei must Digital Optical Technology Co., Ltd. mainly produce high power LED lighting products, Assistant Managing Director Zhu division? Told reporters: "Normally we use only imported brands of chips. Of course, sometimes the owner will be according to the requirements of domestic use LED chips. but according to our experience, most of the domestic high-power LED chips are unable to meet customer demand, or even can not our own testing. Therefore, we do not want to use domestically produced chips. "

Data show that the global market LED chip substrate mainstream technology manufacturing technology and silicon carbide substrate sapphire technology, they belong to Japan and the United States Cree Nichia Corporation. Most chip manufacturers in China to use Nichia's sapphire substrate technology, but need to pay a lot of money to the Japanese Nichia patent fees.

However, born out of the Nanchang University in Jiangxi Province, Crystal Optical Co., Ltd. is able to break this monopoly. Crystal silicon substrate to photoelectric current GaN LED technology has the crystal to optical Min, executive vice president told reporters: "silicon substrate LED chips have many advantages, an original intellectual property, in the international market without international patent restrictions; antistatic performance, long life; silicon substrate LED chips down electrode, single-wire vertical structure, reducing the cost of follow-up package. "

In fact, in addition to the other benefits, the most direct silicon substrate technology advantage is cost. Optical crystal to a staff member told reporters, "We are sapphire and silicon carbide compared to the greatest advantage is the cost, the cost of silicon substrate itself is very low, coupled with production technology advantage, our costs are far less than sapphire and SiC substrate LED chips. "

Although the technology leader, but the results of laboratory and plant products are still worlds apart. According to report, the current optical crystal can yield high-power light chip is still not high. Crystal to crystal and optical shares Lighting Co., Ltd. of Jiangxi, a staff member told reporters: "Our power to buy U.S. lighting products are part of the Cree's products because grain photoelectric yield can not."

It is reported that optical crystal can be as early as 2006, had already started to silicon substrate of LED chip industry attempts, but only until May 2008 to achieve mass production of LED chips. At present, the crystal to optical LED chips production capacity nearly 10 billion, about 80% overall yield. The crystal to optical staff told reporters: "We will enter before the end of the field of LED chip packaging, an extension to the downstream."

According to State Lighting R & D and Industry Alliance statistics, China's LED chip production in 2008 increased 26% to 1.9 billion; LED packaging production value reached 185 billion, representing growth of 10% in 2007; in 2008 China's output has more than 450 applications billion. Some analysts pointed out that although most of the enterprises in China do not have the core LED technology, but as the market rapidly enlarged in the next LED industry will continue to maintain a certain cycles.
