Dongguan LED industrial chain strong Dongguan gallium semiconductor 1 years from ten million to one hundred million

10 million yuan to the distance of $100 million, Dongguan in the gallium semiconductor company (hereinafter referred to as gallium semiconductor) feel far, this year directed at the value of the output value of 100 million yuan, while last year's output value of only $10 million.

The 100 million yuan output value of gallium semiconductor, even in Dongguan is not much. LED industry has been included in the strategic emerging industries in Guangdong. Last year, Dongguan LED industry output exceeded 8 billion yuan. However, behind this small number, but it is the third generation of semiconductor materials in the LED industry in the industrialization of the road.

Industrial advantage

LED complete industrial chain

The latest survey shows that the Municipal Science and Technology Bureau, Dongguan LED industry has formed a relatively complete industrial chain, distribution in the upstream epitaxial wafer, the middle reaches of the chip, each link and downstream packaging, application and supporting materials, the city has 110 LED related enterprises. Gallium semiconductor is one of them.

In fact, in 2009 settled in Dongguan, gallium semiconductor, is currently the only one in the city of LED upstream substrate, epitaxial film production enterprises, its gallium nitride substrate products are third generations of semiconductor key materials. In the semiconductor gallium based in Qishi Town, as China's first professional production of GaN substrate material companies, have full right to speak in the LED high precision equipment manufacturing etc..

It is precisely because of the special status of the gallium semiconductor has been a special care". In the semiconductor gallium general manager Zhang Guoyi said, after 2009 the company set up Dongguan, the relevant departments of the city to promote the rapid industrialization of new technology products, before the company did not come, for an office, and quickly help build factories, all kinds of funds to support fast in place.

Later, in June 2009, the acquisition of a gallium semiconductor company in South Korea to absorb new technologies, and in July to spend about 40000000 yuan to import from Germany, the device used to prepare epitaxial wafers of two. August, the new research and development of new equipment in China semiconductor market. 2010, the annual sales of 10 million yuan.

"Our goal this year is 100 million yuan. "Zhang Guoyi introduced, in the semiconductor gallium with four core products, namely, Gan Gan substrate sapphire compound substrate, patterned sapphire substrate and laser stripping machine, wherein the laser stripping machine has been exported to the United states.

Technical advantage

Third generations of semiconductor ideal material

In the field of LED technology, there is such a barrier: the substrate material used in the study of gallium nitride is more, but there are only two kinds of substrates that can be used for production.

The two substrates are not the best substrate materials. In fact, the ideal substrate for gallium nitride production is gallium nitride single crystal material. However, it is very difficult to prepare gallium nitride single crystal material. Researchers have tried to produce Gan thick films on other substrates, and the gallium nitride thick film can be used as substrate for epitaxy. The advantage of this kind of Gan thick film is obvious, but the price is very expensive. Gallium nitride thick film as a substrate for semiconductor illumination is limited.

Two years ago, by the famous physicist, Chinese Academy of Sciences Gan Zizhao as leader, led by the research team led by Zhang Guoyi to overcome these problems. Zhang Guoyi is also a member of the Peking University School of physics doctoral tutor, director of the joint research center of wide bandgap semiconductor, Peking University.

Gallium semiconductor, naturally become the promotion of the gallium nitride substrate, such as the industrialization of new products, and successfully achieved large-scale production.

It is understood that in determining the cooperation with Dongguan, many high-tech talent airborne Dongguan. In the semiconductor gallium has hired Gan Zizhao as chairman of the company's Advisory Committee, Zhang Guoyi as general manager of the company, associate professor, deputy director of the Tong Yuzhen Peking University Research Center for wide band gap semiconductor company deputy general manager, associate professor of engineering at Chiba University as the research center of gallium in Qin Zhixin company in Beijing.
