Zhongmeijing successfully developed the largest sapphire crystal in Taiwan
According to Taiwan media reports, Xu Xiulan, general manager of China-US Crystal, announced on the 21st that the company has successfully developed the largest sapphire crystal in Taiwan. The crystal is 12 inches in diameter and weighs 90Kg. It is the world's largest sapphire. One of the crystal production sizes, Xu Xiulan said that the self-sufficiency rate of the company's target in this year's crystal sapphire crystal rods can reach 50%.
Xu Xiulan said that the successful development of the sapphire crystal rod can not only be used by the current 2" sapphire wafers of Taiwan's LED industry, but also more profitable for 4" and 6" applications, not only showing the development and manufacturing capabilities of Zhongmeijing. It has entered the level of international big factories, and it is also a major progress of the domestic LED optoelectronic industry towards a more highly independent.
The large sapphire crystal successfully developed by Zhongmeijing is grown by the self-developed modified sapphire single crystal growth method, which can effectively control the crystal diameter. Compared with the traditional KY crystal, it has a competitive advantage in utilization. The 90Kg sapphire crystal can be drilled out of a two-inch sapphire crystal column of about 4000mm, which is about three times higher than the current 30Kg KY crystal on the market.
Xu Xiulan said that in 2010, Sino-American sapphire substrate accounted for only 2-3% of the revenue. This year, the production capacity of sapphire substrate will increase from 60,000 to 180,000, accounting for 5%, and the Sino-US crystal sapphire crystal can be produced. 2 million mm level.
Xu Xiulan said that China and the United States produced the first 6-inch solar crystal rod in 2000. At present, the solar silicon wafer revenue is nearly 17 billion yuan. In the next 30 years, the most important business unit of Zhongmeijing is the sapphire crystal rod. .
Xu Xiulan said that the sapphire crystal rod is a compound crystal, which is more difficult than the long crystal of semiconductor silicon. In fact, Zhongmeijing has been successfully grown in Q4 last year, and the density is very high. Zhongmeijing will be domestically available from Changjing and sliced. Manufacturers polishing to high-brightness patterned sapphire substrates.
The sapphire crystal rod is out of stock in 2010, and the price has soared. Xu Xiulan said that the price of 1mm sapphire base rod is only 5 dollars in 2009, and it has reached 25 dollars by the end of 2010. There are two sapphire crystal rods in China and the United States. The reason is that one can't buy the ingot when the economy is good. The second reason is that under the self-supplied crystal rod, Zhongmeijing will have more price tolerance.
According to the current price of sapphire substrates, the price of a 2-inch product is about $30, and that of a 4-inch is more than $100.
