Tiantong shares a major breakthrough in LED sapphire substrate technology

The reporter learned from Tiantong that since the company entered the LED industry in 2010, the company has been concentrating on Changjing technology innovation. It has made a major breakthrough recently, and has overcome the core bottleneck of the current crystal process and equipment technology, and realized the crystal growth process and equipment. The more reasonable fusion of technology has reached the international advanced level.

According to reports, since the investment in the sapphire industry, the company has been committed to re-innovation based on the introduction of foreign advanced crystal technology. After more than two years of hard work, the company has made major innovations in crystal growth and crystal growth equipment technology, achieved a major breakthrough in crystal growth technology, and has overcome the core bottleneck problems of current crystal growth process and equipment technology, realizing the growth of crystal growth technology and equipment technology. The more reasonable fusion. The results of the trial production show that the crystal growth technology is stable, and the crystal quality consistency is good. The qualified rate of the 80 kg crystal opening furnace is more than 85%, and it can produce high-quality, large kilogram-level sapphire crystals in large quantities and in a stable manner. The crystals produced by the company have the characteristics of good single crystallinity, low dislocation density and good light transmission, and have reached the advanced level of similar foreign products. The crystals are suitable for making large-size (6-12 inch) sapphire parts, and the 80kg crystals are significantly more efficient than the domestic and foreign counterparts. At present, the company is actively developing more high-quality, low-cost sapphire crystals to further increase its core competitiveness.

Tiantong Co., Ltd. official told reporters that in the processing of the substrate, the company's product positioning for the high-end substrate 4,6 inches. The company has introduced internationally advanced cutting and polishing production lines with core competitiveness in key processes such as large-size substrate slicing, grinding, polishing and cleaning. At the same time, the company has established a high standard of clean workshops, with ten, hundred, one thousand, and 10,000 production workshops of nearly 8,000 square meters, which fully guarantees the high quality of product processing. In the production process, it is equipped with the most advanced high-precision testing equipment in the industry and adopts SPC quality monitoring system. An annual production capacity of 4-inch 600,000 substrate production lines has been established. It has reached international advanced level in the control of various technical indicators such as TTV, BOW, SORI, and LTV, and has good consistency and stability. Japan, Taiwan and other well-known manufacturers of products to send samples identified, there are already domestic extension and window manufacturers formally bulk orders.

It is understood that Tiantong shares began to enter into the LED field in the first half of 2010. In August 2011, the company increased investment in LED and other new energy industries and implemented an annual output of 600,000 4-inch LDE sapphire substrate material technological transformation projects. In September this year, the company issued a non-public offering plan and changed the project to "a yearly output of 1.15 million 4-inch LED sapphire substrate material technological transformation project." The project mainly produces the key upstream product in the LED industry chain, sapphire substrate material. The production process of sapphire substrate material is a very high technological content in the entire LED industry chain, especially the growth and large size of large-kilogram grade sapphire crystals. The processing of substrates involves a large number of high-tech equipment and technologies, but at present, the growth of sapphire crystals and the processing level of substrates in China are relatively weak.

According to industry insiders, since the beginning of 2012, the upstream LED industry is in a process of gradual recovery. Statistics show that the current price of LED sapphire substrates has bottomed out, and it is expected that prices will enter a recovery channel in the future, especially if the size is more than 4 inches. The size of LED sapphire substrate materials, a few domestic companies mastering the production technology of large-size sapphire substrate materials are expected to usher in development opportunities.
