Zhongmei Jing said that the currently produced sapphire in the market adopts KY method crystal growth and crystal growth along the A axis, but the LED substrate application axis is C axis, the crystal must be processed again, the overall utilization rate is only 30%. . The C-axis sapphire single crystal straight pull technology developed by Sino-US Blue Crystal allows the crystal to grow directly along the C axis without the need for drilling. Therefore, the crystal utilization rate can be greatly increased from the 30% of the traditional long crystal method. Up to 70% or more, in addition to the difference in heating method and thermal field design, the average power consumption of the crystal growth can be greatly reduced.
In addition to the development of large-size single crystal growth technology, Sino-US Blue Crystal has also developed large-scale chip precision processing technology and high-efficiency micro-nano patterning technology. It is one of the few in the world with KY crystal growth, straight pull crystal growth, high The company of quality WPSS and DPSS process technology, and has a number of domestic and foreign invention patents, can improve customer extension quality and LED brightness.
Zhongmei Jing said that although the market for domestic sapphire substrates is still mainly 2" and 4", Sino-US Blue Crystal is the first to develop 6" WPSS and 6" DPSS to meet the requirements of next generation specifications.
Zhongmei Jing said that after the merger of Sino-US Blue Crystal and Zhaoyuan, not only through technology integration and capacity expansion, but also to enhance equipment operation efficiency and economies of scale, it will also combine production and R&D technical capabilities with R&D leadership. Open the distance with other competitors and pursue high-tech technology trends with customers. 
Sino-US Blue Crystal develops large-scale C-axis sapphire single crystal pulling and PSS technology
On September 27th, Sino-US Crystal and its subsidiaries, Sino-US Blue Crystal and Zhaoyuan jointly held the conference on the "Key Technology and Material Development of High-efficiency White LED Lighting". Sino-US Blue Crystal released large-size C-axis sapphire single crystal. The lifting technology, as well as the large size and high uniformity of patterned sapphire substrate (PSS) technology.
