The mono-crystalline ingot production flow consists of crystal pulling, machining and polishing procedures. The lifetime of the minority carrier has been increased with oxygen concentration reduced and production capacity and silicon ingot yield rate continuously developed on the basis of our constant improvement of crystal pulling technology.
The mono-crystalline wafer production flow consists of cutting, cleaning and sorting procedures. The production capacity and wafer yield rate have been continuously improved to meet the clients’ requirements on wafer quality and yield with great endeavors to constant improve our cutting technology and final inspection capacity.
With Xi’an as the center, the company’s production bases are located in Yinchuan, Zhongning, Wuxi, and Chuxiong, Baoshan and Lijiang of Yunnan Province. It looks overseas and establishes the new overseas production base in Malaysia.
