Recently, the company's technology research and development department and manufacturing department under the leadership of Chairman Dr. Pan Liansheng, work together to overcome the difficulties, under the existing equipment conditions, the successful use of 28 inches of thermal field to grow a diameter of 550mm (22 inches) of high-quality silicon monocrystals. The smooth release of the crystal is the result of the company's long-term hard work in the field of semiconductor silicon materials, the embodiment of the company's advanced process technology, and the company's strategic goal of becoming a leader in the field of semiconductor silicon materials in China and even the world.

The silicon crystals developed this time will be mainly used in the field of etching machines. With the development of science and technology, the size of integrated circuit silicon chips is gradually increasing, and the manufacturing process is more and more advanced, which also puts higher requirements on etching equipment. As an important production material in the etching machine, the 22-inch super-sized silicon monocrystals obviously have a broader space to play, and are very competitive in the market.
Through accurate research and judgment of the development trend of the industry, the company actively cooperated with customers to research and develop monocrystalline silicon materials for ultra-large silicon electrodes. After painstaking efforts, the technicians have carried out technical innovations on the equipment, thermal field, control conditions, etc., effectively solving the technical problems encountered in the growth of ultra-large diameter single crystals. And after repeated research, the growth process of single crystal is more stable. The smooth release of the new crystal has laid a solid foundation for the large-scale production of the company's ultra-large diameter products in the future.

In the future, the company will continue to implement the business philosophy of "focusing on technology, emphasizing quality and serving customers", and is committed to becoming an excellent silicon material supplier with excellent technical advantages and R&D strength, cost-effective products, leading market position, excellent quality management and good after-sales service in the field of semiconductor grade monocrystalline silicon materials in the world.
