          China's first 8-inch silicon melting single crystal come out

          China Central Semiconductor Co., Ltd. recently announced three new products: China's first 8-inch fused silicon single crystal, Czochralski melting high-efficiency solar cell silicon single crystal and 8-inch <110> crystal Czochralski silicon single crystal. According to reports, these three new products have gradually moved from the laboratory to the application stage; the company also hopes to rely on Czochralski melting technology to enter the field of high-efficiency solar cell applications and achieve industrial production.

          Central shares are mainly engaged in semiconductor silicon single crystal materials, single crystal silicon photovoltaic products and semiconductor devices. At present, there are two kinds of technologies in silicon single crystal growth in China, namely Czochralski and zone melting methods. It is still difficult to achieve 6 inches or more due to different process zones. District melting products can be applied in the field of power electronics, optoelectronics, detectors, and solar cell applications. According to statistics, there are currently nearly 20 regional melt crystal monolith manufacturers globally, of which the top five companies have monopolized global production of more than 95%. Central shares account for 18% of the market. German company SILTRONIC has started to sell 8-inch area silicon wafers in small quantities. In 2009, Central shares have developed a 7-inch area silicon single crystal. The 8 inch silicon melt single crystal that was announced this time is the first in China.

          In the field of Czochralski silicon single crystals, in recent years, there has been an increasing interest in the research of <110> crystal CZCs at home and abroad. It is understood that China Central is currently also in cooperation with some domestic and foreign companies to conduct early research and development. At present, these two products have entered the customer sample delivery and evaluation stage. In addition, despite this year's global photovoltaic industry is facing excess capacity and the industry reshuffle, but Central shares still announced that they will rely on the latest technology, a new generation of Czochralski fusion method to enter the field of high-efficiency solar silicon single crystal.
