China is still catching up in the semiconductor industry, but the overall gap is still very large. For example, silicon wafers used to manufacture chips are in the hands of a handful of companies in Japan, Germany, and South Korea.
However, we also broke through one by one! According to reports, Jiangsu Xinhua Semiconductor Materials Technology Co., Ltd. has successfully mass-produced electronic grade polysilicon with a purity requirement of 99.999999999%. After undergoing a series of rigorous tests, the company has not only supplied to the domestic market but also exported to South Korea..
This indicates that China's silicon materials for semiconductor integrated circuits have reached world-class quality standards, which is also the first time that China's polysilicon manufacturing companies export high-purity silicon materials for integrated circuits to the international market. In the past, China basically relied on imports.
The electronic grade polysilicon material is the key basic material of the integrated circuit, and also the polysilicon material with the highest purity. The purity requirement of the solar grade polysilicon is only 99.9999%, and the electronic grade is more than five 9.
More vividly, The impurity content of 5000 tons of electronic grade polysilicon is only about 6 grams, equivalent to the weight of a 1 dollar coin.
In December 2015, Xinhua Semiconductor jointly invested 3.8 billion yuan from the National Integrated Circuit Industry Investment Fund and GCL-Poly to build the first 5,000-ton semiconductor integrated circuit-dedicated electronic-grade polysilicon production line. On November 8, 2017, it officially released an electronic grade. Polysilicon products.
At present, the electronic grade polysilicon has passed customer verification and formed a large-scale sales, breaking the monopoly of foreign high-purity materials for a long time, and filling the industry's domestic technology gap.
Xinhua Semiconductor's electronic-grade polysilicon production capacity can guarantee that domestic companies will not be out of stock within 3-5 years. The product quality meets the requirements for 40-mm process and the following 300-mm size single crystal manufacturing for very large-scale integrated circuits. At the same time, another 5000-ton production line will be planned. , to better meet the international and domestic markets.
