The market size of electronic grade trichlorosilane continues to expand, and the production capacity of local companies needs to be improved.

Trichlorosilane, also known as trichlorosilane, has a molecular formula of Cl3HSi. It is an inorganic compound that appears as a colorless liquid. According to different uses, it can be divided into industrial grade trichlorosilane, electronic grade trichlorosilane and photovoltaic grade trichlorosilane. Hydrogen chloride, etc. Electronic grade trichlorosilicon refers to trichlorosilicon used in electronic and electrical fields such as silicon epitaxial wafers and semiconductor silicon carbide. In recent years, driven by market demand, the prosperity of my country’s electronic grade trichlorosilane industry has continued to increase.

The purity of electronic grade trichlorosilane is usually 8N, and purification is a key step in its production. Complexation-distillation, distillation and adsorption-distillation are the main purification methods. Affected by high technical barriers and other factors, my country’s electronic grade trichlorosilane is highly dependent on imports. In recent years, Chinese enterprises and scientific research institutions have continued to increase research on purification methods of electronic grade trichlorosilane. It is expected that the localization process of my country’s electronic grade trichlorosilane market will accelerate in the future.

Electronic grade trichlorosilicon is mainly used in the electronic and electrical fields, with silicon epitaxial wafers and semiconductor silicon carbide as its end products. Benefiting from national policy support, my country’s silicon epitaxial wafer market space continues to expand. my country’s silicon epitaxial wafer market size will reach 9.58 billion yuan in 2022, a year-on-year increase of 7.5%. As the development of downstream industries accelerates, the market demand for electronic grade trichlorosilane in my country is increasingly strong. According to the “2023-2028 China Electronic Grade Trichlorosilane Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center ” shows that the market size of my country’s electronic grade trichlorosilane will reach nearly 2.5 billion yuan in 2022.

At present, due to factors such as high technical barriers and high production costs, my country’s electronic-grade trichlorosilane production capacity is low, and countries such as Germany, Japan and the United States dominate the global market. Wacher of Germany, TOKUYAMA of Japan, and Dow Corning of the United States are world-renowned electronic-grade trichlorosilane manufacturers, and all of the above companies have large-scale production capabilities.

my country’s electronic grade trichlorosilane industry has a high degree of concentration. The main production companies include Sanfu Co., Ltd., Levima Xinco, Heyuan Gas, Jingxing Technology, Luoyang China Silicon, Qinyang Lingkong, etc. Sanfu Co., Ltd. is a representative enterprise of electronic grade trichlorosilane in my country. It focuses on the R&D, production and sales of trichlorosilane, electronic grade trichlorosilane, silicon tetrachloride, silane coupling agents and other products. It has 1,000 tons of /year electronic grade trichlorosilicon production capacity, the company’s products are currently used to produce 6-8 inch silicon epitaxial wafers.

Industry analysts said that with the accelerated development of the semiconductor industry, the market size of my country’s electronic grade trichlorosilane continues to expand. In recent years, with the in-depth research and technological progress of local enterprises, my country’s electronic-grade trichlorosilane production capacity has expanded, but it is still unable to meet downstream production needs, and the product is highly dependent on imports. Overall, my country’s electronic-grade trichlorosilane industry still has huge room for development.
