The dichlorosilane industry has good development prospects. Domestic substitution in my country’s electronic grade dichlorosilane market is imperative.

Dichlorosilane, also known as dichlorosilane, refers to a chemical substance with the chemical formula SiH2Cl2. It appears as a colorless gas under normal temperature and pressure. It is toxic and has a special smell. It is soluble in benzene, ether, and tetrachloride. Most organic solvents such as carbon. According to different uses, dichlorosilane can be divided into two categories: electronic grade dichlorosilane and industrial grade dichlorosilane.

At present, the production methods of dichlorosilane are mainly divided into three categories: disproportionation method, which refers to the method of using trichlorosilane as raw material and producing dichlorosilane through catalytic disproportionation reaction, separation, purification and other links; chlorination method The cyanide method refers to the method of using silicon powder and hydrogen chloride as raw materials, through chemical reaction, distillation and purification to obtain dichlorosilane; the cyanide method refers to using silicon tetrachloride and trichlorosilane as raw materials, through chemical reaction Method to generate dichlorosilane. Among them, high-purity dichlorosilane products can be prepared through the chlorination method, which is the current mainstream production method.

Dichlorosilane is a type of high value-added chemical product, mainly used in the fields of electronics and chemical industry. In the electronic field, dichlorosilane is mainly used as a silicon source in the vapor phase epitaxial process used in silicon epitaxial growth. At the same time, it can also react with nitrogen oxides to generate silicon dioxide and is used in the insulating layer and passivation of integrated circuits. Layer manufacturing scenarios; in the chemical industry, dichlorosilane can be used as a silylating agent in pharmaceutical and chemical product production scenarios.

Among them, electronics is the main application field of dichlorosilane, and electronic grade dichlorosilane is mainly used in the production scenario of 12-inch silicon epitaxial wafers. Under the current background of rapid development and upgrading of the domestic semiconductor industry, the market penetration rate of 12-inch silicon epitaxial wafers is continuously increasing, which in turn drives the market demand for electronic-grade silicon dichloride to continue to increase, and the industry shows good development prospects.

According to the “China Dichlorosilane Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research CenterIt shows that the number of companies in the dichlorosilane market in my country is relatively small, with only a few such as Tangshan Sanfu Electronic Materials and Luoyang China Silicon High-tech. Moreover, the domestic demand for electronic grade dichlorosilane still mainly depends on imports. . At present, the global electronic grade dichlorosilane production capacity is still mainly concentrated in Japan. The main companies are Japan’s Shin-Etsu Chemical and Taiyo Nippon Sanso. In recent years, Japan’s Shin-Etsu Chemical has occupied more than 80% of the global electronic grade dichlorosilane market.

Industry analysts said that dichlorosilane is a new type of silicon-based material, which is mainly used in the field of semiconductor manufacturing. Under the current background of the continuous development and upgrading of my country’s semiconductor industry, electronic grade dichlorosilane, as the key silicon source for 12-inch silicon epitaxial wafers, has continued to increase its market demand and become increasingly important. However, the current domestic demand for electronic-grade dichlorosilane still relies on imports. In the future, local companies will need to increase technology and product research and development efforts. Domestic substitution in the domestic electronic-grade dichlorosilane market is imperative.
