High-purity electronic grade sulfuric acid has broad prospects and a market capacity of 100,000 tons

High-purity electronic-grade sulfuric acid is an ultra-clean and high-purity reagent. It is an indispensable key basic chemical reagent in the development of microelectronics technology. It is widely used in the assembly and processing of semiconductors and very large-scale integrated circuits. It is mainly used in the processing of silicon wafers. Cleaning and etching can effectively remove impurity particles, inorganic residues and carbon deposits on the wafer. The purity and cleanliness of high-purity electronic-grade sulfuric acid have an important impact on the yield, electrical performance and reliability of electronic components.

At present, the core technology of high-purity electronic grade sulfuric acid is monopolized by countries such as Germany, Japan, and the United States, and there are very few domestic and foreign literature reports on its key technologies. There are only a few companies in the world that can produce high-purity sulfuric acid on a large scale, such as BASF, Mitsubishi Chemical, Kanto Chemical, Chemtrade, Avanto Corporation, Lianshi Electronics, etc.

China’s high-purity electronic-grade sulfuric acid industry started late. For a long time, market demand has mainly relied on imported products, especially mid- to high-grade products, which are extremely dependent on imported products. In recent years, China’s semiconductor industry has developed rapidly, and the demand for high-purity electronic-grade sulfuric acid has also continued to grow. In order to prevent the development of domestic industry from being choked by foreign companies, investment in research related to high-purity sulfuric acid has continued to increase, and more technical achievements have been achieved. . At present, the number of domestic enterprises with large-scale production of high-purity electronic-grade sulfuric acid is constantly increasing.

In recent years, with the rise of China’s semiconductor industry, the localization rate has continued to increase, and there is an urgent need to improve the layout of the upstream and downstream industrial chain. The demand for high-purity electronic-grade sulfuric acid has shown rapid growth. According to the “2022-2026High Purity Electronic Grade Sulfuric AcidIndustry In-depth Market Research and Investment Strategy Suggestion Report” China’s consumption of high-purity electronic-grade sulfuric acid will reach 100,000 tons in 2021.

Industry analysts said that with the improvement of production technology in the future, high-purity electronic-grade sulfuric acid will be used in semiconductors, LCD panels and other fields. The demand will continue to grow, and new application areas will continue to be developed, which will promote the continuous release of product market demand and promote the rapid development of the overall industry, with broad prospects for industrial development.
