Jingrui Shares partners with Mitsubishi Chemical to build China’s 90,000-ton-per-year electronic-grade sulfuric acid plant.

Jingrui Shares (stock code: 300655) has consistently focused on the R&D and manufacturing of electronic materials. Its product portfolio includes four major categories of microelectronic chemicals: ultra-pure, high-purity reagents, photoresists, functional materials, and lithium-battery binders. As integrated circuits are a strategic industry in China, it is crucial to build and improve the industrial chain, including key materials. Leveraging the advantage of its subsidiary, which boasts an annual production capacity of 300,000 tons of high-quality industrial sulfuric acid raw materials, Jingrui Chemical has combined this with advanced manufacturing technology for electronic-grade sulfuric acid—introduced from Mitsubishi Chemical Corporation of Japan—to invest in the construction of a project with an annual output capacity of 90,000 tons of electronic-grade sulfuric acid. The project is located in southern Jiangsu Province.

　　As a strategic industry in China, the integrated circuit sector urgently requires the development and improvement of its industrial chain, including key materials. RuiCheng Chemical, leveraging the advantage of its subsidiary’s annual production capacity of 300,000 tons of high-quality industrial sulfuric acid raw materials, and drawing on advanced manufacturing technology for electronic-grade sulfuric acid introduced from Mitsubishi Chemical Corporation of Japan, is investing in the construction of an electronic-grade sulfuric acid project with an annual output of 90,000 tons. The project is located in Nantong City, Jiangsu Province, and is expected to begin formal operation in July 2019. The product’s technology will cover process nodes down to 10-nanometer-level manufacturing processes used in integrated circuit fabrication. Mitsubishi Chemical’s high-purity sulfuric acid technology is a world-leading solution, with decades of extensive application experience among numerous advanced semiconductor chip manufacturers globally.

　　The construction of this project is of great significance to both the nation and the industry. Currently, China largely relies on imports for high-end sulfuric acid used in semiconductors. With the rapid expansion of China’s 8- to 12-inch wafer fabs, future market demand is expected to reach 200,000 to 300,000 tons. Consequently, high-grade sulfuric acid is likely to face shortages within the next few years. Through the implementation of this project, high-purity sulfuric acid products will become another offering—following Jingrui Chemical’s high-purity hydrogen peroxide—that attains world-class advanced standards. Upon completion, the project will enable us to provide customers with more timely and efficient services and a more secure supply chain, while also making a significant contribution to the localization of semiconductor materials in China.
