Shin-Etsu Chemical to build fourth production base for semiconductor lithography materials

Shin-Etsu will build a new manufacturing and research-and-development base for semiconductor lithography materials

  • By ICN Bureau | April 10, 2024

Shin-Etsu Chemical Co.has announced that in order to expand its semiconductor lithography materials business, the company decided to build a new plant in Isesaki City in Gunma Prefecture, Japan. The new plant will become Shin-Etsu’s fourth production base for this business.

Shin-Etsu has acquired an about 150,000 ㎡ business site in the city where it will build a new manufacturing and research-and-development base for semiconductor lithography materials. After considering several potential sites for the new plant, we selected this site in close cooperation with both Gunma Prefecture and Isesaki City. We plan to invest in the new plant in phases, with the first phase of investment to be completed by 2026. The investment, including the acquisition of the land, is expected to amount to about ¥83 billion yen at the completion of the first phase of construction, and it will be funded entirely by using the company’s own funds. 

Shin-Etsu launched its photoresists business in 1997 and started production of the then-most cutting-edge KrF photoresists at our Naoetsu Plant in Niigata Prefecture, Japan. Since then, the company has successfully developed and commercialized a succession of semiconductor lithography materials such as photomask blanks, ArF photoresists, multilayer materials, extreme ultraviolet (EUV) resists and others. The company established the second production base in Fukui Prefecture in 2016 and the third production base in Yunlin County in the western part of Taiwan in 2019 for our semiconductor lithography materials business, and we have achieved a stable supply of these products.

Shin-Etsu Chemical will continue to focus on the development of the new base as well as its semiconductor lithography materials business in order to meet the expectations of our customers and society.
