Mitsui Chemicals announced that new affiliate Mitsui Chemicals EMS Corporation has begun doing business after its establishment on July 1, 2023

Created to take over the pellicle business acquired from Asahi Kasei Corporation, Mitsui Chemicals EMS is the No. 1 player in the market for FPD pellicles, which are used in the LCD panel exposure process. Mitsui Chemicals EMS has also gained a good reputation in the marketplace with DUV pellicles for semiconductor exposure processes. These DUV pellicles primarily find application in ArF immersion lithography, which is used in many cutting-edge domains.

At the same time, Mitsui Chemicals has been able to secure its own significant presence in the pellicle market. The company has become a leader in cutting-edge DUV pellicles, and also stands at the forefront in achieving commercialization of EUV pellicles – these being used in EUV lithography, an advanced technology in the semiconductor industry.

With the establishment of Mitsui Chemicals EMS, Mitsui Chemicals aims to further expand the pellicle business of the Group as a whole, developing new products and enhancing cutting-edge technologies as it seeks to become the world’s No. 1 diversified pellicle manufacturer.
