ZEON has started construction of a new single-wall carbon nanotube (SWCNT) plant at its Tokuyama Factory in Shunan, Yamaguchi. The plant will use an advanced proprietary process based on the Super Growth method and is expected to begin full-scale operations in 2028, expanding production capacity several dozen times from the current level to meet growing lithium-ion battery demand.
ADEKA will build a new manufacturing plant for its high-performance TRANSPAREX clarifying agent at the third plant of subsidiary ADEKA KOREA CORPORATION in Wanju County, South Korea. The plant will be built in surplus space at an existing semiconductor-materials facility to secure supply as demand expands; construction is scheduled to run from December 2026 to June 2028, with operations beginning in November 2028.
Fujifilm has completed a new building at the Oita plant of Fujifilm Electronics Materials Co., Ltd. and began operations in August 2026. The facility manufactures and tests post-CMP cleaners, adding automated production equipment and quality-evaluation instruments to expand the plant's manufacturing capacity to three times its previous level, supporting growing AI-semiconductor demand.
ADEKA will expand production equipment for photo-acid generators used in advanced semiconductor photoresists, including EUV lithography, by adding a manufacturing line inside an existing building at its Chiba plant in Sodegaura. The approximately ¥1 billion investment is scheduled to start construction in January 2027, finish in February 2028, and begin commercial operations in September 2028, doubling capacity from the current level.
Denco Techno Heat, a wholly owned subsidiary of DKK Co., Ltd., will relocate its Suzuka factory to a newly acquired site in Kono-cho, Suzuka, Mie. The new facility will use DX, robotics and automated induction-heating equipment to raise production capacity by 30% versus the existing plant, with a planned 244 kW self-consumption solar installation. The factory building is scheduled for completion in March 2027, with all equipment relocation due to finish in January 2028.
Tokuyama held the opening ceremony for a new semiconductor-grade polysilicon plant operated by its wholly owned subsidiary Tokuyama Vietnam in the Phu My 3 Special Industrial Park, Ho Chi Minh City. The facility will crush and wash polysilicon and serve as an overseas supply-chain hub, with trial operations and quality verification to follow.
