Toyo Engineering Korea Ltd., a subsidiary of Toyo Engineering Corp. (Chiba, Japan), has been awarded a contract by HANTOK CHEMICALS CO., LTD. (HANTOK) for the construction of a Tetramethylammonium Hydroxide (TMAH) production plant in South Korea.
HANTOK is a 50:50 joint venture between Tokuyama Corp. (Tokyo, Japan) and LOTTE Chemical Corp. (Seoul, South Korea). Toyo-Korea will be responsible for selected procurement activities, construction, and commissioning support. The project is scheduled for completion in FY2027.
TMAH is used as a photoresist developer in semiconductor manufacturing processes. Demand is expected to continue growing, driven by growing demand for advanced semiconductors. HANTOK plans to double its existing TMAH production capacity. The new plant forms part of a strategic investment program aimed at establishing a reliable supply system for TMAH.
Drawing on its extensive project execution experience and engineering expertise in South Korea, Toyo-Korea (Chiba, Japan) will continue to support the growth of the semiconductor industry.
