Chemtronics readies to produce key solvent for photoresists
Photoresists have been slow to manufacture in Korea due to the difficulty in producing high-purity solvents
Chemtronics Co. Ltd., a South Korean chemical materials maker, appears to have removed a key hurdle to expanding the domestic production of photoresists.
Photoresists are among the three core materials for semiconductors and displays, for which Japan has imposed controls on exports to South Korea since 2019.
Kosdaq-listed Chemtronics recently succeeded in test-producing propylene glycol methyl ether acetic acid (PGMEA) with high purity. It accounts for a large portion of the manufacturing process of photoresists.
