Samyang Corp. unveiled an ultrapure water ion exchange resin for next-generation semiconductor manufacturing at its TRILITE DAY 2026 event on Oct. 28. About 70 employees and executives from water treatment customers attended the event, held in the auditorium on the first floor of the company’s headquarters in Jongno, Seoul.

The newly introduced MaxPurity UPRM500U is an ion exchange resin used in the final purification stage of ultrapure water production. The company significantly reduced impurities within the resin itself, cutting sodium content by 94% compared with the previous UPRM400U product. It also lowered the concentrations of eight metals, including iron, calcium and magnesium. Ion exchange resins are synthetic resin beads that act as filters to adsorb or remove substances.

Ultrapure water is water from which ions, organic substances and fine particles have been removed to extremely low levels, leaving essentially only water molecules. The purity of the ion exchange resin itself determines the purity of the ultrapure water that comes into contact with semiconductor wafers. Because the water directly contacts wafer surfaces, even trace amounts of impurities can affect yields in fine-circuit manufacturing processes.

Samyang also unveiled New TriAngle, its proprietary artificial intelligence (AI)-based integrated water treatment design software. By entering parameters such as treatment flow rate, raw water conditions and operating time, users can receive an AI-generated recommendation for an optimal water treatment process meeting target water quality requirements within one minute. The software recommends not only ion exchange resins but also reverse osmosis (RO), which removes impurities from water, and electrodeionization (EDI), which removes trace ions. Samyang said it is the first company to develop such an integrated analysis solution.

Samyang is the only domestic producer of ion exchange resins in South Korea and operates the dedicated TRILITE brand. The event was organized to introduce products designed to meet increasingly stringent ultrapure water standards in semiconductor manufacturing amid advances in AI and growing demand for high-bandwidth memory (HBM).

“We have reached the point where the purity of every individual ion exchange resin bead used in semiconductor ultrapure water production must be controlled, and we will accelerate commercialization to contribute to domestic production,” said Cho Young-do, head of Samyang’s WS Performance Unit (PU). “The New TriAngle solution introduced today will also shorten the design period for water treatment systems.”
