SAMYANG NC Chem Corp. is a South Korea-based specialty electronic materials company that develops, manufactures, and commercializes high-purity chemical raw materials for semiconductor photolithography processes. Operating as a key electronic materials subsidiary of Samyang Holdings Corporation, the company specializes in custom organic synthesis and ultra-high-purity purification technologies to supply essential precursors and functional compounds for advanced photoresist formulations. The company's primary product portfolio encompasses Photoacid Generators (PAGs), including sulfonium-based and iodonium-based onium salts engineered for KrF (248 nm), ArF immersion (193 nm), and Extreme Ultraviolet (EUV) photolithography; Photoactive Compounds (PACs), comprising diazonaphthoquinone (DNQ) sulfonic acid esters utilized in I-line and G-line photoresists; specialty monomers and polymer resins designed for chemical amplification and fine patterning; basic quenchers and acid scavengers to regulate acid diffusion and optimize critical dimension uniformity; and specialized electronic chemical additives, crosslinkers, and high-purity process solvents for semiconductor and display fabrication. SAMYANG NC Chem Corp. serves multinational photoresist formulators, semiconductor foundries, and integrated device manufacturers across South Korea, Japan, Taiwan, the United States, and broader international markets. Founded in 2008 as NC Chem and headquartered in Gongju-si, Chungcheongnam-do, South Korea, the company maintains synthesis plants and dedicated analytical research and development centers in South Korea. In recent developments, SAMYANG NC Chem Corp. completed its public listing on the KOSDAQ exchange (KRX: 482630) to fund manufacturing infrastructure and advanced chemical synthesis lines; expanded production capacity at its Gongju manufacturing complex to meet surging demand for next-generation EUV and high-NA EUV photoresist materials; advanced commercialization of low-defect raw materials engineered to sub-parts-per-billion purity standards for sub-3nm node semiconductor manufacturing; and strengthened commercial and operational synergies across Samyang Group's chemical business portfolio to broaden direct supply agreements with leading global semiconductor chemical manufacturers.
