TEMC

What TEMC does

TEMC Co., Ltd. (KOSDAQ: 425040) is a South Korean specialty-gas manufacturer founded in January 2015 and headquartered in Boeun-gun, Chungbuk. The company produces high-purity rare gases (neon up to 6N/99.9999%, xenon 5N5, krypton 5N5), pure specialty gases (C4F6, CO, CHF3, COS, 11BF3, C4F8, C3F8, CH2F2), and custom gas mixtures—including excimer laser mixes (ArF/KrF variants) for photolithography and ELA-LTPS, 11BF3/H2 mixes for ion implantation, and F2, SiH4/Si2H6, BCl3, and B2H6 mixes. Its technology stack is built around proprietary Ne/He separation and cryo-purification (84,000 NM3/year neon capacity), Xe/Kr cryogenic distillation (26,400 NM3/year), CO adsorption and HP purification (67,000 NM3/year at 4N5), excimer laser gas mixing (12,000 cylinders/year), and 11BF3 mixture production (6,000 cylinders/year) under full PLC control. The company also owns granted Korean patents on Kr/Xe/Ne separation methods from mixed gases and multi-stage container loading, and has been issued ISO 9001, 14001, 45001, and 37301 certifications.

TEMC makes money by selling these gases under direct B2B enterprise contracts to semiconductor and display manufacturers, primarily SK Hynix, Samsung Electronics, DB HiTek, and Magnachip, with multi-year supply agreements and quote-based pricing tied to purity specifications and volume. It holds the Cymer (ASML) Global Certificate for Kr/Ne excimer laser gases—one of only three companies globally with that qualification—alongside Gigaphoton (Ar/Xe/Ne, Kr/Ne) and AP System (HCl/H2/Ne) certifications, which act as the primary gatekeepers for lithography and ELA tool integration. Following its January 2023 KOSDAQ IPO and the October 2023 acquisition of a 33.4% stake in Oceanbridge for ~654 billion KRW, TEMC has expanded into precursors (HCDS, TiCl4, BDEAS), disilane (Si2H6), and semiconductor/secondary-battery process equipment, while operating a group structure that includes TEMC CNS, T-ENG, YHT, and TEMC AM.
