Air Liquide to supply SK hynix with €200m plant in South Korea - gasworld

French industrial gas leader Air Liquide has announced an investment of nearly €200 million (approximately $232 million) in South Korea to build a nitrogen production facility that will supply high-pu... Read original →

Air Liquide’s €200M bet on SK hynix’s HBM advanced packaging line is a strategic move to lock down the ultra-pure gas backbone of AI chip manufacturing. With nitrogen purity demands now at ppt levels for wafer-level packaging, rivals like Linde and Taiyo Nippon Sanso must accelerate localized deployment—or risk losing cost and responsiveness advantages. South Korea’s push for materials self-reliance ironically reinforces foreign gas giants’ grip due to safety and scale barriers. Crucially, if SK hynix scales HBM output at its Wuxi, China fab amid tightening U.S.-EU export controls, its gas supply chain could face secondary sanctions scrutiny. Over the next 18 months, industrial gas leaders will race to co-locate plants beside TSMC, Samsung, and SK hynix fabs—transforming gas from a utility into a gating factor for AI chip capacity.
