Read MoreHide Full Article

Key Takeaways

  • Air Liquide signed a long-term deal with SK hynix and will invest nearly EUR 200M in South Korea.
  • AIQUY will build a nitrogen unit for SK hynix's HBM packaging facility, due to start in late 2027.
  • Air Liquide's DIG Airgas acquisition helped secure a key semiconductor contract in South Korea.

Air Liquide S.A. (AIQUY - Free Report) recently announced a major strategic investment in South Korea to support the advanced AI memory chip expansion plans of SK hynix. The French industrial gases leader signed a long-term contract with SK hynix and will invest nearly €200 million (roughly $233 million) in infrastructure supporting the production of next-generation High-Bandwidth Memory (HBM) chips, a critical component used in Artificial Intelligence servers and accelerators.  

Air Liquide will build and operate a state-of-the-art nitrogen production unit to supply SK hynix’s new P&T7 packaging and testing facility in Cheongju, South Korea. The facility is dedicated to advanced packaging of HBM chips and is expected to begin operations in late 2027.  

Air Liquide will provide high-purity nitrogen, compressed air and other specialty gases required for semiconductor manufacturing, where even microscopic contamination can affect chip performance.  

The project is particularly significant because HBM chips have become the backbone of AI infrastructure. Demand for these memory products has surged as companies expand production of AI accelerators used in data centers worldwide. SK hynix is currently one of the world's leading HBM suppliers and has been aggressively expanding capacity to meet AI-driven demand. 

The investment also highlights the strategic importance of Air Liquide's recent acquisition of South Korean industrial gas company DIG Airgas. The SK hynix contract was one of the first major successes resulting from the acquisition. By combining Air Liquide's expertise in ultra-high-purity gases with DIG Airgas' local infrastructure and customer relationships, the company has strengthened its position in South Korea's semiconductor ecosystem.  

Shares of AIQUY are down 1.7% over the past year against the industry’s 3% growth.
