PARIS and SEOUL, South Korea, June 3, 2026 /PRNewswire/ --  Air Liquide has signed a major long-term contract with SK hynix, a global leader in memory semiconductors. The Group will bring its pioneering solutions to SK hynix's massive industrial project dedicated to advanced packaging of HBM (High-Bandwidth Memory), the backbone of the global AI revolution. The investment of nearly 200 million euros is a first success following the acquisition of DIG Airgas earlier this year, significantly strengthening its leadership in both the region and the Electronics industry.

In order to supply SK hynix's new packaging and testing fab "P&T7", located in Cheongju, in the Chungcheongbuk province, Air Liquide will build and operate a state-of-the-art nitrogen production unit. Set to begin operations in late 2027, the facility will supply high-purity gases and high-purity compressed air to the fab in charge of the advanced packaging of HBM chips, a key component of AI development.

This contract demonstrates the immediate value creation by integrating South Korea's leading industrial gas provider DIG Airgas into Air Liquide. By combining the Group's world-class proprietary technologies for ultra-high purity carrier gases with DIG Airgas's extensive local footprint and deep-rooted customer relationships, Air Liquide has significantly accelerated its growth trajectory and potential in the region. This strategic synergy uniquely positions the Group to lead the rapid evolution of AI-driven semiconductor manufacturing. With this new project, the Group will also significantly expand its footprint in the Cheongju industrial basin, where its teams already operate several plants supporting SK hynix, reinforcing its long-term competitive edge in the South Korean market.

Ronnie Chalmers, Air Liquide Group Vice President, in charge of supervising Asia-Pacific, stated: "This milestone partnership reflects our strong confidence in the South Korean economy and our long-standing commitment to being a preferred partner in the global semiconductor supply chain. Thanks to the integration of DIG Airgas, which brought us a secured portfolio of nearly 20 projects, our teams now combine local agility and global innovation to accelerate Air Liquide's growth. We are proud to support the ambitions of our partner SK hynix as they play a leading role in the AI revolution."
