Air Liquide Fuels the AI Revolution: New Strategic Partnership with SK hynix for HBM Technology

The global race for Artificial Intelligence (AI) supremacy isn’t just about software and algorithms; it’s about the physical infrastructure and materials that make high-speed computing possible. In a move that underscores this reality, Air Liquide, a global leader in gases, technologies, and services for Industry and Health, has announced a landmark long-term contract with SK hynix.

A Strategic Investment in the Future of AI

Air Liquide is committing nearly EUR 200 million to support SK hynix’s ambitious industrial project focused on the advanced packaging of High Bandwidth Memory (HBM). This investment is a pivotal step in enhancing the production capabilities of one of the world’s most critical components for AI development.

The project will center around the new packaging and testing facility, known as “P&T7,” located in Cheongju, South Korea. To meet the rigorous demands of this fab, Air Liquide will design, build, and operate a state-of-the-art nitrogen production unit.

Why HBM Chips Matter for AI

For those unfamiliar, High Bandwidth Memory (HBM) is a specialized RAM interface that allows for significantly faster data transfer speeds compared to traditional memory. This is essential for AI accelerators and GPUs that process massive datasets in real-time.

By the time operations begin in late 2027, Air Liquide’s facility will provide:

n
• Ultra-high purity nitrogen: Essential for maintaining a contaminant-free environment during chip fabrication.
• High-purity compressed air: Necessary for the precision machinery used in advanced packaging.
• Proprietary carrier gas technologies: Ensuring the highest standards of purity and stability.

Expanding the Footprint: The Role of DIG Airgas

This expansion is not a coincidence. The partnership follows Air Liquide’s strategic acquisition of DIG Airgas earlier this year. By integrating DIG Airgas’s established local presence and customer relationships in the Asia-Pacific region with Air Liquide’s global innovation, the company is accelerating its growth in the semiconductor sector.

“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,” stated Ronnie Chalmers, Air Liquide Group Vice President for Asia-Pacific.

Looking Ahead

As SK hynix continues to play a leading role in the AI revolution, the collaboration with Air Liquide ensures that the hardware foundation is robust, scalable, and efficient. This partnership highlights the symbiotic relationship between industrial gas providers and the semiconductor industry, proving that the path to smarter AI is paved with high-purity chemistry and engineering excellence.

With the P&T7 fab set to go live in 2027, the industry can expect a significant boost in the availability of high-performance memory, further propelling the capabilities of generative AI and large language models worldwide.
