$236 Hiroshima Semicon Gas Facility
Air Liquide Invests €200 Million in Japan to Support Next-Generation Semiconductor Production
Air Liquide has announced a €200 million ($236 million) investment in Hiroshima, Japan, to support the expansion of advanced semiconductor manufacturing, particularly for next-generation AI chips. The project will see the company design, build, own, and operate two state-of-the-art industrial gas production units under a long-term supply agreement, with operations expected to commence by the end of 2028.
The investment reflects accelerating global demand for high-performance semiconductors driven by artificial intelligence, data centres, and compute-intensive applications. It also reinforces Japan’s strategic role in the global semiconductor supply chain, as governments and industry continue efforts to strengthen domestic chip production capabilities.
Air Liquide’s development aligns with a broader industry trend of co-locating critical infrastructure directly at semiconductor fabrication sites. Ultra-high-purity gases such as nitrogen, oxygen, and argon are essential to chip manufacturing processes, where even the smallest impurities can impact performance and yield. By situating production on-site, the company aims to ensure reliability, efficiency, and quality for its semiconductor customers.
The Hiroshima project will supply large volumes of these gases directly to the fabrication facility, supporting advanced manufacturing requirements for AI-driven technologies.
As global investment in digital infrastructure accelerates, including large-scale AI data centres across Asia, initiatives such as this highlight the growing importance of integrated supply chains in enabling next-generation semiconductor innovation.
