Air Liquide is investing more than $160 million in the United States to build and operate a large-scale production facility in Arizona aimed at supporting the next phase of advanced semiconductor manufacturing.
The new facility will supply critical ultra-high purity gases to a global leader’s expanding advanced chip manufacturing operations, strengthening Air Liquide’s role as a key supplier for the rapidly growing U.S. semiconductor and artificial intelligence supply chain.
Scheduled to begin operations in 2028, the state-of-the-art site will produce essential gases including ultra-pure, low-carbon hydrogen, supported by carbon capture technology. Hydrogen plays a crucial role in semiconductor production, including wafer manufacturing, annealing, and removing surface oxides during some of the industry’s most demanding chip fabrication processes.
Air Liquide will operate hydrogen production and carbon capture units directly at the customer’s semiconductor facility, allowing the company to deliver the precision, reliability, and efficiency required for next-generation chips powering AI infrastructure and high-performance computing.
The company will also use its existing local infrastructure to improve operational efficiency, while captured carbon dioxide will be liquefied and purified for use in the customer’s high-purity gas applications. The project is expected to help reduce the carbon footprint associated with hydrogen used in chip manufacturing.
The investment comes as semiconductor companies accelerate efforts to expand domestic production in the United States. By placing operations close to major chip manufacturers, Air Liquide aims to provide a secure and reliable supply of the materials needed for cutting-edge technologies.
Matthieu Giard, Group Executive Committee member, notably supervising operations in the Americas, stated: "This new investment underscores advanced chip manufacturers’ confidence in Air Liquide’s capacity to ensure reliable, cost-effective supply of critical ultra-pure gases required to power the AI revolution domestically, sustainably and with uncompromising quality.
"As semiconductor manufacturers are increasingly reshoring their activities in the US, we successfully support their growth ambitions thanks to our leading, unique and comprehensive expertise in the Electronics sector.”
The Arizona project reinforces Air Liquide’s position as a strategic partner in the global semiconductor industry as demand surges for AI chips, advanced computing systems, and resilient domestic supply chains.
