en.Wedoany.com Reported - July 16, 2026 – Air Liquide S.A. (Paris, France) announced a new investment of over $160 million to build, own, and operate a large-scale production facility in Arizona, USA, to supply critical ultra-high purity gases to a global leading advanced semiconductor node manufacturer for its latest wafer fab expansion project. The facility is scheduled to begin operations in 2028 and will supply a range of gases, including ultra-pure low-carbon hydrogen produced using carbon capture technology.
Hydrogen is a key gas in semiconductor manufacturing, primarily used for wafer fabrication, annealing, and removing surface oxides in the most sensitive chip-making processes. To achieve the extreme precision and reliability required for manufacturing chips that drive future artificial intelligence infrastructure and high-performance computing, Air Liquide will operate hydrogen production and carbon capture units directly on the customer's fab site. The captured carbon dioxide will be liquefied and purified on-site to meet the customer's demand for high-purity gases, thereby reducing the carbon footprint of the hydrogen used in chip manufacturing.
This investment builds on Air Liquide's existing operations in the region and underscores the customer's continued trust in the Group's ability to reliably support its major capacity expansions. The Group will also leverage existing local infrastructure to maximize operational efficiency. Air Liquide continues to play a key role in localizing the semiconductor supply chain by positioning its operations at the doorstep of major customers, providing critical components required for cutting-edge technologies in a safe and reliable manner.
Matthieu Giard, Member of the Air Liquide Executive Committee and Head of the Americas region, stated that this new investment highlights the confidence of advanced chip manufacturers in the Group's ability to ensure a reliable and economical supply of critical ultra-high purity gases with uncompromising quality and sustainability, which are essential to driving the domestic AI revolution. As semiconductor manufacturers increasingly relocate their operations back to the United States, the Group successfully supports their growth ambitions with its leading, unique, and comprehensive expertise in the electronics sector.
