What is the purpose and key feature of Air Liquide's new $160 million plant in Arizona?

Air Liquide is investing over $160 million to build a large-scale facility in Arizona that will produce low-carbon, ultra-pure hydrogen—enabled by carbon capture—as well as other high-purity gases essential for semiconductor manufacturing. The plant will supply these gases to a global leader in advanced semiconductor nodes, capture CO₂ onsite, and begin operations in 2028. It supports reshoring of chip manufacturing in the US and builds on Air Liquide’s existing presence at the site.

Why is hydrogen critical for semiconductor manufacturing, according to the news?

According to the news, hydrogen is essential for semiconductor manufacturing because it is primarily used in wafer manufacturing, annealing, and removing surface oxides during the most sensitive chip manufacturing processes.
