Air Liquide invests over $170M in Indiana to supply ultra-pure gases to SK hynix fab

Air Liquide will build, own and operate two new production units in Indiana under a long-term contract to supply ultra-pure gases to SK hynix's first U.S. fab. The investment exceeds 170 million US dollars, and the units will be commissioned at the end of 2028. Supplied gases include nitrogen, oxygen, argon and hydrogen, delivered to SK hynix's advanced chip packaging facility for High Bandwidth Memory production.

Key facts

Market context

Industrial gases such as nitrogen, oxygen, argon and hydrogen are essential utilities in semiconductor manufacturing, where they serve as inert purge and blanketing media, process gases, and carriers in cleaning, etching and packaging steps. Ultra-pure grades are needed because even trace contamination can reduce chip yields. Demand is driven mainly by the semiconductor and electronics sector, and within it by advanced packaging and high-bandwidth memory, which are tied to AI infrastructure build-outs. Supply for fabs is typically secured through long-term contracts, often with onsite or nearby production units owned and run by the gas supplier, so that volumes and purity are guaranteed. Such arrangements give suppliers predictable, high-volume revenue and tend to limit the share of spot business open to competitors. For buyers and investors, they signal that gas supply is being built into fab plans well before production starts, and that the major industrial gas companies remain the main providers of this infrastructure.
