Industrial Gas Supply Strengthens SK hynix AI Memory Packaging in Cheongju and Indiana

When chip makers cram billions of transistors into smaller and smaller spaces, even slight changes in gas purity can mess with yields and profits. Earlier this year, Air Liquide, a leader in industrial gases and technologies from France, made some significant moves by investing in its gas supply operations. This will help SK hynix with its cutting-edge memory packaging in both South Korea and the United States.

Two Geographies, One Strategy

In Cheongju, located in North Chungcheong Province, Air Liquide is all set to build a state-of-the-art high-purity nitrogen unit at SK hynix's new packaging and testing fab, known as P&T7. This project comes with a hefty investment of nearly €200 million, and they're aiming to have it up and running by late 2027. The new nitrogen plant will directly provide inert gas, compressed air, and other ultra-pure gases into the clean-room process lines, which will help avoid delivery delays and contamination risks.
