Air Liquide to Build Two Production Units for SK hynix's Advanced Chip Packaging Facility in Indiana - News and Statistics

Jul 2, 2026

Air Liquide S.A., based in Paris, is undertaking a long-term contract to build, own, and operate two new production units in Indiana. These units will supply ultra-pure gases to the first U.S. semiconductor fabrication facility of SK hynix, a South Korean leader in advanced memory chips. The investment exceeds $170 million and is intended to support rising demand for next-generation chips, which are essential for enabling the AI revolution.

Next-generation memory chips, such as High Bandwidth Memory (HBM), require increasing volumes of high-purity gases. Air Liquide will deliver large amounts of nitrogen, oxygen, argon, hydrogen, and other industrial gases to SK hynix’s new advanced chip packaging facility. The new units are scheduled to be commissioned at the end of 2028.

By installing the two state-of-the-art production units at the customer’s site, Air Liquide will ensure a continuous, high-quality supply directly to the manufacturing lines. This strategic proximity is critical for meeting the stringent, high-precision environment needed for advanced packaging, a key enabler for HBM. The process involves vertically stacking multiple layers of memory chips on a smaller footprint to achieve higher computational performance and energy efficiency. Air Liquide’s ultra-pure gases are fundamental to maintaining the clean environment required for developing state-of-the-art technologies.

With this investment, Air Liquide reinforces its position as a major supplier to the U.S. semiconductor industry and builds on its long-term global partnership with SK hynix, further strengthened by a recent milestone investment in South Korea. The new infrastructure allows the company to meet its customer’s needs for rapid expansion while integrating its operations into the local ecosystem.

An executive at SK hynix commented that as development begins on America’s first advanced packaging facility for HBM, the company is pleased to partner with key industry leaders to build a robust semiconductor ecosystem in Indiana. A member of Air Liquide’s Group Executive Committee noted that this milestone investment underscores the company’s ability to support the growth of its long-standing strategic partners and accelerate the development of AI technologies, relying on its three-decade presence in the U.S. electronics sector.
