Linde has secured a long-term agreement to supply ultra-high-purity industrial gases to one of the world’s largest semiconductor manufacturers, supporting a major expansion in Phoenix, Arizona.

As part of the deal, Linde will invest around $1 billion to scale up its existing on-site gases complex in Phoenix. The move will turn the facility into one of the company’s largest global investments tied to a single electronics customer.
To meet rising demand, Linde will build, own, and operate two new SPECTRA® air separation units (ASUs), along with supporting infrastructure. These units will complement the three ASUs already operating at the site, significantly boosting capacity.
The expansion is aimed at supplying ultra-high-purity nitrogen, oxygen, and argon for two new semiconductor fabrication plants. The company said its SPECTRA® technology will ensure the levels of purity, reliability, and efficiency required for advanced chip manufacturing.
In a parallel development, Linde LienHwa — the company’s joint venture in Taiwan has also been selected by the same customer to supply industrial gases for new semiconductor fabs and advanced packaging facilities across multiple sites in Taiwan.
The joint venture plans to invest approximately $800 million to build and operate additional ASUs and hydrogen production units.
Leadership Comment
“Advanced semiconductor manufacturing depends on the reliable supply of gases at exceptional levels of purity,” said Armando Botello, President Linde Gases, US. “As global demand for advanced semiconductors continues to increase, this investment demonstrates Linde’s ability to deliver the purity, reliability and scale our customers require. We are proud to support our customer’s expansion in the United States and Taiwan and to further strengthen our long-term global relationship.”
