Linde, a global industrial gases and engineering company, has announced plans to invest $1 billion in the expansion of its on-site industrial gas production complex in Phoenix, Arizona. The investment follows a new long-term agreement to supply ultra-high-purity industrial gases to one of the world’s largest semiconductor manufacturers. Linde has not publicly identified the customer.
The expanded complex will support two new semiconductor fabrication facilities at the customer’s Phoenix manufacturing campus. Linde will build, own and operate two new SPECTRA® air separation units, together with the associated gas production and supply infrastructure. The new units will complement three existing air separation units already operating at the site. Once completed, the project will make the Phoenix complex one of the largest investments Linde has undertaken for an electronics industry customer globally. It will also expand the company’s capacity to supply ultra-high-purity nitrogen, oxygen and argon for advanced semiconductor production.
Linde will add two SPECTRA air separation units to its existing Phoenix industrial gas production complex to support two new semiconductor fabrication facilities.
Air separation units process atmospheric air to produce nitrogen, oxygen and argon at controlled purity levels. Linde developed its SPECTRA technology specifically to meet the ultra-high-purity nitrogen requirements of the electronics industry. The technology is designed to combine high-volume gas production with the purity, supply reliability and operating efficiency required by continuously operating semiconductor fabs.
“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.”
The U.S. investment forms part of a broader expansion supporting the same semiconductor manufacturer. Linde LienHwa, the company’s joint venture partner in Taiwan, has been selected to supply industrial gases to new semiconductor manufacturing and advanced packaging facilities at multiple sites in Taiwan. Linde LienHwa plans to invest approximately $800 million to build, own and operate several air separation units and hydrogen production units. Combined, the planned projects in Arizona and Taiwan represent approximately $1.8 billion in new gas production infrastructure supporting semiconductor manufacturing and advanced packaging capacity. Linde supplies ultra-high-purity bulk and specialty gases to electronics manufacturers in the United States, Taiwan, South Korea and other global markets.
