Linde to invest $1 billion in Phoenix on-site gases complex for semiconductor expansion

Key highlights
  • Linde will invest $1 billion to expand its on-site industrial gases complex in Phoenix to support a major semiconductor customer.
  • The company will build, own and operate two new SPECTRA® air separation units, complementing three existing ASUs on site.
  • Expansion increases supply of ultra-high-purity nitrogen, oxygen and argon to support two new semiconductor fabrication facilities.
  • Linde LienHwa, the Taiwan JV, plans to invest about $800 million to supply ASUs and hydrogen units to the same customer at multiple Taiwan sites.

Agreement and investment

Linde has been awarded a long-term agreement to supply ultra-high-purity industrial gases to one of the world’s largest semiconductor manufacturers and will invest $1 billion to expand its existing on-site industrial gases complex in Phoenix, Arizona.

Scope and technical build

Under the agreement Linde will build, own and operate two new SPECTRA® air separation units (ASUs) and associated infrastructure, which will complement three existing ASUs at the site. The expansion increases supply of ultra-high-purity nitrogen, oxygen and argon to support two new semiconductor fabrication facilities and is intended to deliver the purity, reliability and operating efficiency required for advanced semiconductor manufacturing.

Taiwan programme

Separately, Linde LienHwa, Linde’s joint venture partner in Taiwan, was selected by the same customer to supply industrial gases to new semiconductor manufacturing and advanced packaging facilities at multiple Taiwan sites and plans to invest approximately $800 million to build, own and operate several ASUs and hydrogen production units.
