Iran war triggers helium shortage, hits semiconductor supply

"Semiconductor-grade helium is essential for chipmakers to maintain ultraclean and ultracold manufacturing environments. This contaminant-free helium is also needed for energy and heat transfer, and in vacuum chambers. There is no alternative to ultra-high-purity helium for these chipmaking processes and without it, fabrication will slow down or even come to a halt."

"A prolonged shortage of helium could lead to a shortfall of advanced chips and have knock-on effects for electronics manufacturers who depend on them, or force others to scale back their datacenter plans."

"Helium is expensive relative to other gases, so, for the most part, where there are substitutes for helium, helium is no longer used. Where helium remains irreplaceable, such as in semiconductor manufacturing, the shortage creates significant supply chain vulnerability."

Helium shortage has emerged as a critical global supply chain bottleneck alongside oil and gas concerns, particularly affecting semiconductor manufacturing. Helium serves multiple industrial applications including MRI scanning, optical fiber manufacturing, welding, and leak detection. However, the semiconductor industry faces the most significant pressure due to its dependence on semiconductor-grade helium for maintaining ultraclean and ultracold manufacturing environments. Ultra-high-purity helium is essential for energy and heat transfer in vacuum chambers during chip fabrication. No alternative materials exist for these specialized chipmaking processes, making helium irreplaceable. A prolonged shortage could reduce advanced chip production, impacting electronics manufacturers and forcing datacenter expansion delays.
