From the high performance computing mavens at HPC Wire, March 27:
The tightened supply of helium due to the Middle East conflict has started to expose a weak link in the AI and data infrastructure stack – helium. While most of the industry stays focused on chips and models, helium plays a small but crucial role in the manufacturing of semiconductors and cooling systems.
When chips are being manufactured, helium acts as a stable gas to keep the process as precise as possible. As helium is chemically inert (does not react with other materials), it creates a clean and controlled environment where even the smallest variations could otherwise ruin an entire batch of chips.
Helium also plays a critical role in cooling. It helps carry heat away from servers and critical components before they overheat. The chemical properties of helium make it more efficient than regular air in removing heat. It is also safer to use in high-density environments such as AI data centers that have sensitive electronics.
Helium is used during wafer fabrication in processes such as plasma etching and chemical vapor deposition. It is also used for heat transfer and backside wafer cooling, enabling uniform temperature control during lithography and other high-precision steps. In simple terms, helium helps keep modern data centers running, from making computer chips to keeping servers from overheating.
Commenting on the supply risk for helium, the Semiconductor Industry Association wrote in 2023 that “helium’s unique properties as an inert gas and a high thermal conductor make it ideal for use in functions that require preventing unwanted chemical reactions and ensuring control and precision of wafer temperatures.”
As HPC systems push toward higher density and performance, even small disruptions in cooling or chip supply can ripple across research workloads, AI training clusters, and national supercomputing facilities. These systems run at extreme power density, where even small inefficiencies in cooling can quickly impact performance and stability....
