Helium Shortage Hits Chip Yields
A global helium shortage is causing 15-20% yield drops in semiconductor manufacturing, where the gas is critical for lithography cooling. A 72-hour outage reportedly cost Samsung $300 million in 2024, highlighting a significant and often overlooked supply chain vulnerability.
The semiconductor industry's demand for helium is projected to increase more than fivefold by 2035, driven by government initiatives like the US and EU Chips Acts aimed at boosting domestic production. This surge in demand is occurring as the global helium market is already facing supply constraints and price volatility. Helium's exceptional thermal conductivity and inert nature make it irreplaceable for the precise temperature control required during the manufacturing of advanced semiconductor nodes. As chip designs shrink, the need for effective thermal management increases, making helium even more critical for processes like lithography and wafer cooling. Currently, there are no viable alternatives for some of these high-tech applications. The global helium supply chain is vulnerable, relying on a limited number of natural gas sources, with fewer than 20 refineries worldwide capable of separating the gas. Major production comes from countries like the United States and Qatar, but geopolitical factors and unexpected plant outages have led to chronic supply challenges. Russia's ambitions to increase production have been impacted by geopolitical tensions, affecting market access. In response to supply uncertainties, some in the industry are exploring helium conservation and recycling. Semiconductor fabrication plants can achieve recycling efficiency rates of over 95%. Companies like Lam Research are actively working to reduce helium consumption in their equipment to mitigate the impact of price hikes and shortages on production throughput.
