China's helium export ban rattles semiconductor supply chain already hit by West Asia crisis

The semiconductor industry is facing a new challenge as China's recent temporary ban on helium exports intensifies existing supply chain issues. This development follows disruptions linked to the US-Iran conflict, heightening worries over rising costs and potential supply shortages for chip manufacturers if the situation persists. Though helium constitutes a minor part of a chipmaker's overall operational expenses, it is crucial during various manufacturing stages. Industry analysts emphasize that there is currently no viable alternative for helium in several key semiconductor processes, making its availability vital for production stability. The ban comes after military strikes earlier this year damaged Qatar's Ras Laffan processing facilities, which are among the largest helium hubs globally. While there was initial optimism for a supply recovery post-ceasefire, China's decision to halt exports has further restricted an already tight market. Silicon may serve as the backbone of semiconductors, yet the manufacturing of advanced chips heavily relies on specialty chemicals and industrial gases like helium. This gas is essential due to its unique properties, such as high thermal conductivity and ultra-low boiling point. "Helium remains strategically critical for semiconductor manufacturing, utilized in wafer backside cooling, leak detection, and various processes critical to production," explained Manish Rawat, a semiconductor analyst at TechInsights. Despite its minimal contribution to fabrication costs, Rawat notes that helium is a single-point dependency in the supply chain. It plays a role in the production of several types of chips, including GPUs, AI accelerators, and automotive components. Its usage has surged as manufacturers transition to more advanced technologies. Danish Faruqui, CEO of Fab Economics, highlighted that the amount of helium consumed has increased significantly as processes have become more sophisticated, with demands rising from 8-10 liters per wafer to around 375 liters at leading-edge nodes. The global helium production landscape is heavily skewed, with a few countries dominating supply. Before recent conflicts, the U.S. and Qatar accounted for a substantial portion of the market, producing approximately 81 million and 63 million cubic meters, respectively. South Korea, a major semiconductor manufacturer, relied on Qatar for nearly 65% of its helium imports, underscoring the industry's vulnerability to supply disruptions. China's export restrictions are perceived as a strategy to safeguard its domestic supply rather than a direct attack on foreign chipmakers. As China tightens its grip on helium reserves to support its own AI and semiconductor fabs, it may absorb a larger share of the global supply, leaving less available for Western and Asian manufacturers. Initially, helium prices are expected to surge rather than immediate production impacts. Pre-conflict prices for semiconductor-grade helium ranged from $15-$22 per liter; however, they have now escalated to $22-$35 per liter, with spot market prices reaching $85-$110 per liter for those without long-term contracts. Fortunately, many leading semiconductor manufacturers are protected by strategic inventories and recycling systems. Advanced fabs can maintain operations for several weeks even if new supplies are interrupted, but prolonged disruptions could force difficult decisions, such as prioritizing higher-margin products or delaying maintenance and reducing output. With the semiconductor landscape continuously evolving, this helium export ban could have significant repercussions if supply disruptions last for an extended period, affecting various sectors reliant on advanced chip technologies.
