Lithography Giant Comes Crashing Down

Supply shock hits a little-known but critical gas

A sudden squeeze on helium — the so-called “golden gas” of chipmaking — is rattling East Asian fabs and threatening key stages of semiconductor production, it has been reported. Spot prices for helium have reportedly jumped by more than 50% as buyers scramble for shipments after damage to LNG and industrial facilities in the Gulf region. Why does a gas matter so much? Because helium is used as an inert purge and cooling medium in numerous steps of wafer processing, including in lithography tool environments, and there is no practical one-to-one substitute for many of those uses.

How fabs are responding

Major South Korean manufacturers including Samsung Electronics and SK Hynix, and foundry customers such as Dongbu HiTek (东部高科), are said to be prioritizing inventory over cost, with procurement teams monitoring supplies and prices daily to avoid production interruptions. It has been reported that even if peace talks succeed, rebuilding damage at the Ras Laffan industrial zone could take years, meaning price volatility and supply risk may persist into the medium term. Qatar, which accounts for roughly one third of global helium production, is central to the problem; Korea imported 64.7% of its helium from Qatar last year, the Korea International Trade Association says.

Recovery, resilience — and geopolitics

Taiwanese foundries have made progress: TSMC (台积电) and UMC (联电) have reportedly implemented helium recycling systems that recover 60–75% of gas used in production, reducing import dependency. But roughly a quarter of daily usage still requires fresh supply, and recovery systems are energy‑intensive. Reportedly, Iran’s attack on Ras Laffan damaged LNG infrastructure and could disrupt long-term contracts — a claim that underscores how regional conflict and broader geopolitics now intersect with chip supply chains. With Western export controls and trade tensions already complicating access to advanced equipment, a commodity like helium shows how fragile and interconnected modern semiconductor supply chains really are.
