The Helium Beneath the Photoresist Crunch

The Helium Beneath the Photoresist Crunch

Ras Laffan Industrial City in late February 2026 knocked offline roughly 30% of global semiconductor-grade helium supply in a matter of days. Every other outlet has spent the last two weeks writing about naphtha and photoresist. Those stories are real. They're also the wrong headline, because the naphtha crunch has a ceiling and the helium crunch does not.

The attacks on Ras Laffan destroyed the LNG processing infrastructure that a meaningful fraction of the world's semiconductor fabs depend on for a gas they cannot substitute. Helium cools the optics in EUV lithography machines. It pressurizes the chipmaking process. It is not a chemical you can reformulate when supply tightens. You need more of it, from somewhere, at the right purity, or your fab stops making sense.

Ras Laffan's LNG processing capacity will not come back online in months. It will not come back online when the shooting stops. Ras Laffan LNG repairs are expected to take up to five years, driven not by funding constraints but by a global turbine shortage. These are not ordinary industrial components — they are precision machines built to spec, with lead times that run years regardless of how much money you throw at the problem. The global turbine market does not have surge capacity. It never has. Even if a ceasefire were signed tomorrow, the repair timeline is a function of supply chains that cannot be accelerated by political will.

Helium spot prices have already surged 40–100% after the Ras Laffan attacks. That is the opening move. Morningstar's David Roche estimates full supply chain recovery at four to six additional months beyond the disruption period, and that estimate assumes the photoresist and naphtha lines normalize — not that the helium does. For the advanced fabs running EUV lithography, the bottleneck is structural. TSMC's most advanced fabs consume roughly 500,000 cubic feet of helium per year, and there is no spare global capacity to absorb a 30% demand shock when Qatar's output drops offline for half a decade.

The photoresist story — naphtha feedstock disruptions, Japanese specialty chemical shortages, propylene glycol methyl ether (PGME) and propylene glycol methyl ether acetate (PGMEA) supply constraints — is real and visible, and it will get more coverage because it is easier to explain and easier to picture. Six of Japan's twelve naphtha cracking centers have already reduced output. Spot prices for Japanese naphtha surged from around $600 per ton before the disruption to $1,190 in early April. Korean suppliers Chemtronics and Jaewon Industrial have established mass production systems for PGMEA and already supply Samsung Electronics. None of this is nothing.

But requalification for process material changes takes about a year, and even longer for leading-edge nodes. The requalification lag means the photoresist constraint is already locked into the 2027 accelerator roadmap. Nothing done in the next twelve months can qualify a new photoresist supplier fast enough to matter for leading-edge nodes. The bottleneck is not the political disruption — it is the infrastructure response time, and the infrastructure response time for helium is measured in years, not months.

Israel and Jordan together supply approximately two-thirds of global bromine production, another input with concentrated geography. Samsung Electronics and SK Hynix are especially vulnerable because their memory and logic supply chains are centralized in ways that fabs with more diversified supplier networks are not. AI accelerators, data-center chips, and automotive semiconductors may face delays or price hikes — that much is in every wire story. What is not in every wire story is that the delay is already baked in, that the price hikes are the floor not the ceiling, and that helium will remain a constraint long after Hormuz reopens and naphtha flows resume.

With the Strait of Hormuz effectively closed since early March, supplies of naphtha have been sharply curtailed. Produced during the refining of crude oil or natural gas, naphtha is essential to the manufacture of advanced chips. Major Japanese photoresist suppliers had warned both firms of looming disruptions. The shortage is expected to hit advanced nodes that rely on extreme ultraviolet (EUV) lithography the hardest due to process sensitivity and tight tolerances.

The photoresist story is about a supply chain under pressure. The helium story is about a supply chain that does not exist in enough volume to replace what was lost. These are different problems with different timelines. The chip industry has spent decades building redundancy out of its manufacturing processes. It did not build redundancy into its helium supply, because nobody expected Qatar's industrial heart to come under sustained attack. The shortage will outlast the war that caused it. That is the story underneath the story.

AI chip designers and procurement teams who think the photoresist crunch eases when Hormuz reopens are planning based on the wrong timeline. The requalification bottleneck means the constraint is already baked into the 2027 accelerator roadmap. Spot prices for helium will remain elevated as traders arbitrage remaining supply. Long-term contracts will reprice. Fabs that secured preferential helium terms will have a material advantage over those that did not. The next eighteen months will reveal which companies hedged the right risks — and which ones woke up to a supply problem they thought was temporary.

It is not temporary.
