# Insatiable Helium Demand of EUV Lithography

A critical, counter-intuitive dynamic in the semiconductor industry is that as chips become more advanced, their reliance on helium increases dramatically — see [[contrarian-advanced-chips-more-vulnerable]].

The most advanced fabs — those producing High Bandwidth Memory (HBM) and cutting-edge logic chips for AI accelerators — rely on Extreme Ultraviolet (EUV) lithography machines built by [[entity-asml]]. These machines must operate in near-perfect vacuums to prevent the EUV light from being absorbed by air. Helium is required in massive quantities to constantly test the seals of these vacuum chambers; because helium is the smallest element, it leaks through imperfections before any other gas, serving as an early warning system.

**A single 300mm EUV fab can consume between 5,000 and 20,000 cubic meters of helium per month.** (SEMI 2024 data referenced in the enrichment overlay corroborates a 5,000–15,000 m³/month range, with shortages capable of cutting yields 10–20%.)

Consequently, the push for more powerful AI chips directly exacerbates the vulnerability to helium supply shocks. This is also why a fully native [[concept-chinese-native-chip-stack]] hinged on the Guangdong plant achieving 6N purity — that is the threshold required to feed ASML-class machines.
