Helium-Free Semiconductor Process Alternatives Platform
P6/10March 14, 2026
WhatA materials science company developing drop-in replacement gases and processes that eliminate helium dependency in semiconductor manufacturing for cooling, purging, and chamber cleaning.
SignalThe chip industry treats helium as irreplaceable across multiple fab processes, but the recurring supply shocks suggest the real opportunity is eliminating the dependency entirely rather than just securing more supply.
Why NowRepeated geopolitical disruptions to helium supply combined with helium's status as a finite non-renewable resource are finally making fabs willing to invest in process changes they previously considered too risky.
MarketGlobal semiconductor gases market ~$10B; helium replacement could capture $1-3B. No focused startup competitor exists — incumbents profit from selling helium, not replacing it.
MoatPatents on novel process chemistries plus qualification data from fab partnerships create a multi-year barrier to entry.
