Where it fits
Fabs run on huge volumes of nitrogen and other ultra-pure gases, usually from an on-site air-separation plant, plus small volumes of costly specialty gases (fluorine compounds, silane) and acids and solvents. Purity is measured in parts per billion.
Why it matters
This is a recurring revenue stream for as long as a plant runs. Linde is building an air-separation plant at Dholera to supply Tata's fab (due H2 2027) and has land in Sanand for an OSAT gas facility; INOX Air Products is investing ~₹500 Cr in a specialty-gas hub at Dholera and says India makes only ~10% of the gases chips need. Semicon 2.0 now pays 30% of capital cost for semiconductor-grade materials plants from ₹50 Cr.
Where the value pool sits
On-site gas contracts are long (often 15+ years) with take-or-pay terms - utility-like returns. Specialty gases and electronic chemicals carry higher margins but need purity certification.
Key drivers
New fabs and OSATs signing long-term supply deals
Semicon 2.0 materials incentive (30% of capex)
Indian fluorochemical makers moving up to electronic grades
Potential bottlenecks
Most specialty gases and electronic-grade chemicals are imported
Purity certification by each fab
Hazardous-material handling and permits
Investor metrics to watch
