Inside the Dholera and Sanand Fab Corridors: Real Timelines, Water Requirements, and Packaging Realities
India’s semiconductor push has moved from policy ambition to civil works, utility planning and supply-chain triage. In Gujarat, the Dholera and Sanand corridors now carry the burden of proving whether a $10 billion incentive regime can convert land, power and water into industrial-grade chip capacity on schedule. The stakes are larger than one fab: India is trying to build a domestic electronics stack that can survive geopolitical shocks, import dependence and the capital intensity of advanced manufacturing. But the operational test is unforgiving. A 28nm fab, an ATMP line and a packaging hub each require different levels of purity, uptime and talent, and the bottlenecks are not only financial. Ultra-pure water, uninterrupted power, chemical logistics, cleanroom discipline and process engineers are the real constraints. The question in Gujarat is no longer whether India wants semiconductors; it is whether the corridor can deliver the invisible infrastructure that semiconductors demand.
