India's First Chip Fab Opens at 90nm, Two Process Nodes Below What Tata Promised

India's first domestic chip fab, operated by Tata Electronics with PSMC technology transfer, will begin production at 90nm rather than the promised 28nm, with commercial output delayed 18 months to mid-2028. The downgrade reflects manufacturing reality: starting at a mature node reduces yield risk and lets Tata's teams build foundry expertise before attempting the far more complex 28nm process.
