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

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. If you design chips for automotive, industrial sensors, or embedded control, you now have a second foundry option coming online in 2028 — but only at 90nm, where TSMC and GlobalFoundries already have mature capacity. Tata's real value will be custom silicon at scale for India's domestic OEMs, not global competition.
