Current obstacles

Supply chain localizationMost equipment and chemicals come from US, Japan, Taiwan; building local suppliers is slow.
Workforce expertiseManufacturing requires thousands of trained engineers; India's industry is nascent.
Export controls and geopolitical riskAdvanced tools face US controls; India's geopolitical position may limit cutting-edge access.

Physics limits

Yield learning curveWorld-class yields (>95%) take 2–3 years learning; early fabs have higher defects and costs.
Time to advanced nodes28nm and below need leading-edge equipment and R&D; 90nm→7nm took TSMC 15+ years.

How it works

3 parts

Partnership Model

Tata-PSMC collaboration

PSMC provides technology licensing, design support, and engineering expertise; Tata remains the operator and owner.

Phased Approach

Conservative technology roadmap

Starting at 90nm–55nm builds yield expertise before advancing to newer nodes.

Capacity Growth

Multi-phase expansion

Phase 1: 50k wafers/month; Phases 2–3 will triple capacity to 150k+ monthly.

About Tata Electronics

The team behind Dholera Fab

Tata Electronics

Semiconductor foundry, Dholera fab, India, 90nm PSMC

Tata Electronics is building India's first commercial semiconductor fab in Dholera, partnering with Taiwan's PSMC. Starting at 90nm and 55nm, targeting production mid-2028.

Tata Electronics (est. 2020) leads India's bid for domestic chip production with the Dholera fab in partnership with Taiwan's PSMC.
₹91,000 crore ($11B) investment, India's largest semiconductor project; reaches 50k wafers/month at full capacity.
Starting conservatively at 90nm and 55nm in mid-2028; 28nm and below planned as later upgrades.
