India's first commercial fab starts at 90nm — 28nm moves to the second phase
TL;DR
Tata says Dholera will ramp 55nm and 90nm before 28nm; reported commercial production shifts to mid-2028.
India's first commercial semiconductor foundry is set to start at 90nm rather than the previously highlighted 28nm node. Bloomberg reported on July 17 that Tata Electronics was preparing to begin Dholera production on mature processes before introducing 28nm.
Tata told Bloomberg that the plant covers 28nm through 110nm and that its roadmap had always started with 55nm and 90nm before 28nm. Partner PSMC said 28nm is the most advanced node in their technology package. Tata is not dropping 28nm; the dispute concerns the production sequence.
When India's Cabinet approved the project in 2024, it specifically listed 28nm high-performance-computing chips. Tata's announcement that year listed five processes, 28nm, 40nm, 55nm, 90nm and 110nm, without committing the first wafers to one node. Its May 2026 ASML release retained the same portfolio for automotive, mobile-device and AI applications.
The Dholera fab carries a planned ₹910 billion investment and capacity of 50,000 300mm wafers per month. A 2025 government release said production would begin in 2027; the July report quoted Electronics and IT Minister Ashwini Vaishnaw putting commercial production at mid-2028.
