India's first front-end semiconductor fab, the Tata Electronics and Powerchip PSMC joint venture in Dholera, Gujarat, has crossed the halfway construction mark, with foundations complete and cleanroom installation and equipment calibration now underway. The ₹91,000 crore facility, designed for 50,000 wafers per month at the 28nm node with ASML deep ultraviolet lithography tools on contract, is targeting trial production in December 2026.

The ₹91,000 crore Tata Electronics and Powerchip Semiconductor Manufacturing Corporation (PSMC) semiconductor fab at Dholera Special Investment Region, Gujarat, has crossed the 50 percent construction milestone, with site foundations complete and the two most technically demanding phases of the project now underway: cleanroom installation and equipment calibration. The milestone, reported in August 2026, keeps the plant on track for its target of trial production in December 2026, which would make Dholera the first front-end wafer fabrication facility to go operational in India and one of a very small number of new national fabs commissioned anywhere in the world in the 2020s.
The Dholera fab is designed for an initial production capacity of 50,000 wafers per month at the 28-nanometre technology node, using ASML's deep ultraviolet (DUV) lithography tools, which are now confirmed on contract following the strategic partnership agreement signed between Tata Electronics and ASML in May 2026. The 28nm to 110nm node range targeted by the facility covers a broad swath of the global semiconductor market: automotive-grade microcontrollers, power management ICs, display driver chips, connectivity semiconductors for WiFi and Bluetooth, and industrial sensors. These segments collectively represent hundreds of billions of dollars in annual global semiconductor demand and are areas where supply chain diversification away from Taiwan has been a priority for major OEM customers.
Cleanroom installation and equipment calibration are the most technically sensitive phases of a semiconductor fab construction project. The cleanroom environment, typically an ISO Class 3 or 4 environment for leading-edge fab operations, must maintain ultra-low particle counts, precise temperature and humidity control, and vibration isolation to levels that are achievable only with purpose-built infrastructure. Equipment calibration involves the complex process of aligning, characterising and qualifying each process tool — lithography systems, etch chambers, deposition reactors, and metrology stations — to produce wafers within the tight tolerances required for commercial production.
Taiwan's Powerchip Semiconductor Manufacturing Corporation brings wafer fabrication process technology to the venture that has been developed over decades of mature-node foundry operations. PSMC operates fabs at 12-inch and 8-inch wafer scales in Taiwan and has established customer relationships with automotive and industrial chip designers that align with the Dholera facility's target market focus. The Tata-PSMC joint venture structure gives Tata Electronics access to PSMC's process IP, workforce training, and customer pipeline while PSMC gains a capital-subsidised manufacturing footprint outside Taiwan.
The Dholera fab has received approval under the India Semiconductor Mission with a capital support commitment that covers a significant portion of the total ₹91,000 crore investment. The ISM subsidy structure, combined with Tata Group's equity commitment and PSMC's technology licensing arrangement, makes the Dholera fab's economics competitive with comparable mature-node foundry investments in Southeast Asia and Europe when the full subsidy value is factored into the project cost model.
The December 2026 trial production target refers to the first wafers being processed through the full fab line in qualification mode, not the start of commercial volume production. After trial wafers confirm that each process step is meeting specification, the fab enters a yield ramp phase typically lasting 6 to 12 months, during which process optimisation work brings defect density down to levels that support commercial economics. Full commercial production at Dholera is therefore most likely in the 2027 to 2028 timeframe, but the December 2026 milestone will establish India as a country with a working front-end semiconductor fab for the first time.
