Tata Semiconductor Plant, Jagiroad

The single most transformative project in the Northeast's modern history is rising on a 592-acre site at Jagiroad, about 60 km from Guwahati in Assam's Morigaon district: the Tata Semiconductor Assembly and Test (TSAT) facility, India's first indigenous, greenfield semiconductor assembly-and-test plant. Approved by the Union government with an investment outlay of around ₹27,000 crore — backed by roughly ₹14,044 crore of government incentives — it places Assam, of all places, on the global electronics map.

The plant is an OSAT facility: it takes fabricated silicon wafers and turns them into finished, packaged chips ready for use in cars, phones, data centres and consumer electronics. It will deploy three core packaging technologies — Wire Bond, Flip Chip and Integrated Systems Packaging (ISP) — with room to add advanced packaging later. At full capacity it is designed to produce up to 48 million chips a day, an astonishing figure that would make it one of the most significant such plants in the country.

The human impact is as important as the technology. The project is expected to create around 27,000 jobs — roughly 15,000 direct and 12,000 indirect — and Tata has been training a large cohort of local workers, including hundreds of women, many of whom have already joined the plant. For a state whose young people have long migrated elsewhere for work, a high-technology anchor employer of this scale is a genuine turning point, and it is already drawing an ecosystem of suppliers and skilling institutions around it.

As of late 2025 the facility had begun trial production, running at roughly a quarter of its planned capacity, with regular commercial operations expected to begin around December 2025 or early 2026. Combined with Tata's larger fabrication plant at Dholera in Gujarat, it forms the backbone of India's push for semiconductor self-reliance — and it has made 'the silicon sunrise' a real phrase in Assam.
