Tata Semiconductor Assembly and Test (TSAT)
Tata Semiconductor Assembly and Test Pvt Ltd | Assembly & Packaging
India’s first semiconductor facility in the Northeast. Demonstrates that chip manufacturing isn’t limited to Gujarat.
What does this facility make?
Assembles and tests semiconductor chips at high volume — 48 million chips per day at full capacity. Handles multiple packaging formats for diverse end markets.
Why does it matter?
Locating a major semiconductor facility in Assam is a deliberate industrial policy choice. It brings high-tech jobs and supply chain development to the Northeast, a region that has historically been bypassed by India’s manufacturing boom. The Rs.27,000 crore investment is also the largest single private-sector industrial investment in the Northeast.
