India designs chips. We've done so for decades — Intel, Qualcomm, AMD, and dozens of other chip companies have major design centers in Bangalore 302 Hyderabad, where Indian engineers contribute to some of the most advanced processors in the world. What India doesn't do is manufacture chips. The fabs — the billion-dollar factories where silicon wafers become processors — are in Taiwan, South Korea, the US, and China. India has none.
The India Semiconductor Mission (ISM), launched in 2021 with a budget of ₹76,000 crore ($10 billion), aims to change that. The ambition is massive. The question is whether ambition, funding, and strategic intent can overcome the enormous technical, economic, and infrastructural challenges of building a semiconductor manufacturing ecosystem from scratch.
What's Actually Happening
Tata Electronics + PSMC (Taiwan): The most advanced project — a semiconductor fab in Gujarat's Dholera Special Investment Region. This facility will manufacture chips at the 28nm node initially, which is several generations behind the cutting edge (TSMC makes 3nm chips) but is widely used for automotive, IoT, and industrial applications. The fab is expected to begin production by 2026-2027.
Micron's ATMP facility: Micron Technology is building an Assembly, Test, Marking, and Packaging (ATMP) facility in Sanand, Gujarat. This doesn't manufacture chips from silicon wafers but handles the back-end process of packaging manufactured chips into usable components. The facility represents a real entry point into the semiconductor supply chain.
CG Power and Renesas: A joint venture for a chip packaging and testing facility, also indicating the strategy of entering the semiconductor value chain through back-end processing before attempting front-end manufacturing.
The Hard Truths
Starting at 28nm is realistic, not embarrassing. The cutting edge (3nm, 2nm) is dominated by TSMC and Samsung because they've invested hundreds of billions of dollars over decades. India can't leapfrog to the frontier — that's not how semiconductor manufacturing works. Starting at mature nodes, building manufacturing expertise, developing the supplier ecosystem, and gradually advancing is the only path that has ever worked for any country.
Infrastructure challenges are real. Semiconductor fabs require massive quantities of ultrapure water, completely reliable power (a momentary blackout can destroy an entire production batch), and earthquake-resistant construction. India's industrial infrastructure, while improving, doesn't yet meet these requirements uniformly, and the Dholera facility is being built with these specifications as new infrastructure rather than existing capability.
Talent is available but needs transformation. India has excellent semiconductor design talent but very limited manufacturing talent because there's been nothing to manufacture on. Training programs are underway, but building a workforce capable of operating a semiconductor fab takes years, not months.
Why It Matters
The COVID-era chip shortage demonstrated the strategic vulnerability of depending on a handful of countries for a component that goes into everything from phones to cars to military equipment. India's semiconductor mission isn't primarily economic — it's strategic. Reducing dependence on imported chips for defense applications, critical infrastructure, and consumer electronics is a national security priority.
Even partial success — domestically manufacturing chips for automotive, IoT, and industrial applications while continuing to import cutting-edge processors — would be transformative. India imports roughly $10 billion worth of semiconductors annually. Replacing even 20-30% of that with domestic production would be significant for the trade balance and for supply chain resilience.
The semiconductor mission is a 10-15 year project, not a 3-year one. The factories being built today will take years to reach full production capacity. Judging the mission's success before the first chip rolls off a production line is premature. But the intent is clear, the investment is real, and for the first time, India is seriously attempting to participate in chip manufacturing rather than just chip design.
