India's Semiconductor Mission: $10 Billion Bet on Becoming a Chip Nation

India's $24 billion annual semiconductor import bill is not merely an economic vulnerability—it is a national security concern. Every advanced weapons system, every telecom network, every data centre, and every modern vehicle in India depends on chips manufactured overwhelmingly in Taiwan (TSMC), South Korea (Samsung, SK Hynix), or China. The COVID-19 pandemic exposed this dependency catastrophically: global chip shortages shut down India's automobile factories in 2021, with Maruti Suzuki and Tata Motors losing production of over 200,000 vehicles collectively. The broader strategic calculus is even starker: if China were to invade Taiwan—a scenario that US and Indian intelligence agencies assess as a realistic possibility by 2027-2030—India's electronics manufacturing, defence systems, and digital infrastructure would face potentially catastrophic supply disruptions within six months. Building domestic semiconductor capacity is therefore framed by Indian policymakers not as industrial ambition but as existential strategic necessity, on par with nuclear self-sufficiency in the 1970s.

The Cabinet-approved semiconductor investments represent a calibrated starting point rather than a comprehensive solution. Tata Electronics' partnership with Taiwan's PSMC for a 28nm fab in Dholera, Gujarat, with a total investment of ₹91,000 crore ($11 billion), is the flagship project. The 28nm node produces chips used in automotive electronics, industrial IoT devices, power management ICs, and older-generation connectivity chips—not cutting-edge AI accelerators, but essential for the broad base of electronics India seeks to manufacture. Micron Technology's ATMP facility in Sanand, receiving ₹11,000 crore in government support against a total investment of $2.75 billion, is more immediately viable: packaging and testing semiconductor chips requires less advanced technology than fabrication and can be operationalised within 18-24 months. Keynes Semiconductor's compound semiconductor fab in Sanand focuses on power electronics and radio frequency chips, targeted at India's growing defence electronics and renewable energy inverter markets.

Honest assessment demands acknowledging the scale of India's technological deficit in semiconductors. Taiwan's TSMC has spent 40 years building semiconductor expertise across 10,000 process steps, with a supplier ecosystem of over 600 companies providing specialised chemicals, gases, equipment, and materials. South Korea's Samsung and SK Hynix have similarly deep ecosystems. India has none of this: no photolithography expertise, no semiconductor-grade chemical supply chain, no experienced process engineers at scale. The 28nm node that India is targeting was cutting-edge in 2011 and is now considered mature technology—useful for many applications but not competitive in high-performance computing, advanced mobile processors, or AI chips. TSMC's current leading edge is 2-3nm. India's semiconductor engineers, trained primarily in chip design rather than fabrication, will require 5-7 years of hands-on experience before the planned fabs can operate at full efficiency. The risk of a technology transfer deficit—where equipment and process knowledge are transferred on paper but not embedded in human capital—is significant.

The three approved semiconductor projects are projected to create 20,000 direct jobs and 60,000 indirect jobs. While modest compared to India's annual addition of 8 million new labour force entrants, these are high-quality, high-wage jobs: semiconductor engineers and technicians earn 3-5 times India's manufacturing average wage. More significant is the industrial ecosystem that semiconductor manufacturing catalyses. South Korea's experience shows that a chip industry generates dense supplier clusters in chemicals, precision engineering, and equipment manufacturing—multiplier effects that India's relatively hollow manufacturing ecosystem desperately needs. Export potential is harder to quantify at this stage. ATMP services are immediately exportable: India can compete on cost with existing ATMP hubs in Malaysia, Vietnam, and Thailand, which currently handle packaging for TSMC, Intel, and AMD wafers. Micron has already indicated that its India ATMP output will be exported globally, making it India's first meaningful semiconductor export operation.

India's semiconductor ambitions face execution risks on multiple fronts. Land acquisition for the Dholera fab site encountered delays of over 14 months due to compensation disputes with 23 villages. Water access—semiconductor fabrication is enormously water-intensive, requiring ultra-pure water at volumes of 2-4 million gallons per day—requires infrastructure investment that Gujarat is still building. The global semiconductor investment cycle also introduces risk: if TSMC's Arizona fab (also delayed and over budget) struggles to operate profitably, investor appetite for greenfield semiconductor investments in countries with even less established ecosystems may decline. The geopolitical dimension adds urgency. The US has actively encouraged India's semiconductor ambitions as part of its Indo-Pacific strategy, and the 2023 India-US iCET framework explicitly prioritises semiconductor collaboration. TSMC's participation in the India fab, even though its own operations remain entirely in Taiwan, reflects Taipei's calculation that supporting India's semiconductor ambitions strengthens the quad alliance's resilience against Chinese coercion.
