Introduction
Semiconductors and critical minerals have emerged as the 21st-century equivalent of crude oil, transforming compute capacity and hardware control into the primary levers of statecraft, economic sovereignty, and military deterrence. With Taiwan manufacturing over 60% of all semiconductors and approximately 90% of sub-10nm advanced logic chips, global technological supply chains suffer from dangerous geographic concentration and vulnerability to geopolitical disruption.
Strategic Importance of Semiconductors
Semiconductor devices underpin virtually all modern civilian and military infrastructure, dictating a country's economic and defense posture in several ways:
- National Security and Defense: Advanced silicon powers electronic warfare systems, secure communications, aerospace avionics, and precision-guided munitions. Relying on foreign supply chains creates critical vulnerabilities to cyber backdoors, trojans, and strategic embargoes during conflicts.
- Economic and Technological Sovereignty: Semiconductors are foundational to artificial intelligence, 5G/6G telecommunications, quantum computing, and electric vehicles. India's domestic semiconductor consumption is projected to cross $100 billion by 2030, making domestic production vital to avoid widening trade deficits.
- Geopolitical Hedging: A resilient domestic semiconductor supply shields against weaponised trade restrictions, unilateral export curbs, and unexpected disruptions in the Taiwan Strait.
India's Key Initiatives in Chip Manufacturing
Recognising the vulnerability of total import dependence, India has instituted proactive policy frameworks to catalyze a domestic semiconductor ecosystem:
- India Semiconductor Mission (ISM): Initially launched with an outlay of ₹76,000 crore and augmented under ISM 2.0 to ₹1.27 lakh crore, the mission provides 50% uniform central fiscal support on a project-cost basis for semiconductor fabs, display fabs, and packaging facilities.
- Commercial Foundry Approvals: Approval and construction of commercial fabs, notably the ₹91,000 crore Tata Electronics joint venture with Taiwan's Powerchip Semiconductor Manufacturing Corporation (PSMC) at Dholera, Gujarat, focusing on mature 28nm to 110nm nodes.
- ATMP and OSAT Facilities: Fast-tracked approvals for Assembly, Testing, Marking, and Packaging (ATMP) and Outsourced Semiconductor Assembly and Test (OSAT) plants by players like Micron, CG Power, and Kaynes to capture high-value packaging segments.
- Design and Talent Ecosystem: The Design-Linked Incentive (DLI) scheme and the Chips to Startup (C2S) initiative aim to nurture indigenous fabless design start-ups and upskill engineers, leveraging India's existing 20% share of global chip design talent.
- Plurilateral Tech Partnerships: Strategic collaboration under the US-India Initiative on Critical and Emerging Technologies (iCET), the Quad Semiconductor Supply Chain Initiative, and bilateral memorandums of understanding with Japan and the European Union.
Key Challenges in Establishing Domestic Fabrication
Despite significant policy momentum, establishing leading-edge semiconductor fabrication units involves severe structural bottlenecks:
- Prohibitive Capital Intensity and Obsolescence: Setting up a greenfield semiconductor fab requires $10–15 billion in upfront capital expenditure. Because technology nodes become obsolete every 24 to 36 months, sustained reinvestment is essential even after public subsidies lapse.
- Stringent Infrastructure Demands: Fabs demand millions of gallons of ultra-pure water daily and an uninterrupted, millisecond-stable power supply. Minor fluctuations in power frequency or water contaminants can ruin entire silicon wafer runs.
- Absence of Upstream Supply Chains: India completely lacks the domestic upstream ecosystem required for fabrication, including semiconductor-grade chemicals, ultra-pure gases, photoresists, silicon ingots, and extreme ultraviolet (EUV) photolithography machinery supplied by global monopolies like ASML.
- Shop-Floor Process Engineering Deficit: Although India possesses roughly one-fifth of the world's front-end VLSI chip design engineers, it suffers an acute shortage of clean-room operational technicians, process metallurgists, and chemical fabrication specialists.
Conclusion
To build an enduring semiconductor ecosystem, India must strategically focus on mature trailing nodes (28nm–65nm) tailored for automotive, energy, and industrial IoT applications rather than engaging in a high-risk race for sub-5nm nodes. Strengthening OSAT and packaging capabilities alongside plurilateral 'friend-shoring' through mechanisms like iCET will ensure both supply chain resilience and national technological autonomy.
