India Semiconductor Mission: Geopolitics of Chip Manufacturing

Semiconductors—often referred to as the "brains" of modern electronics—have emerged as the defining technology of the 21st century. From smartphones and electric vehicles to guided missiles, medical devices, and artificial intelligence infrastructure, semiconductor chips underpin virtually every facet of modern industry and national security.

Recognizing the strategic necessity of domestic chip production, the Government of India launched the India Semiconductor Mission (ISM) in December 2021 with an initial outlay of ₹76,000 crore (approximately $10 billion). This initiative represents not merely an industrial policy, but a critical strategic intervention aimed at securing India’s technological sovereignty amidst shifting global weaponized interdependencies and weaponized supply chains.

Historical Background and Context

1. India's Past Attempts at Semiconductor Manufacturing

India’s quest for semiconductor self-reliance is not new. In 1984, the government established the Semiconductor Complex Limited (SCL) in Mohali, Punjab. At the time, SCL was technologically comparable to global peers in East Asia. However, a catastrophic fire in 1989, coupled with bureaucratic delays, lack of sustained capital expenditure, and the economic liberalization of 1991 (which prioritized software over hardware), led to India falling behind global semiconductor manufacturing curves.

Subsequent policy attempts in 2006 and 2013 to attract global foundries failed due to rigid policy frameworks, high capital requirements, inadequate infrastructure support (uninterrupted power and ultrapure water), and lack of an integrated domestic ecosystem.

2. The Global Supply Chain Landscape

The global semiconductor value chain is one of the most complex, specialized, and geographically concentrated supply chains in human history. No single nation possesses a complete end-to-end domestic supply chain:

• Intellectual Property & Design: Dominated by the United States (Cadence, Synopsys, Qualcomm, Nvidia) and Europe (ARM).
• Photolithography Equipment: Monopolized by the Netherlands (ASML holds a near 100% monopoly on Extreme Ultraviolet Lithography - EUV equipment).
• Raw Wafers & Chemicals: Dominated by Japan (Shin-Etsu, SUMCO) and South Korea.
• Front-end Fabrication (Foundries): Heavily concentrated in Taiwan (TSMC produces over 60% of global foundry chips and 90% of advanced sub-7nm chips) and South Korea (Samsung).
• Back-end Assembly, Testing, and Packaging (ATP/OSAT): Concentrated in China, Taiwan, Malaysia, and Vietnam.

3. The "Chip War" and Geopolitical Catalysts

The vulnerabilities of this hyper-concentrated supply chain were exposed by three key developments:

1. COVID-19 Pandemic: Lockdowns disrupted global supply chains, causing severe shortages in automobile and consumer electronics sectors worldwide.
2. Cross-Strait Tensions: Taiwan’s concentration of advanced fabrication creates a critical vulnerability. Any conflict across the Taiwan Strait could halt global technology production—a concept known as Taiwan’s "Silicon Shield".
3. US-China Tech War: The United States introduced the CHIPS and Science Act (2022) and sweeping export controls to deny China access to advanced computing chips, EDA software, and EUV lithography tools. China responded by expanding its dominance in legacy/mature nodes (28nm and above) and restricting critical raw materials like Gallium and Germanium.

Key Features and Objectives of the India Semiconductor Mission (ISM)

Launched under the aegis of the Ministry of Electronics and Information Technology (MeitY) within the Digital India Corporation, the ISM acts as the nodal agency for driving India's semiconductor and display manufacturing ecosystem.

2. De-Risking and the "China Plus One" Strategy

Global tech firms are seeking to diversify beyond China and Taiwan to manage geopolitical exposure. India presents a compelling alternative due to its vast internal market, large engineering workforce, and stable political environment. By de-risking assembly and packaging away from East Asia, global firms find a strategic partner in India.

3. Strategy of Mature Nodes vs. Cutting-Edge Nodes

While global headlines focus on sub-3nm nodes powering advanced AI GPUs, over 70% of industrial, automotive, telecom, and defense applications rely on mature nodes (28nm to 180nm).

• ISM’s primary strategy focuses on capturing mature node fabrication first.
• This strategy lowers capital barriers, builds domestic manufacturing experience, and serves critical local demand in automotive, IoT, and power electronics sectors before attempting leading-edge nodes.

Significance for India

1. National Security and Defense Autonomy

Modern defense equipment—radar systems, electronic warfare suits, secure satellite communications, and precision missiles—depends heavily on specialized microelectronics. Relying on imported chips leaves critical national security systems vulnerable to supply disruptions, backdoor malware, and foreign espionage during conflict. Domestic fabrication guarantees technological integrity and strategic autonomy.

2. Economic Resilience and Import Substitution

India's domestic demand for electronics is projected to surpass $400 billion by 2030. Without a domestic semiconductor base, India's chip import bill could rival or exceed its crude oil import bill, worsening the Current Account Deficit (CAD). Domestic manufacturing creates import-substitution effects and reduces foreign exchange outflows.

3. Leveraging Existing Strengths in Chip Design

India is already a global powerhouse in fabless chip design:

• Over 20% of the world's semiconductor design engineers are based in India (Bangalore, Hyderabad, Noida, Pune).
• Major global chip design firms (Qualcomm, Intel, Nvidia, Texas Instruments, AMD) operate major R&D centers in India.
• ISM's Design Linked Incentive (DLI) aims to transform India from a design service provider for foreign firms into a creator of homegrown Intellectual Property (IP).

4. Downstream Industrial Multiplier Effect

Semiconductors act as foundational inputs for high-value manufacturing:

• Automotive: Electric Vehicles (EVs) require up to three times as many chips as internal combustion engines.
• Telecom: Rollout of domestic 5G, 6G, and optical networking equipment.
• Consumer Electronics and Industrial Automation.
• Establishing fabs creates high-skilled jobs, supports local suppliers, and fosters localized innovation hubs.

Challenges and Concerns

Despite structural progress, establishing a semiconductor manufacturing ecosystem in India faces critical bottlenecks:

1. Extreme Capital Intensity and Gestation Periods

• Building a single advanced fabrication plant costs between $5 billion and $20 billion.
• Fabs require ongoing capital upgrades to keep pace with rapid technological shifts. Fiscal incentives must remain stable across changing political cycles.

2. Infrastructure Demands: Water, Power, and Logistics

Semiconductor manufacturing requires ultra-precise, uninterrupted utility inputs:

• Ultrapure Water (UPW): A standard fab consumes millions of gallons of water daily, requiring specialized purification infrastructure.
• Uninterrupted Power: A power fluctuation lasting even milliseconds can ruin an entire batch of silicon wafers, causing hundreds of millions of dollars in losses.
• Vibration-Free Logistics: Transporting delicate photolithography equipment and finished wafers demands high-grade transport infrastructure.

└───────────────────────┴────────────────────────┴───────────────────────┘

3. Supply Chain and Raw Material Dependencies

Fabs require over 300 specialized chemicals, ultra-pure gases (e.g., Silane, Arsine, Fluorinated gases), specialized raw silicon wafers, and photomasks. India currently lacks a local supply base for these high-purity inputs, leaving early fabs reliant on imported raw materials.

4. Skill Deficit in High-Tech Manufacturing

While India excels in software and fabless logic design, it lacks experienced talent in chemical processing engineering, process integration, physical device physics, and cleanroom fabrication operations.

5. Issues with the Design-Linked Incentive (DLI) Scheme

Industry feedback indicates that the DLI scheme faces friction due to strict domestic ownership clauses, caps on financial incentives, and delays in releasing funds, which has slowed uptake among early-stage startups.

Comparative Analysis: Global Chip Acts

Way Forward

To establish a resilient semiconductor ecosystem, India should adopt a phased, pragmatic policy roadmap:

1. Prioritize OSAT/ATMP Facilities: Building assembly, testing, and packaging capacity requires lower capital investment and shorter setup timelines. Developing an OSAT hub builds local ecosystem trust, establishes supplier networks, and creates immediate employment.
2. Focus on Mature Nodes (28nm and above): Rather than competing for capital-intensive 2nm/3nm technology, India should secure legacy node production to supply local automotive, industrial, consumer electronics, and IoT markets.
3. Establish Dedicated Semiconductor Parks: State governments should set up targeted zones equipped with pre-approved environmental clearances, dedicated high-voltage sub-stations, ultrapure water processing units, and zero-vibration transport links.
4. Talent Cultivation via Academic Integration: Expand the Chips to Startup (C2S) program to train 85,000 engineers in VLSI and process technology across IITs, NITs, and specialized institutes, addressing the manufacturing skills gap.
5. Strengthen International Alliances: Deepen bilateral partnerships with Taiwan, Japan, the US, and South Korea to support joint ventures, facilitate technology transfers, and integrate India into global value chains.
6. Reform the Design-Linked Incentive (DLI): Streamline eligibility criteria, ease equity ownership constraints, and provide direct subsidies for EDA tool access to foster local fabless startups.
