India Semiconductor Mission: ISM Scheme, Fab Units and PLI Explained

Quick Answer: The India Semiconductor Mission (ISM) is a flagship programme of the Ministry of Electronics and Information Technology (MeitY), approved in December 2021 with an outlay of ₹76,000 crore, to build a robust semiconductor and display manufacturing ecosystem in India. In 2024, the Cabinet expanded the outlay to about ₹1.26 lakh crore and cleared new projects, including the Tata Electronics fab at Dholera, Gujarat.

What is the India Semiconductor Mission? (Direct Answer)

The India Semiconductor Mission (ISM) is a specialized division set up under the Digital India Corporation within MeitY to drive India’s ambitions in semiconductor and display manufacturing. Launched with Cabinet approval in December 2021 under the Programme for Development of Semiconductors and Display Manufacturing Ecosystem, it carries a total outlay of ₹76,000 crore. In September 2024, the Union Cabinet approved its expansion, taking the total support to about ₹1.26 lakh crore, and cleared new semiconductor projects under the mission.

Background: Why India Needs a Semiconductor Ecosystem

Semiconductors — the tiny chips that power everything from smartphones to missiles — sit at the heart of the modern economy. India’s push for domestic chipmaking emerged from three converging pressures:

• Global chip shortage (2020–22): COVID-19 supply disruptions exposed how fragile the global semiconductor supply chain is, with lead times for chips stretching to over 50 weeks in some segments.
• Import dependence: India imports nearly all of its semiconductor requirement, with electronic goods among the largest imported items after crude oil, straining the trade balance.
• Strategic risk: Chips are essential for defence, space, telecommunications and critical infrastructure. Dependence on imports amid US–China tech rivalry and export controls (such as the US CHIPS Act era restrictions) poses national security risks.

Economically, the global semiconductor market is projected to cross $1 trillion by 2030, and India’s own electronics market is targeted to reach $300 billion, making domestic manufacturing both a growth and a security imperative.

Key Programmes Under ISM

The ISM supports four distinct components, each addressing a different stage of the semiconductor value chain:

1. Semiconductor Fabs: Financial support for setting up silicon wafer fabrication plants — the most capital-intensive stage of chipmaking.
2. Display Fabs: Incentives for manufacturing LCD/AMOLED display panels used in televisions, smartphones and laptops.
3. ATMP/OSAT Units: Support for Assembly, Testing, Marking and Packaging (ATMP) and Outsourced Semiconductor Assembly and Test (OSAT) facilities, which package fabricated wafers into finished chips.
4. Design-Linked Incentive (DLI) Scheme: Support for semiconductor design startups, including up to 50% reimbursement of eligible expenditure and deployment-linked incentives of 4–6% of net sales over five years.

Semiconductor PLI and Financial Incentives Explained

Although popularly called a “semiconductor PLI”, the ISM works primarily through fiscal support of 50% of project cost on a pari-passu basis for:

• Semiconductor fabs (for nodes 28nm and below, and mature nodes above 28nm)
• Display fabs
• ATMP/OSAT packaging units

In plain English: if a company sets up a fab costing ₹20,000 crore, the central government can support up to ₹10,000 crore of it, typically through capital expenditure reimbursement linked to milestones. This is distinct from the PLI schemes for mobile phones and IT hardware, which pay incentives as a percentage (usually 4–6%) of incremental sales of finished goods. The ISM model targets the huge upfront capital cost that keeps companies out of chipmaking, while state governments add subsidies on land, power and water on top of the Centre’s 50%.

Approved Semiconductor Projects and Fab Locations

As of 2024–25, the government has approved multiple projects under ISM — a favourite current-affairs question for competitive exams:

• Tata Electronics – Dholera, Gujarat: India’s first commercial semiconductor fabrication plant, in partnership with Taiwan’s Powerchip Semiconductor Manufacturing Corporation (PSMC). Approximate investment: ₹91,000 crore, targeting 28nm and above chips. Announced/cleared in February 2024.
• CG Power–Renesas – Sanand, Gujarat: An OSAT (packaging and testing) unit with technology partners Renesas (Japan) and Stars Microelectronics (Thailand), with an investment of about ₹7,600 crore.
• Micron Technology – Sanand, Gujarat: A ₹22,500 crore ATMP facility for memory chips, approved in June 2023 — the first major ISM project to break ground.
• Kaynes Technology – Sanand, Gujarat: A semiconductor unit (OSAT) with an investment of about ₹3,300 crore, approved in 2024, to assemble and test chips for automotive, industrial and other sectors.

Note for exams: Gujarat hosts all the initially approved units, with Dholera (a new greenfield smart city in the Delhi–Mumbai Industrial Corridor) emerging as India’s semiconductor hub. The 2024 Cabinet expansion also cleared the way for additional fabs, including proposals such as the Tata-Packaging unit in Assam (Jagiroad, Morigaon district) and the Adani–ISMC-linked proposals — the Tata OSAT unit at Jagiroad, Assam (about ₹27,000 crore) was approved alongside the Dholera fab.

Semiconductors 101: Exam-Relevant Basics

• What is a chip? A semiconductor device made from silicon (or compounds like gallium nitride) that acts as the “brain” of electronic systems — processing, storing or controlling electrical signals.
• Fabrication (Fab): The ultra-precise manufacturing of circuits on silicon wafers in cleanrooms. A fab can cost $5–20 billion to build.
• Packaging (ATMP/OSAT): Cutting the fabricated wafer into individual dies and enclosing them in protective packages, followed by testing. Less capital-intensive but labour-relevant.
• Nodes: Manufacturing process generations measured in nanometres (e.g., 28nm, 5nm). Smaller nodes mean more powerful, efficient chips; leading-edge nodes are dominated by TSMC (Taiwan), Samsung (South Korea) and Intel.
• End uses: Automotive, consumer electronics, telecom (5G), artificial intelligence, defence, space and industrial equipment.

Institutional and Policy Framework

• Nodal Ministry: Ministry of Electronics and Information Technology (MeitY).
• Implementing body: The ISM Division, set up as an independent business division within the Digital India Corporation, headed by a CEO and guided by an advisory committee of global semiconductor experts.
• Policy foundation: The National Policy on Electronics 2019 (NPE 2019), which targets positioning India as a global hub for Electronics System Design and Manufacturing (ESDM).
• Supporting legislation/structure: ISM also handles ecosystem interventions — skill development, academia-industry linkage and long-term R&D through the Chips-to-Startup programme.

Authoritative details are available on the MeitY website and via Press Information Bureau (PIB) releases on Cabinet approvals. International comparisons can be drawn from the US CHIPS for America programme (NIST).

Recent Government Approvals and Expansions

In September 2024, the Union Cabinet, chaired by Prime Minister Narendra Modi, approved the proposal for expansion of the semiconductor ecosystem with an additional outlay of ₹6,903 crore for ISM’s existing projects and cleared new initiatives. More significantly, in March 2025, the Cabinet approved the establishment of the National Semiconductor Mission (NSM) as the successor framework with a total outlay of about ₹1.26 lakh crore, and cleared the compounding mechanism for export restrictions — plus new approvals that took the count of approved units to over a dozen, including fabs by Tata Electronics (Dholera), CG Semi, Kaynes and others. Reports in 2025 also indicated approval for additional proposals such as the HCL–Foxconn OSAT unit and others under evaluation.

Exam tip: Since figures evolve, always verify the latest outlay and project list from PIB releases before your exam date. The safe, well-documented figures are: ISM 2021 outlay ₹76,000 crore; 2024–25 expansion to approximately ₹1.26 lakh crore.

Related Initiatives: PLI for Electronics and Design Ecosystem

• PLI for Large-Scale Electronics Manufacturing: Incentives of 4–6% on incremental sales for mobile phones and specified electronic components, which helped India become a major mobile phone exporter.
• Design-Linked Incentive (DLI) Scheme: Supports domestic semiconductor design companies and startups with up to 50% fiscal support for design and 4–6% of net sales as deployment incentives.
• Chips-to-Startup (C2S) Programme: A ₹2,763 crore programme to train 85,000+ engineers in VLSI and embedded system design at 300+ institutions, and nurture semiconductor startups.
• Semicon India futureDESIGN / Semicon India FutureLABS: Later additions supporting design innovation and lab-to-market product development.

Current Affairs Linkage for Science & Tech

ISM is a high-probability topic for UPSC and other exams because it sits at the intersection of Science & Technology, Economy and International Relations:

• Chip geopolitics: US–China tech rivalry, export controls on advanced chips to China, and Taiwan’s dominance (TSMC makes over 90% of the world’s most advanced chips) make semiconductor self-reliance a strategic theme.
• US CHIPS and Science Act (2022): A $52.7 billion US programme — a natural comparison question with India’s ISM.
• Quad cooperation: The Quad’s semiconductor supply chain initiative and India–US iCET (initiative on Critical and Emerging Technology) both reference semiconductor cooperation.
• India Semiconductor Conference (Semicon India): Annual event held in Gandhinagar, Gujarat, signalling India’s ambitions.
