Overview

A semiconductor is a material whose electrical conductivity can be precisely controlled, enabling transistors and integrated circuits that perform computation, memory, sensing, communication and power management.

Strategic foundation: Chips underpin telecommunications, artificial intelligence, automobiles, medical devices, energy systems, defence platforms and digital public infrastructure.
Technological self-reliance: Self-reliance does not mean producing every chip domestically; it means securing trusted access, retaining critical design and manufacturing capability, diversifying dependencies and becoming indispensable in selected value-chain segments.
India’s opportunity: India combines a large electronics market, software and design talent, public incentives and trusted international partnerships.
India’s vulnerability: A large share of domestic chip demand is still met through imports, while fabrication depends on concentrated global supplies of equipment, materials, intellectual property and process know-how.
Why resilience is a better goal than autarky
The semiconductor value chain is globally specialised and extraordinarily capital-intensive. India should therefore build domestic depth in strategic segments while maintaining diversified technology partnerships, export markets and reciprocal supply-chain relationships.

How the Semiconductor Value Chain Works

The chip ecosystem is a sequence of design, wafer fabrication, assembly, packaging, testing and integration, supported by highly specialised equipment, materials and intellectual property.

Architecture and product definition: Firms decide what the chip must do, its performance, power, cost and security requirements.
Electronic Design Automation and IP blocks: Engineers use specialised software and reusable designs to build and verify the circuit.
Tape-out: The final verified design is sent for mask preparation and fabrication.
Wafer fabrication: Hundreds of precise deposition, lithography, etching, doping and cleaning steps create transistors and interconnects on silicon or compound-semiconductor wafers.
Why fabrication has high entry barriers
A fab requires very high capital expenditure, uninterrupted power and ultrapure water, process discipline, supplier proximity and consistently high yield. Commercial success depends as much on manufacturing learning and utilisation as on the construction of the facility.
Assembly, Testing, Marking and Packaging: Individual dies are cut, connected, enclosed and tested; advanced packaging increasingly integrates multiple dies or chiplets for system-level performance.
Outsourced Semiconductor Assembly and Test: Independent OSAT companies provide packaging and testing at scale.
Compound semiconductors: Materials such as silicon carbide and gallium nitride offer advantages in power electronics, radio-frequency systems and harsh environments.
Equipment and materials: Lithography systems, deposition and etching machines, gases, chemicals, substrates, photoresists and specialty materials form critical upstream dependencies.
Deployment: Chips create value only after integration into products such as vehicles, phones, industrial systems and strategic platforms.

Applications

Semiconductors are general-purpose technological inputs whose performance and trustworthiness affect both civilian productivity and national security.

Digital economy: Processors, memory and connectivity chips power computers, smartphones, cloud systems and data centres.
Artificial intelligence: Accelerators and high-bandwidth memory enable model training and inference.
Telecommunications: Radio-frequency, baseband, optical and network chips support 5G and future 6G systems.
Mobility: Vehicles use microcontrollers, sensors and power semiconductors for safety, infotainment, batteries and electric drivetrains.
Energy transition: Power electronics manage solar inverters, grids, charging systems and industrial motors.
Healthcare: Sensors, imaging equipment, wearables and diagnostic devices depend on reliable chips.
Defence and space: Trusted, secure and radiation-tolerant devices are essential for guidance, communication, surveillance and satellites.
Dual-use implication
The same advances that improve commercial computing and connectivity can strengthen military, cyber and surveillance capability. Policy must therefore combine innovation with export controls, trusted supply chains, cybersecurity and rights-respecting deployment.

India’s Ecosystem and Capability

India’s semiconductor strategy is moving from initial ecosystem creation to deeper capability across design, manufacturing, packaging, materials, research and talent.

Semicon India Programme: Launched in December 2021 with an outlay of ₹76,000 crore to support fabs, display manufacturing, compound semiconductors, packaging and design.
India Semiconductor Mission: Operates as the nodal agency for appraisal, recommendations, implementation oversight and ecosystem development.
Semicon 2.0: Approved with a total outlay of ₹1,27,500 crore and operationalised through six pillars covering design, machines and materials, more fabs, ATMP/OSAT, research and development, and talent. Cabinet approval, 15 July 2026
What changes under Semicon 2.0
The second phase seeks depth beyond large fabrication incentives by supporting design ownership, deployment, equipment, materials, advanced packaging, R&D and human capital. Applications are initially open for three years, supported projects generally run up to six years, and a mid-term assessment is planned after three years.
Approved manufacturing base: As of June 2026, 12 projects worth about ₹1.64 lakh crore had been approved: one silicon fab, two compound-semiconductor fabs and nine packaging units. PIB, June 2026
Design Linked Incentive: As of March 2026, 24 companies had received fiscal support and 105 applicants had received access to design tools; seven chips had been fabricated from 16 tape-outs, including 12-nanometre designs.
Talent: The government reported that the target of training 85,000 semiconductor engineers was achieved in four years and set a target of training one lakh more.
Student design capability: Students from Tier-II and Tier-III cities had designed more than 250 chips by August 2026.
Global design presence: NITI Aayog estimates that India accounts for nearly one-fifth of the global semiconductor design workforce. NITI Aayog roadmap, 2026
International partnerships: Cooperation with major semiconductor economies can provide technology, equipment, capital, standards and supply-chain diversification, while contracts must incentivise domestic capability and knowledge diffusion.

Regulatory and Ethical Issues

Semiconductor policy must manage public-finance risk, technology dependence, environmental intensity, national-security concerns and the governance of dual-use capability.

High fiscal cost and opportunity cost: Large incentives may socialise investment risk; support should be milestone-based and linked to genuine capability, production, yield, skills and value addition.
Technology-transfer limits: Foreign investment can create capacity without transferring core process knowledge or intellectual property unless agreements and local ecosystems are designed accordingly.
Rapid obsolescence: Nodes, packaging architectures and equipment evolve quickly, creating a risk of subsidising assets that are technologically or commercially mismatched.
Supply-chain chokepoints: Advanced equipment, design software, wafers, gases and materials remain concentrated among a small number of countries and firms.
Water and energy footprint: Fabs need uninterrupted electricity and large volumes of ultrapure water; siting must account for basin stress, recycling and low-carbon power.
Environmental governance requirement
Project appraisal should disclose water sources, recycling rates, chemical handling, waste treatment and energy intensity. Industrial policy must avoid solving a technology-security problem by creating a local water or pollution crisis.
Cybersecurity and hardware trust: Malicious modification, counterfeit components and insecure supply chains can compromise critical infrastructure.
Export controls and geopolitical fragmentation: Rival technology blocs can restrict equipment, IP and markets; India must manage partnerships without excessive single-country dependence.
Workforce bottlenecks: Training targets do not automatically provide experienced process engineers, technicians, tool-maintenance specialists and research leaders.
Centre-state coordination: Land, power, water, local infrastructure and incentives are state-dependent, while strategic and fiscal policy is national.

Way Forward

India should pursue selective depth across the value chain, use public support to build learning and link every major project to measurable domestic capability.

Choose strategic segments: Prioritise mature nodes, compound semiconductors, power electronics, sensors, secure chips, advanced packaging and system-level design where demand and national strengths align.
Move from capacity to capability: Track yield, utilisation, domestic supplier development, patents, process know-how, exports and skilled employment rather than announcements alone.
Milestone-based incentive design
Disbursements should follow verified construction, tool installation, qualification, production and performance stages. Clawbacks and transparent reporting can protect public money when projects fail to deliver agreed outcomes.
Deepen design ownership: Expand access to EDA tools, prototyping, shared IP, patient capital, government procurement and deployment-linked incentives for Indian-controlled designs.
Build upstream suppliers: Support specialty chemicals, gases, substrates, components, clean-room equipment and maintenance services through standards and anchor demand.
Use advanced packaging as a leapfrog: Invest in chiplets, heterogeneous integration, high-bandwidth memory integration and thermal-management research.
Create research consortia: Connect universities, C-DAC, public laboratories, startups and firms around shared fabrication access and mission-oriented R&D.
Strengthen the talent pyramid: Combine university curricula with technicians, apprenticeships, fab internships, faculty development and global expert mobility.
Use trusted partnerships: Structure cooperation around co-development, supplier diversification, reciprocal market access and knowledge transfer.
Make fabs resource-responsible: Require high water recycling, renewable power, chemical traceability and public environmental reporting.
Develop trusted procurement: Strategic sectors should use secure design, traceable components, testing, certification and lifecycle support.
Plan for technology cycles: Periodically review the portfolio so public policy can shift from declining segments toward future value pools.
