 Macro Strategic Imperatives & India’s Chip Landscape

  1. Foundational Economic Driver- Semiconductors are the core building blocks of modern electronics, AI, telecommunications (5G/6G), defense systems, electric vehicles (EVs), and hyperscale data centres.
  2. Global Market Trajectory- The global chip market expanded at 6.5% CAGR (2014–2024) and is projected to accelerate at 8.5% over the next decade toward a $1 trillion+ industry.
  3. Severe Import Dependency- India currently imports 90% to 95% of its semiconductor consumption, having spent USD 150 billion on chip imports between FY17 and FY25 (surging at a 23% CAGR).
  4. Demand Projections & Forex Risks- Domestic semiconductor demand is set to touch USD 110 billion by FY2030 and exceed USD 200 billion by FY2035; unchecked reliance could drive annual imports to USD 240 billion by 2035.
  5. Geopolitical Chokepoint Exposure- Over 60% of global foundry capacity and  90% of advanced sub-7nm logic nodes are concentrated in Taiwan, exposing downstream industries to geopolitical flashpoints and supply disruptions.
  6. Critical Defense & Strategic Reliance- Sovereign indigenous chip production is non-negotiable for defense avionics, UAVs, naval combat management, and missiles to eliminate foreign backdoors and supply embargoes.

Physics, Nodes & Fabrication- From Sand to Packaged Chip

  1. Physics of Controlled Conductivity- Unlike pure conductors or insulators, semiconductors (chiefly silicon) can be chemically modulated via doping to switch, amplify, sense, or route currents via microscopic transistors.
  2. The Fabrication Pipeline-

a.     Silica Sand Electronic-Grade Polysilicon (melted into single-crystal cylindrical ingots).

b.     Ingot Slicing & Polishing (yielding ultra-flat bare silicon wafers).

c.     Front-End Processing (40–50 printed layers deposited, etched, and patterned via photolithography and ion implantation).

d.     Wafer Dicing (separating individual integrated circuits/dies).

e.     Back-End Assembly & Packaging (ATMP/OSAT- encasing dies, wire-bonding/bumps, quality verification, and testing).

  1. Understanding Semiconductor Nodes- A node denotes a technology generation; smaller nodes (e.g., 14nm, 7nm, 3nm) pack exponentially more transistors per unit area, reducing power draw while boosting compute performance.
  2. Advanced vs. Mature Nodes- Advanced nodes (<7nm) power high-performance computing (HPC) and smartphone SoCs; mature/legacy nodes (28nm to 90nm+) remain indispensable for automobiles, smart grids, power electronics, and aerospace.
  3. Back-End Packing (ATMP/OSAT)- Assembly, Testing, Marking, and Packaging bridges raw silicon dies to printed circuit boards (PCBs), providing physical protection and heat dissipation.

Policy Architecture- Semicon 1.0 to Semicon 2.0 (The Six Pillars)

  1. Semicon 1.0 Delivery- Approved in December 2021 with ₹76,000 crore, establishing 50% fiscal parity across fabs and packaging. By mid-2026, 12 manufacturing units were approved (>₹1.64 lakh crore investment) across 6 states, with 5 units already entering commercial production.
  2. Diversified Unit Mix- Encompasses 1 silicon fab, 1 silicon carbide (SiC) fab, 1 Gallium Nitride (GaN) Micro-LED display fab, and 9 ATMP/OSAT packaging plants across Gujarat, Assam, UP, Odisha, Punjab, and Andhra Pradesh.
  3. Semicon 2.0 Escalation- Approved on July 15, 2026, with an enhanced outlay of ₹1,27,500 crore, expanding focus beyond fabs to upstream chemicals, equipment, materials, and long-term domestic IP creation.
  4. Upstream Supply Chain Localization- Incentivizes local production of specialty electronic chemicals, ultra-pure gases, silicon carbide/sapphire substrates, and manufacturing tools under the Machines & Materials pillar.
  5. Design-Linked Incentives (DLI)- Approved 24 chip design projects (valued at ~₹900 crore), supporting domestic fabless startups with design infrastructure and commercialization incentives.

Indigenous Capabilities, Strategic Missions & Talent Infrastructure

  1. Heritage at SCL Mohali- The Semiconductor Laboratory (SCL) under MeitY designs and produces flight-grade, radiation-hardened microelectronics for space and defense applications.
  2. Space Heritage Milestones-
    1. SCL’s Vikram 1601 processor powers navigation and guidance computers on ISRO launch vehicles.
    2. Custom Indian-made camera sensor chips supported the Chandrayaan-3 lander imaging system.
    3. Radiation-hardened Analog-to-Digital Converter (ADC) chips designed by SCL are deployed on the Aditya-L1 solar observatory. 
  1. Democratizing Design via ChipIN Centre- The centralized C-DAC ChipIN Centre provides cloud access to EDA design tools for >1 lakh engineers across 500+ entities (400 universities, 100 startups), resulting in >300 custom chip designs.
  2. Chips to Startup (C2S) Programme- Deployed industrial EDA software suites across 320 academic institutes, actively training over 68,000 students to build a domestic workforce pipeline of 85,000 semiconductor engineers this decade.
  3. Global Talent Concentration- India currently hosts 7% of global Semiconductor Global Capability Centres (GCCs) and accounts for nearly 20% of the world's chip design engineering talent.

Geopolitics, Multilateral Partnerships & Supporting Policy Ecosystem

  1. The Pax Silica Coalition- India joined the multinational Pax Silica alliance at the India AI Impact Summit (February 2026), working with democratic partners to secure the full "silicon stack" from critical minerals to AI compute.
  2. Bilateral Semiconductor Accords- Operationalized bilateral technology corridors with the United States, Japan, the European Union, Singapore, the Netherlands, and signed the India-Germany Semiconductor Ecosystem Partnership (January 2026).
  3. Complementary Domestic Policy Stack-

a.     NPE 2019 & SPECS- Anchors capital subsidies for electronic sub-assemblies and component supply chains.

b.     PLI 2.0 for IT Hardware & Electronics- Boosts domestic assembly of servers, PCs, laptops, and networking hardware to generate local chip demand.

c.     Electronics Components Manufacturing Scheme (ECMS)- Budget allocation expanded to ₹40,000 crore (FY 2026–27) to accelerate domestic component integration.

d.     100% Automatic FDI Route- Attracts global foundry giants and joint ventures into greenfield manufacturing corridors.

  1. Environmental & Resource Infrastructure- Fabs require massive infrastructure including uninterrupted green electricity corridors, millions of liters of Ultra-Pure Water (UPW), and hazardous chemical waste treatment facilities.
  2. Societal & Strategic Dividends- Localized fabrication secures domestic telecommunications networks, supports affordable 5G/6G rollouts, curbs forex outflows, and anchors India's digital sovereignty on the path to Viksit Bharat@2047.
