On 15 July 2026, the Union Cabinet approved Semicon 2.0 — the second, expanded phase of India's semiconductor push — with a total outlay of ₹1,27,500 crore. Building on Semicon 1.0 (the India Semiconductor Mission of 2021), it aims to develop India's chip design and manufacturing ecosystem across six pillars. For an NDA aspirant, semiconductors are among the most important science-and-technology topics today: chips power everything from smartphones to missiles, and India's drive for self-reliance in them is both an economic and a strategic story.
The news in one frame
The essentials:
- What: Cabinet approval of Semicon 2.0, outlay ₹1,27,500 crore.
- Builds on: Semicon 1.0 — the India Semiconductor Mission (ISM), approved December 2021 with ₹76,000 crore.
- Structure: a six-pillar approach spanning design, fabs, ATMP/OSAT, materials, equipment and talent.
- Goal: put India firmly on the global semiconductor map and reduce import dependence.
What is a semiconductor?
Start with the science. A semiconductor is a material whose electrical conductivity lies between a conductor (like copper) and an insulator (like glass) — and, crucially, can be controlled. The classic semiconductor is silicon. By adding tiny amounts of impurities — a process called doping — engineers create n-type (extra electrons) and p-type (extra "holes") regions; joining them makes the p-n junction, the basis of diodes and transistors. A modern microchip (integrated circuit) packs billions of transistors onto a fingernail-sized piece of silicon. Because chips are the "brain" of all electronics, they are called the "new oil" of the digital economy. This core physics is exactly what the NDA physics notes and general-science material build toward.
How a chip is actually made
NDA science questions increasingly test the manufacturing chain — three broad stages:
- Design: engineers design the circuit (India is already strong here — a large share of the world's chip designers are Indian). Semicon 2.0's first pillar builds on 100+ chip-design startups.
- Fabrication ("Fab"): the design is etched onto silicon wafers in ultra-clean fabrication plants using photolithography — the most capital-intensive step (a single fab can cost billions). Tata–PSMC's fab at Dholera, Gujarat is India's flagship.
- ATMP / OSAT: Assembly, Testing, Marking and Packaging (also called OSAT — Outsourced Semiconductor Assembly and Test) — where finished wafers are cut, packaged into chips and tested. Micron's plant at Sanand, Gujarat is an ATMP facility.
The mantra to remember: Design → Fab → ATMP/OSAT. India is entering all three stages, which is what makes the mission so significant. These applied-tech themes run through the NDA daily current affairs.
The India Semiconductor Mission and Semicon 2.0
Place the policy clearly:
- The India Semiconductor Mission (ISM) was approved in December 2021 with ₹76,000 crore, run under the Ministry of Electronics & IT (MeitY), offering up to 50% capital support for fabs and packaging units.
- Under ISM, projects were approved at Dholera and Sanand (Gujarat), Mohali, Assam (Jagiroad) and elsewhere — a mix of fabs and ATMP/OSAT units.
- Semicon 2.0 (₹1,27,500 crore) now expands this with a six-pillar framework covering chip design, manufacturing (fabs), assembly/packaging, materials & gases, capital equipment, and talent/R&D — a whole-ecosystem approach rather than just building plants.
The revision hook: semiconductor = controllable material (silicon), doped into p-n junctions; chip-making = Design → Fab → ATMP/OSAT; ISM (2021, ₹76,000 cr, under MeitY); Semicon 2.0 (2026, ₹1,27,500 cr, six pillars); flagship sites Dholera (fab) and Sanand (ATMP).
Why chips are strategic
For the bigger picture (and the SSB):
- Everything runs on chips: phones, cars, medical devices, satellites — and defence systems (missiles, radars, fighter avionics, drones). A country without chip capacity is strategically vulnerable.
- Supply-chain security: the world saw during the Covid-era chip shortage how dependence on a few countries (Taiwan, South Korea) can cripple industries; India wants resilience.
- Self-reliance: an indigenous chip ecosystem is core to Aatmanirbhar Bharat, Make in India, and Digital India — and reduces a huge import bill.
- Dual-use: the same fabs that make consumer chips can support defence electronics, tying semiconductors directly to national security.
Talent and the road ahead
Semicon 2.0's people-pillar matters for NDA aspirants specifically:
- India already supplies a large share of the world's VLSI/chip-design talent; the mission funds training, R&D and university tie-ups to build fabrication and packaging skills too.
- Related efforts include the C2S (Chips-to-Startup) programme and design-linked incentives.
- The aim is a complete pipeline — from students to startups to giant fabs — so India both designs and builds chips at home.
The "nanometre" and Moore's Law
One more concept the exam is starting to test — chip "nodes":
- A chip's generation is described by a nanometre (nm) figure (e.g., 28 nm, 7 nm, 3 nm) — historically the size of the smallest features on the chip. Smaller nm = more transistors, faster and more power-efficient chips.
- Moore's Law (Gordon Moore, 1965) observed that the number of transistors on a chip roughly doubles every ~2 years — the trend that made computing exponentially cheaper.
- India's fabs are starting with mature (larger-nm) nodes — the chips that run cars, appliances, power electronics and defence gear — which is a smart, high-demand entry point rather than chasing only the cutting edge.
So a lower nanometre number signals a more advanced chip, while mature nodes still power most of the real economy — a balanced takeaway for answers.
Exam relevance in one paragraph
For NDA General Science, retain: a semiconductor (like silicon) has conductivity between a conductor and insulator and is controlled by doping to form p-n junctions (the basis of transistors); a microchip packs billions of transistors; chip-making runs Design → Fab (photolithography on silicon wafers) → ATMP/OSAT (packaging & testing); the India Semiconductor Mission (2021, ₹76,000 cr, under MeitY) supports fabs at Dholera and ATMP at Sanand; Semicon 2.0 (2026, ₹1,27,500 cr) expands this across six pillars. For the SSB, semiconductors are a sharp example of technology as national security.

📋 How this gets asked (PYQ pattern)
Semiconductors are a fast-rising NDA science-and-tech set. The reliable framings are the physics (semiconductor, doping, p-n junction), the manufacturing chain (fab vs ATMP/OSAT), and the mission facts (ISM 2021, ₹76,000 cr, MeitY; sites Dholera/Sanand). A common trap puts the mission under ISRO or DRDO instead of MeitY, or confuses a fab with a packaging (ATMP) unit. The fresh 2026 hook is Semicon 2.0 and its ₹1,27,500 crore six-pillar plan — ideal for "which material / which step / which mission" items. We reference the pattern, not any exact past question.
