India's Semiconductor Mission 2.0 — From Broken Dreams to a ₹1.27 Lakh Crore Bet

UPSC Mains 2025, GS-3 (15 marks): “India aims to become a semiconductor manufacturing hub. What are the challenges faced by the semiconductor industry in India? Mention the salient features of the India Semiconductor Mission.”

As direct as it gets — asked when ISM 1.0 was current. With Semicon 2.0 approved (15 July 2026), expect an updated version in 2026 Mains.

• 2025 GS-3: challenges when the world moves from free trade to protectionism — the global chip war IS protectionist industrial policy (CHIPS Act, EU Chips Act, ISM).
• 2020 GS-3: industrial corridors (DMIC) — fabs need dedicated “chip corridors” (Dholera, Sanand).
• 2014 GS-3: declining university research — the talent gap (250,000–350,000 chip engineers by 2027).
• 2019 GS-3: S&T contributing to the national economy — ISM is the biggest such measure in Indian history.
• Prelims 2022: a statement-based factual question on chip-making (silicon wafers, photolithography).

• 1. Challenges + government response — list the constraints, show how ISM addresses each (the 2025 question).
• 2. Strategic self-reliance and national security — chips power missiles, satellites, jets; import dependence = borrowed defence capability.
• 3. Industrial policy and state capacity — can the state execute a ₹1.27 lakh crore programme? (Micron success vs Vedanta-Foxconn collapse.)
• 4. Global geopolitics of technology — US-China chip war, Taiwan risk, ASML monopoly, export controls.

Trend alert: the 2025 direct question plus the 15 July 2026 approval make a 2026 Mains question a near-certainty — either directly on Semicon 2.0 or linking chips to geopolitics, supply-chain resilience, or industrial policy.

• Step 1 — Design: engineers design the circuit in software. India is very strong here — Intel, Qualcomm, AMD run large design centres in Bengaluru and Hyderabad.
• Step 2 — Fabrication (the “fab”): the design is printed onto a silicon wafer with ultraviolet light and chemicals, layer by layer, in a dust-free clean room. The machines cost hundreds of millions each — ASML’s EUV lithography system runs ~$200 million, and only ASML (Netherlands) makes it. This is India’s big gap.
• Step 3 — Assembly, Test, Marking, Packaging (ATMP/OSAT): wafers are cut into chips, tested and packaged. Less complex than fabrication; India is building capability here.
• Step 4 — Integration: packaged chips go into devices, vehicles, weapons and medical equipment.

The global chip industry is ~$600 billion, but the electronics it powers exceed $3 trillion — every ₹1 on chips enables ₹5–6 of value downstream. That is why governments treat semiconductors as a “foundational” industry. Know the difference between design, fabrication and packaging — it separates you from 90% of candidates.

In 1976 the Cabinet under Indira Gandhi approved a bold plan: India would build its own semiconductor complex. The field was wide open — Taiwan had not entered chips, China was nowhere, South Korea was just starting. A 100% government-owned Semiconductor Complex Limited (SCL) was set up in Mohali, and began production in 1984 at 5-micron (5000 nm) CMOS, soon upgrading to 800 nm — barely a year or two behind Intel. TSMC, which today makes ~90% of the world’s advanced chips, was not even founded until 1987 — India had a head start.

Then on 7 February 1989 a mysterious fire (starting at multiple points) gutted the line, destroying imported equipment worth ₹60 crore. The IB probe was inconclusive; sabotage was suspected but never proven. The real damage came after: the government simply did not rebuild. Partial operations resumed only in 1997 — eight years later — and only because ISRO stepped in. By then the world had moved generations ahead. In 1987 India was two years behind the frontier; today it is roughly 12 generations behind.

The history is full of “almosts”: 1964 Fairchild’s Robert Noyce explored a plant — refused by the licence-permit raj; he went to Hong Kong and later co-founded Intel. 2005–06 Intel explored again — bureaucratic hurdles won. 2007 HSMC (Gujarat) and Fab City (Hyderabad) both failed for want of investor confidence. 2013 the $19.5 billion Vedanta-Foxconn fab collapsed. Instead, India became the world’s back-office — brilliant at writing code, unable to make the hardware that runs it. By 2020 India imported chips worth over $30 billion a year.

When supply chains collapsed in 2020, car makers, phone makers and medical-equipment firms ran short for two years. The lesson for India was brutal: we design some of the world’s best chips (for Intel, Qualcomm, NVIDIA, AMD, Broadcom) but cannot make a single one on our soil — we depend entirely on Taiwan, South Korea and the US. That moment led to the India Semiconductor Mission.
