Robotics, semiconductors & quantum technology

Why Semiconductors Are a National-Security Question

Semiconductors—integrated circuits etched onto silicon wafers—are the substrate of modern computing, defence avionics, telecom, automobiles and AI accelerators. India consumes a large and rising share of global chips but, until recently, fabricated none of the advanced logic itself. The COVID-19 supply shock (2020-22) and the US-China technology rivalry converted chips from a commercial input into a sovereignty issue.

The Semicon India Programme

The Union Cabinet approved the Semicon India Programme in December 2021 with an outlay of ₹76,000 crore, administered through the India Semiconductor Mission (ISM), a body under the Ministry of Electronics and Information Technology (MeitY). The scheme offers fiscal support of up to 50% of project cost for setting up semiconductor fabs, display fabs, compound-semiconductor and ATMP/OSAT (assembly, testing, marking and packaging) units, and a Design Linked Incentive (DLI) scheme for chip-design start-ups.

The flagship outcomes:

• Micron Technology (US) committed in June 2023 to an ATMP facility at Sanand, Gujarat, with investment up to $2.75 billion, India's first major packaging plant.
• The Union Cabinet in February 2024 cleared three units: a Tata Electronics–Powerchip (PSMC, Taiwan) fab at Dholera, Gujarat (~₹91,000 crore), a Tata ATMP unit at Jagiroad, Assam, and a CG Power–Renesas–Stars Microelectronics OSAT unit at Sanand.
• Kaynes Semicon and others followed, building an OSAT ecosystem.

The Geopolitics and the Materials Layer

Global chipmaking is concentrated: TSMC (Taiwan) dominates leading-edge logic, ASML (Netherlands) monopolises EUV lithography, and Samsung/SK Hynix (South Korea) lead memory. The US CHIPS and Science Act (2022) and export controls on advanced nodes to China have fragmented supply chains—creating India's opening as a "China-plus-one" base. India joined the US-led Indo-Pacific Economic Framework (IPEF) supply-chain pillar and signed an MoU on semiconductor supply chains with the United States in March 2023.

Candidates must grasp the upstream dependency: chip fabrication needs ultra-pure silicon wafers, photoresists, neon gas, gallium and germanium. China restricted gallium and germanium exports in August 2023, underscoring the criticality of materials—linking this topic directly to the critical minerals and rare-earth debates examiners favour. India's response includes the Critical Minerals Mission (Budget 2024-25) and the Khanij Bidesh India (KABIL) acquisitions abroad.

The high-yield retention list: Semicon India outlay ₹76,000 crore; ISM under MeitY; Micron–Sanand; Tata–PSMC–Dholera; 50% fiscal support; DLI for design start-ups.

The National Quantum Mission

Quantum technology exploits superposition and entanglement to deliver computing, communication, sensing and materials capabilities that classical systems cannot match. India's centrepiece is the National Quantum Mission (NQM), approved by the Union Cabinet in April 2023 with an outlay of ₹6,003.65 crore (2023-31) under the Department of Science and Technology (DST).

The NQM sets four time-bound technical verticals and creates four Thematic Hubs (T-Hubs) across institutions:

• Quantum Computing: build intermediate-scale quantum computers of 20-50, then 50-100, then 50-1000 physical qubits on platforms including superconducting and photonic systems.
• Quantum Communication: satellite-based secure quantum key distribution (QKD) over 2,000 km within India, and inter-city QKD.
• Quantum Sensing & Metrology and Quantum Materials & Devices.

Globally, quantum computing threatens current public-key cryptography (RSA, ECC) via Shor's algorithm, driving the race for post-quantum cryptography—the US NIST standardised the first PQC algorithms (ML-KEM, ML-DSA) in August 2024. This makes quantum a cybersecurity and national-security subject, not merely a physics curiosity.

Robotics, Automation and the AI Convergence

Robotics is converging with artificial intelligence into autonomous systems with sharp strategic and economic stakes. In defence, DRDO programmes include the DRDO Daksh remote-operated vehicle for IED disposal and the MUNTRA unmanned tank, while loitering munitions and autonomous drones featured in recent conflicts (Nagorno-Karabakh 2020, Ukraine 2022-). India's drone policy framework rests on the Drone Rules, 2021 and the PLI scheme for drones and drone components (2021).

On the economic side, India ranks among the world's faster-growing markets for industrial robots (International Federation of Robotics data), concentrated in automotive and electronics manufacturing—reinforcing the Make in India and PLI push. Surgical robotics, agricultural automation and warehouse robots are expanding civilian frontiers.

The policy tension examiners probe: automation's effect on India's demographic dividend and jobs. The counter-argument—articulated in successive Economic Surveys—is that skilling (the Skill India Mission, Future Skills PRIME for IT) and higher-value manufacturing can absorb displacement.

Why This Matters For The Exam

This cluster is squarely a GS Paper III topic: "developments in science and technology and their applications" and "awareness in the fields of IT, space, computers, robotics... indigenisation of technology." In Prelims, expect factual MCQs—match the mission to its ministry (NQM→DST; Semicon India→MeitY), the outlay, the qubit targets, and which firm built which fab. In Mains, the question is analytical: "Examine India's strategy to build sovereign semiconductor and quantum capability and the dependencies it must overcome." PYQ patterns reward candidates who connect the technology to strategic autonomy, supply-chain security, critical minerals and cybersecurity rather than reciting brochure facts. Always quote the scheme name, year, ministry and outlay—precision is what distinguishes a top script.
