Q. What structural bottlenecks impede India from emerging as a global semiconductor manufacturing hub? Suggest a roadmap to overcome them. (15 marks, 250-350 words)

Semiconductors are the foundational input for electronics, defence, automotive and AI systems, yet India still has no operational fabrication unit, with commercial output from the Dholera fab expected only towards the end of the decade. NITI Aayog's Future of India's Semiconductor Industry roadmap (May 2026) targets a USD 120–150 billion domestic value chain by 2035 [1] — a goal blocked by deep structural constraints.

Structural bottlenecks - Missing fabrication base: approved units are still under construction; ATMP/OSAT facilities such as Micron's Sanand plant and Tata's Jagiroad (Assam) unit [4] are downstream packaging, not chip fabrication. - Technology and input dependence: India's entry is at mature nodes, while advanced logic remains concentrated in Taiwan and South Korea; EUV lithography, specialty chemicals, gases and ultra-pure water systems are import-dependent [1]. - Capital intensity: fabs demand multi-billion-dollar, long-gestation, cyclical investment, requiring fiscal support of up to 50% of project cost [3] — patient private capital remains scarce. - Talent mismatch: India's strength lies in fabless design (VLSI); process, equipment and materials engineers for fab operations are in short supply [1]. - Infrastructure and coordination: 24×7 quality power, ultra-pure water and vibration-free sites need sustained MeitY–State convergence.

Roadmap ahead - Pursue the "More-than-Moore" strategy — dominance in mature logic nodes, advanced packaging and compound semiconductors (SiC/GaN) rather than chasing the 3nm frontier [1]. - Implement ISM 2.0, focused on domestic semiconductor equipment and materials, full-stack Indian IP, and supply-chain resilience [2]. - Build talent through subsidised industry-grade design tools for academia and fab-specific skilling under the roadmap's People pillar [1]. - Anchor demand via defence, automotive and telecom procurement, and deepen partnerships (iCET, Japan) to ride the China+1 shift. - Replicate Dholera-style plug-and-play clusters with State-level incentives, as in Gujarat and Assam [4].

India's chip journey is thus a marathon of ecosystem-building, not a sprint to a single fab. Sequenced execution — packaging first, fabs next, equipment and IP thereafter — can convert strategic necessity into commercial strength, advancing Aatmanirbhar Bharat and secure global supply chains.
