Two additional semiconductor manufacturing units
One line
The Cabinet approved two semiconductor manufacturing units with cumulative proposed investment above ₹3,900 crore.
Summary
Semiconductors are foundational inputs for communications, vehicles, defence, energy systems, and consumer electronics. Domestic production can improve resilience, but it also needs design capability, equipment, materials, skills, water, power, and global market links.
PYQ pattern
UPSC can connect chip policy with strategic autonomy, global value chains, industrial incentives, and skilled employment.
Core notes
- Semiconductor policy supports different layers, including fabrication, packaging, testing, design, equipment, and materials.
- Public incentives address high capital cost and ecosystem coordination failures.
- Manufacturing resilience does not require every input to be produced domestically.
- Project evaluation should examine technology, utilisation, value addition, and spillovers.
Prelims lens
- A semiconductor's electrical conductivity lies between that of a conductor and an insulator.
- Assembly, testing, marking, and packaging are different from wafer fabrication.
- Chips are manufactured through repeated deposition, lithography, etching, and doping steps.
