Semicon 2.0
One line
The Cabinet approved Semicon 2.0 with a stated outlay of ₹1,27,500 crore for semiconductor design, manufacturing, machines, materials, and packaging.
Summary
Semiconductors need a connected ecosystem. The six-pillar plan covers design, machines and materials, fabs, ATMP or OSAT, supply chains, and talent or research. The policy challenge is to build capacity that remains competitive after incentives end.
PYQ pattern
UPSC science and economy questions can test a technology through its supply chain. Use the official UPSC archive and revise wafers, lithography, fabs, packaging, and design IP.
Core notes
- A fab manufactures semiconductor devices on wafers. ATMP and OSAT involve assembly, testing, marking, and packaging.
- Semiconductor design creates intellectual property, layouts, and systems. Design capability is distinct from fabrication.
- Machines, chemicals, gases, water, power, clean rooms, logistics, and skilled workers are essential inputs.
- The release said the first fab was scheduled for commissioning in 2028. This is a stated schedule, not a completed outcome.
Prelims lens
- Design, fabrication, and packaging are different stages.
- ATMP means assembly, testing, marking, and packaging; OSAT means outsourced semiconductor assembly and test.
- A budget outlay is not the same as actual expenditure or production.

Mains
Question, 10 marks, 150 words: Why does semiconductor self-reliance require coordinated support for design, fabrication, packaging, skills, and supply chains?
Approach:
- Explain the semiconductor value chain.
- Discuss strategic electronics, economic value addition, jobs, and supply security.
- Examine capital intensity, technology cycles, water and power needs, talent, and export controls.
- Recommend stable incentives, common infrastructure, research links, trusted partners, and outcome-based support.
