Summary of "विज्ञान एवं प्रौद्योगिकी (16-30 अप्रैल) | Sunil Sir | Springboard Academy"
Main ideas / Concepts Covered (Science & Technology; Exam-focused, 16–30 April)
1) India’s first “3D semiconductor packaging unit” in Bhubaneswar (Odisha)
- Location: Info Valley, Bhubaneswar (Odisha)
- Project type: Greenfield, stated as being set up for the first time in India
- Core innovation: glass-based substrate
- Traditional electronics use a thin plastic/semiconductor strip (green strip) to mount components.
- This project replaces it with a glass-based thin strip/substrate for component mounting.
- 3D packaging concept (multi-layering)
- Instead of placing one IC layer on the substrate, the design stacks ICs in a vertical/multi-storey manner (stacked “like multi-floor buildings”).
- Goal/benefits:
- smaller, lighter future devices
- better performance
- Who is involved
- American parent/company: 3D Glass Solutions Inc.

- Cost and funding (commonly asked)
- Total cost: ₹1943.53 crore (noted as slightly less than ₹2000 crore)
- Central Government: ₹799 crore
- State Government: ~₹399.5 crore
- Remaining: investment by the American company
