Why in News: On May 29, 2026, the Government of Odisha signed a tripartite MoU with US-based Intel and 3D Glass Solutions (3DGS) to bring advanced semiconductor substrate manufacturing to India — a key missing link in the country’s chip value chain. The pact complements 3DGS’s ~₹2,000 crore Heterogeneous Integration Packaging facility at Info Valley, Bhubaneswar (foundation laid April 2026), which will produce 70,000 glass panels and 13,000 3DHI modules annually. Union Minister Ashwini Vaishnaw (Electronics & IT) announced the deal.
The Substrate Gap — Why It Matters
A semiconductor substrate is the thin board (organic, ceramic, or increasingly glass) that:
- Holds multiple chip dies (System-in-Package, SiP) in a single package.
- Routes electrical signals between them.
- Provides mechanical support, heat dissipation, and external pin connections.
Substrates are the packaging layer — the last step before a chip ships to OEMs. Without domestic substrate capability, even Indian fabs would need to import substrates from Taiwan, South Korea, Japan or China.
| Substrate type | Current global leader | India presence (pre-MoU) |
|---|---|---|
| Organic (FR-4, BT, ABF) | Taiwan (Unimicron, Ibiden), South Korea (Daeduck) | Limited |
| Ceramic (LTCC, HTCC) | Japan (Murata, NGK) | Limited |
| Glass-core substrates | Emerging — Intel, Samsung, NHK Spring | Now coming via 3DGS-Odisha |
| Silicon interposers | TSMC (CoWoS), Samsung (I-Cube) | Nil |
Glass substrates are the next-generation packaging technology — they enable higher density interconnects (3D Heterogeneous Integration, or 3DHI), lower power loss, and better thermal performance than organic substrates.

Why This MoU Is Strategic
| Significance | Detail |
|---|---|
| Closes the back-end gap | India had no domestic substrate capability for advanced packaging |
| Glass substrates = next-gen | Intel itself is shifting to glass substrates for high-performance chips (announced September 2023) |
| 3DHI (3D Heterogeneous Integration) | Future packaging architecture for AI/ML, high-end mobile, automotive |
| Civil-military dual use | 3DGS supplies US DoD/DARPA — same tech can serve Indian defence applications |
| Odisha emerges as semi hub | First state hosting both compound semiconductor fab AND 3D glass substrate packaging unit |
| Counter to China supply concentration | Global packaging supply is heavily concentrated in Taiwan, China, South Korea — diversification value |
Odisha’s Semiconductor Push
| Initiative | Detail |
|---|---|
| Odisha Semiconductor Manufacturing & Fabless Policy 2023 | First state-level policy after Centre’s ISM |
| Info Valley, Bhubaneswar | Designated semiconductor hub; ~1,500 acres |
| Earlier announcement | RIR Power Electronics compound semiconductor fab (foundation 2024) |
| State CM | Mohan Charan Majhi (BJP-led govt since June 2024) |
| Skill ecosystem | IIT Bhubaneswar, IIIT Bhubaneswar, NIT Rourkela, multiple polytechnics |
Wider Significance
- Atmanirbhar Bharat for chips — back-end was the visible gap; this fills part of it.
- Strategic autonomy — packaging dependence on Taiwan was a critical chokepoint risk.
- Make-in-India for AI compute — glass substrates enable advanced AI packages; India can build GPU/AI-accelerator packaging domestically.
- State-level competition — Odisha joins Gujarat, Tamil Nadu, Karnataka, Telangana, Uttar Pradesh in active semiconductor incentivisation.
- India-US strategic tech partnership — under iCET (initiative on Critical and Emerging Technology) framework launched 2022; semiconductors are a flagship pillar.
Watchpoints
- Skilled workforce — packaging needs cleanroom technicians; current pipeline is thin.
- Materials chain — glass, photoresists, etch chemicals still largely imported.
- Geopolitical — Trump 2.0 US export-controls posture is still being defined; could affect tech transfer.
- State capacity — Odisha’s track record in tech is shorter than Tamil Nadu’s or Karnataka’s.
- IP and Trade Secrets — 3DGS’s PDG technology is patent-protected; freedom-to-operate is well-defined.
Way Forward
- Compound Semiconductor Mission — formalise as a separate mission under ISM 2.0.
- Skill mission — packaging-specific ITI / NSDC partnerships with Intel + 3DGS.
- Materials ecosystem — glass, photoresists, etch chemicals, abrasives — PLI for these as enablers.
- University R&D centres — IIT Bhubaneswar / IIT Madras / IIT Bombay packaging research labs.
- State coordination — common substrate-packaging skill pool across Odisha-Telangana-Karnataka.
