India’s First Advanced 3D Chip Packaging Unit

Discover India’s first advanced 3D chip packaging unit—its cutting-edge semiconductor technology, role in boosting domestic chip manufacturing, and significance for strengthening India’s electronics ecosystem and supply chain resilience.

Context: Odisha is setting up India’s first advanced 3D chip packaging unit, marking a step toward high-end semiconductor manufacturing and global supply chain participation.

About the India’s First Advanced 3D Chip Packaging Unit Project

Implementation: The project is led by 3D Glass Solutions (US-based) through its Indian arm, also funded by Intel.
Under Government Mission: India Semiconductor Mission (ISM), which supports domestic chip manufacturing.
Technology: Uses 3D heterogeneous integration, meaning multiple chips are combined into one for better performance.

Ecosystem Significance

Complete Ecosystem: Odisha becomes the first state with both chip manufacturing (fab) and advanced packaging, strengthening the ecosystem.
Boost to ATMP/OSAT Sector: Improves India’s role in assembly, testing, marking and packaging, a key part of the chip supply chain.
Reduced Import Dependence: Less reliance on countries like Taiwan and South Korea for chip processing.

About 3D Chip Packaging

In 3D Chip Packaging, instead of placing chips side-by-side, chips are stacked one above another, which saves space and allows faster communication between them.

Key Components

3D Stacking: Multiple chips are placed in layers, so more components fit in less space.
Through-Silicon Vias (TSVs): These are tiny vertical connections that directly link stacked chips, allowing very fast data transfer.
Glass Substrate: Using glass as a base improves heat management, signal quality, and reduces energy loss, making chips more reliable.

Advantages

Higher Speed: Since chips are closer together, data travels shorter distances, resulting in faster processing.
Energy Efficient: Less distance and better design reduce power use, leading to lower energy consumption and less heat.
Compact Devices: Stacking chips is smaller and lighter without losing performance.
Advanced Applications: high-end uses like AI, 5G networks, defence systems, and supercomputing, where high speed and efficiency are essential.
