India’s first 3D semiconductor packaging unit signals a deeper shift in the chip supply chain

Why Odisha’s new glass-based advanced packaging facility is less about manufacturing scale, and more about IP, ecosystem control, and long-term enterprise relevance.

India’s semiconductor push has taken a step forward with the groundbreaking of its first advanced 3D chip packaging facility in Odisha. The significance of the project lies less in investment size or capacity and more in the technology layer it targets.

The facility focuses on capability, intellectual property, and ecosystem positioning, indicating a shift from assembly-led manufacturing to deeper participation in the global semiconductor value chain.

The Odisha plant is being set up by US-based 3D Glass Solutions (3DGS) through its Indian subsidiary, Heterogeneous Integration Packaging Solutions.

It will focus on advanced 3D heterogeneous integration using glass substrates. This is an emerging packaging approach used in AI, high-performance computing, defence electronics, and next-generation telecom systems.

Unlike conventional assembly, testing, marking, and packaging (ATMP) units that rely on imported substrates and standardised processes, the facility targets a more IP-intensive segment of semiconductor manufacturing. This positions it differently within the supply chain.

The IP and technology moat

At the core of the project is 3DGS’s APEX glass-ceramic packaging platform. The platform is supported by over 100 patents across 31 active patent families globally. These patents cover materials engineering, manufacturing processes, device architectures, and system-level integration.

These are areas where India has had limited presence so far.

The Odisha facility will initially support both internally manufactured glass substrates and externally sourced organic substrates. This allows early commercial operations while the ecosystem develops locally.

Over time, the roadmap is to transition fully to glass-based advanced packaging. Glass substrates offer better thermal management, higher interconnect density, and improved reliability.

These capabilities are important for AI accelerators, advanced computing systems, and defence-grade hardware.

If executed as planned, this creates an upstream shift in sourcing. Indian system integrators, OEMs, and government suppliers could source advanced packaged components domestically instead of depending entirely on packaging hubs in Taiwan and South Korea.

For sectors including data centres, telecom infrastructure, aerospace, and defence electronics, this improves supply resilience and provides more control over a critical layer of the hardware stack.

Why the India Inc. connection matters

Project execution involves Indian engineering partners, including Tata Consulting Engineers, according to people familiar with the project, with work spanning early-stage engineering and planning. The engagement reflects increasing domestic capability in designing and executing semiconductor-grade facilities.

At the same time, discussions are ongoing with global equipment vendors for panel-level processing tools.

This indicates a move beyond policy support towards execution in semiconductor manufacturing.

Globally, 3DGS is backed by investors, including Intel Capital, Lockheed Martin Ventures, Applied Ventures, and Walden Catalyst Ventures. Their presence reflects the strategic importance of underlying technology.

The combination of global IP, Indian execution capability, and public sector support suggests a more mature semiconductor approach. India is not positioned only as a low-cost manufacturing base but is targeting higher-value segments of the supply chain.

For the channel ecosystem, the impact extends beyond chip manufacturing.

Odisha is beginning to develop early cluster effects. More than ₹10,000 crore has already been committed across semiconductor and electronics manufacturing projects in the region.

Companies such as RIR Power Electronics and SiCSem are part of this ecosystem.

This creates downstream opportunities in areas including data centre infrastructure, semiconductor testing and inspection, speciality materials, cybersecurity services, and managed IT operations.

These opportunities are likely to expand, particularly across eastern India.

A capability-led semiconductor shift

The importance of the Odisha facility lies in the layer of the value chain it addresses. Advanced packaging, especially heterogeneous integration using glass substrates, is becoming a key area for performance improvements as transistor scaling slows.

By building this capability domestically, India is positioning itself closer to where differentiation and value capture take place in the semiconductor ecosystem.

For the channel community, this marks a shift in opportunity. As advanced semiconductor capabilities develop locally, demand will extend beyond manufacturing.

System integrators, managed service providers, defence IT vendors, data centre operators, and infrastructure partners will all be part of the downstream ecosystem linked to these capabilities.

The Odisha facility signals how India’s semiconductor strategy is beginning to translate into enterprise-level opportunities and a broader ecosystem build-out.
