Intel backs Odisha chip substrate plant

Odisha has secured a proposed $3.3 billion semiconductor substrate project involving Intel Corporation and 3D Glass Solutions Inc., marking one of the largest high-technology manufacturing commitments tied to India’s chipmaking ambitions.

The memorandum of understanding, signed by the Government of Odisha, Intel and 3DGS, covers an advanced packaging glass-core substrate manufacturing facility in the Bhubaneswar-Khurda region. The project is expected to focus on substrates used in next-generation chip packaging, a part of the semiconductor supply chain that has gained strategic importance as artificial intelligence, high-performance computing and advanced data-centre processors demand larger, faster and more power-efficient packages.

The agreement places Odisha in a stronger position within India’s semiconductor map, which has so far been led by assembly, testing, marking and packaging projects, outsourced semiconductor assembly facilities, compound semiconductor proposals and early-stage fabrication investments. The planned plant would add a specialised layer to that ecosystem by targeting glass-core substrates and high-density interconnect technologies, areas that are increasingly viewed as critical for advanced packaging.

Intel’s role is expected to centre on technology know-how, process expertise and ecosystem support, while 3DGS brings specialisation in glass-based integration platforms. 3DGS, a US-based company, has developed glass-centric technologies for radio-frequency, photonics and semiconductor packaging applications. Its involvement gives the Odisha plan a sharper focus than conventional electronics manufacturing projects, as glass-core substrates remain an emerging technology rather than a mature commodity segment.

Glass substrates are attracting industry attention because conventional organic substrates face physical limits as chip packages become larger and denser. Advanced processors now often combine multiple chiplets, memory stacks and interconnect layers in one package. That increases pressure on the base material to carry more power and data connections while reducing warpage, signal loss and thermal stress. Glass offers better dimensional stability, finer interconnect potential and the ability to support larger package sizes, though yield, tooling and commercial-scale production remain challenges.

Intel has publicly positioned glass substrates as a key packaging technology for the second half of this decade. The company has argued that glass could help extend system-level performance gains beyond the limits of transistor scaling, particularly for artificial intelligence accelerators and high-performance computing chips. For India, participation in this segment could move the country beyond back-end assembly into a more advanced part of the global chip supply chain.

The Odisha project is also politically significant. The signing was witnessed by Union electronics and information technology minister Ashwini Vaishnaw and Odisha chief minister Mohan Charan Majhi, alongside senior executives from Intel and 3DGS. The state has been pushing to attract electronics, data centre and semiconductor-linked investments as part of a broader industrial strategy aimed at diversifying beyond metals, mining and ports.

The proposed facility is expected to be developed over several years, with industry estimates placing the build-out period at five to six years. Employment projections point to high-skilled roles across engineering, materials science, process control, quality systems and equipment maintenance, while indirect jobs could emerge through chemicals, gases, logistics, clean-room services and precision component suppliers.

The investment comes as India seeks to reduce dependence on overseas semiconductor supply chains after pandemic-era shortages exposed vulnerabilities in electronics, automotive and defence manufacturing. The Union government’s semiconductor programme has already backed projects by Tata Electronics, Micron Technology, CG Power and Kaynes, while several states are competing to attract design, packaging and manufacturing facilities. Gujarat and Assam have emerged as early beneficiaries, while Odisha’s Intel-3DGS agreement signals a broader geographic spread of the chip ecosystem.

For Intel, the deal fits into a wider effort to strengthen its foundry and advanced packaging credentials at a time when the global chip industry is being reshaped by artificial intelligence demand. The company has been investing in packaging platforms such as EMIB and Foveros, while also promoting glass substrates as a future enabling technology. Its broader turnaround remains under scrutiny because of competitive pressure from Nvidia, AMD, TSMC and Samsung, but advanced packaging offers a route to relevance in custom accelerators and multi-die systems.

The project will still have to pass execution tests before it becomes a production anchor. Semiconductor substrate manufacturing requires tight process control, specialised equipment, stable utilities, skilled technical labour and reliable supply of materials. Glass-core technology also needs commercial validation at scale, as the industry has not yet shifted from established organic substrate supply chains in volume applications.
