India's first 3D glass chip-packaging unit breaks ground
Foundation stone laid at Info Valley, Bhubaneswar, for the country's first advanced 3D glass-substrate semiconductor packaging facility, cleared under the India Semiconductor Mission.
What happened
- The foundation stone for India's first advanced 3D semiconductor packaging unit was laid at Info Valley, in Khordha district near Bhubaneswar, Odisha.
- The project is the Heterogeneous Integration Packaging Solutions facility, promoted by the US firm 3D Glass Solutions Inc. (3DGS) through its wholly owned Indian subsidiary, Heterogeneous Integration Packaging Solutions Pvt. Ltd. (HIPSPL).
- It is a greenfield, vertically integrated ATMP unit built around embedded glass-substrate packaging — a back-end stage of chip-making, not a fabrication (front-end) plant.
- Total investment is ₹1,943.53 crore, supported by approved Central fiscal support of ₹799 crore and additional State support of roughly ₹399.5 crore.
- Planned annual capacity: about 70,000 glass panels, 50 million assembled units and ~13,000 advanced 3DHI modules.
- The ceremony was attended by Odisha Chief Minister Mohan Charan Majhi and the Union Minister for Railways, Electronics & IT, and Information & Broadcasting, Ashwini Vaishnaw.
- Commercial production is expected by August 2028, with full-scale volume production targeted by August 2030.
Background & context
Making a microchip runs through two broad halves. The front-end — fabrication, or the "fab" — etches transistors onto a silicon wafer in a process flow that can run hundreds of steps under extreme cleanliness. The back-end takes those finished wafers and turns them into usable devices: the wafer is diced, each die is assembled onto a substrate, the package is tested, marked and sealed. This back-end half is the work captured by the acronym ATMP — Assembly, Testing, Marking and Packaging (closely related to the term OSAT, Outsourced Semiconductor Assembly and Test). The Bhubaneswar facility is an ATMP/packaging unit, which is precisely why officials describe it as India's first advanced 3D packaging plant rather than a fab.
What makes this unit distinct is the substrate material. Conventional advanced packages route signals through an interposer or substrate made of silicon or organic laminate. This plant is built around an embedded glass substrate — glass panels into which interconnects and passive components are embedded. Glass offers a flat, dimensionally stable, low-loss platform that suits high-frequency and high-density routing, which is why such substrates are pitched for AI accelerators, high-performance computing and millimetre-wave 5G/6G parts. The output is described in 3DHI terms — 3D Heterogeneous Integration — where multiple dies (often from different process nodes, logic stacked with memory or analogue) are integrated vertically into one package rather than spread across a board.
The clearance sits under the India Semiconductor Mission (ISM), the nodal programme for building a domestic chip ecosystem. ISM operates as an independent business division within the Digital India Corporation under the Ministry of Electronics & Information Technology (MeitY), and administers the incentive umbrella commonly grouped as the Semicon India Programme, with a corpus that was announced at ₹76,000 crore. Its component schemes cover the whole chain: support for semiconductor fabs, display fabs, compound-semiconductor / silicon-photonics / sensor fabs and discrete units, the ATMP/OSAT scheme under which a packaging unit like this one qualifies, and the Design Linked Incentive (DLI) scheme for chip design. The mission is the policy vehicle behind the better-known approved projects — among them the Tata–PSMC fab in Dholera (Gujarat), the Tata (TSAT) and CG Power–Renesas and Micron and Kaynes packaging/assembly units in Gujarat — and now this glass-substrate unit in Odisha.
Odisha's position in this map is unusual. The release notes that it is the only State where both India's first compound-semiconductor fabrication unit and its first 3D glass-substrate packaging facility are being set up. Two semiconductor projects have already been approved for the State under ISM, with three more reported in the pipeline and discussions said to be underway with Intel. The State frames its own role through its IT, AI, GCC and Semiconductor Policies of 2025, which layer State-level capital support on top of the Central incentive — the ₹399.5 crore State component here is an example of that co-funding model.
It helps to place this unit within the wider set of semiconductor projects that India has approved, because UPSC questions on this theme often test whether an aspirant can sort fabs from packaging units and locate them by State. The fabrication (front-end) side includes the Tata Electronics–PSMC fab and the compound-semiconductor work concentrated largely in Gujarat. The packaging and assembly (back-end / ATMP) side includes Micron's assembly-and-test unit, the Tata (TSAT) packaging unit and the CG Power–Renesas–Stars unit, with Kaynes also in the assembly space — several of these clustered in Gujarat. Against that backdrop, the Odisha glass-substrate unit is notable on two counts: it is the first to use embedded glass substrates rather than silicon or organic ones, and it carries Odisha into a map that had been dominated by Gujarat. The point worth holding for revision is that packaging is the larger share of approved projects so far — India's near-term entry into chips is being led by the back-end as much as by marquee fabs.
The materials story behind the "glass" label is also worth a line. Advanced packaging has historically leaned on silicon interposers (precise but costly) and organic laminate substrates (cheaper but limited at high frequencies). Glass-core substrates sit between these: they are dimensionally stable, can be made in large rectangular panel formats rather than round wafers, and handle high-frequency signals with low loss — which is why they are being pursued for the densest AI and millimetre-wave packages. The "panel" capacity figure in the release (70,000 glass panels a year) reflects this panel-format processing, a different manufacturing geometry from the wafer-based flows of a fab.

Why it matters
India's semiconductor push has, so far, been weighted toward the high-visibility fabs. But a chip is not finished until it is packaged and tested, and global packaging capacity is geographically concentrated — a structural choke-point that a fab alone does not solve. Building advanced packaging capacity at home addresses that gap: it lets dies fabricated elsewhere (or in India's own future fabs) be assembled, integrated and tested domestically, deepening the value chain and reducing dependence on a small number of overseas packaging hubs.
The choice of glass-substrate and 3D heterogeneous integration is what places the unit at the leading edge rather than the commodity end of packaging. These are the package types being designed for AI accelerators, high-performance computing and millimetre-wave communications — the workloads where conventional substrates run into signal-loss and density limits. Locating that capability in India, with a named end-use list that explicitly includes defence electronics, automotive radar and aerospace, gives the country a foothold in packaging for strategically sensitive systems, not only consumer electronics.
The release also frames the broader trajectory: electronics-manufacturing production is stated to have grown roughly six-fold over twelve years, with India described as the world's second-largest mobile-phone manufacturer and a leading exporter of mobile phones in 2025. The semiconductor build-out is the next layer of that story — moving from assembling finished electronics toward making and packaging the chips inside them. For Odisha specifically, anchoring two firsts (a compound-semiconductor fab and a glass-substrate packaging unit) seeds a regional cluster, with the supplier base, skilled workforce and ancillary investment that tends to follow an anchor plant.
