India Wires Up Its Nano-Fabrication Base, From Cleanrooms to Startups

On 22 May 2026, the Indian Institute of Science (IISc) inaugurated the Wadhwani-IISc Innovation Centre, a facility built to translate deep-tech research, MEMS components and solid-state and quantum sensing among them, into startups, and wired directly into IISc's nano-fabrication infrastructure. On its own it is one launch among many. Read alongside two other developments, a ₹720 crore commitment to quantum-chip fabs and a new sensors-and-MEMS track in the country's semiconductor mission, it marks something larger: India is deliberately building out the unglamorous middle of the nanotechnology stack, the fabrication base, and the route from cleanroom to company.

The shared-cleanroom model

Nano-fabrication is brutally capital-intensive. Patterning structures measured in nanometres requires cleanrooms, lithography tools and metrology equipment that no single laboratory, and certainly no startup, can afford alone. A single advanced lithography tool can cost more than an entire research grant. India's answer has been the shared national user facility: build the cleanroom once, with public money, and open it to everyone who needs it.

The anchor is CeNSE at IISc, whose National Nanofabrication Centre has run a roughly 14,000-square-foot cleanroom capable of CMOS, MEMS and NEMS work since 2010. Layered on top is INUP-i2i, the Indian Nanoelectronics Users Programme, which since 2021 has opened nanofabrication centres at IISc and at the IITs in Bombay, Delhi, Madras, Kharagpur and Guwahati to outside researchers and entrepreneurs. IIT Madras runs its own Centre for NEMS and Nanophotonics, and the Tamil Nadu government has seeded a Centre for Advanced Semiconductor Technologies there. The point of all of it is access: a small team can design a micro-electromechanical sensor or a nanophotonic device and actually build a working prototype without owning a fab.

That open-access model is genuinely powerful, but it has historically had a gap at the end. A researcher could prototype a device and publish a paper, and then the trail went cold, because there was no obvious path from a successful cleanroom run to a company that could make the thing at volume.

The commercialization layer

That is the gap the Wadhwani-IISc centre is built to close. Alongside the research infrastructure it adds cleanroom prototyping lines aimed at startups, an accelerator branded "InQubate," and access to capital, so that a MEMS or quantum-sensing idea has somewhere to go after the paper is published. It sits within the Wadhwani Innovation Network, a national pool of deep-tech funding assembled by the Wadhwani Foundation with the Anusandhan National Research Foundation, and it is plugged into IISc's existing quantum and fabless-component initiatives. The intent is explicit: turn the shared cleanroom from a research facility into the front end of a manufacturing pipeline.

New money behind the fabs

The infrastructure is also being topped up with serious capital. In late November 2025, the government committed ₹720 crore to build four nano-fabrication facilities for quantum-computing chips and quantum sensors, spread across IIT Bombay, IISc, IIT Delhi and IIT Kanpur under the National Quantum Mission, covering superconducting and photonic qubit-chip fabrication and quantum metrology. And the Union Budget for 2026-27 launched India Semiconductor Mission 2.0 with, for the first time, a scheme that explicitly funds sensors and MEMS fabs at 50% of capital cost, a category of device that India today imports almost entirely despite using it in everything from cars to phones to industrial equipment.

It is worth being precise about what this is and is not, because the history here is muddled. The older DST Nano Mission has not been revived with a fresh budget; the dedicated fabrication money has instead migrated into the quantum and semiconductor missions, which is where it now flows. Per-facility cleanroom specifications for the new quantum fabs have not been disclosed, so the headline figure is a commitment rather than a detailed plan.

Why fabrication is the constraint

The through-line of all three developments is a recognition of where India's real bottleneck in nanotechnology lies. The country produces a great deal of nano-scale research, measured in papers and citations, it is genuinely strong. What it has lacked is the capacity to make devices at quality and consistency, and the path to turn a working prototype into a business. Pouring money into shared fabs, opening them to startups, adding a commercialization layer, and earmarking capex specifically for sensors and MEMS attacks exactly that constraint, the conversion of knowledge into manufactured product.

The honest caveat is that cleanroom capacity is not the same as competitive manufacturing. MEMS, quantum-sensor and qubit-chip production is yield-sensitive and slow to mature, the equipment supply chain is itself largely imported, and standing up a fab is only the first step toward making devices anyone wants to buy. The right measure of success will not be crore committed or cleanrooms inaugurated, but qualified devices shipped and startups that survive past their prototypes. On that measure the verdict is years away, but the strategy, build the fabrication base, open it, and fund the path to market, is aimed at the correct problem.
