Cleanroom fabrication facility

In 1987, India was two years behind the world's latest chip manufacturing technology. Today it is twelve generations behind.

A semiconductor cleanroom is the most demanding built environment humans construct. Fabrication requires Class 1 cleanrooms — air thousands of times purer than an operating theatre — uninterrupted high-voltage power, and large volumes of ultrapure water, all feeding tools that etch features measured in atoms. Only a handful of nations sustain this: the United States, Taiwan, South Korea, Japan and the Netherlands. In India, these capabilities are unevenly distributed, with only a handful of industrial zones approaching "fab-ready" standards.

The status as of 2026 is one of real, uneven ascent. On 28 February 2026, Micron's Sanand facility in Gujarat was inaugurated, its 500,000-square-foot Phase 1 cleanroom operational as part of a $2.75 billion investment — an assembly, test, marking and packaging (OSAT) plant, not a wafer fab. CG Semi launched an OSAT facility at Sanand in August 2025; Kaynes Semicon and Tata Electronics' TSAT plant in Morigaon, Assam are near first production. The Tata Electronics–Powerchip fab at Dholera, an ₹91,000 crore project targeting 2027 and 28-nanometre logic, remains in early engineering. DRDO's legacy units — GAETEC, STARC, SITAR and SCL Mohali — were built for strategic defence and ISRO use, never commercial scale.

The gap persists beneath the cleanroom walls. India imports over 90 percent of essential fabrication inputs: high-purity chemicals, specialty gases, silicon wafers and ultrapure water systems. It produces no commercial-grade wafers. Photolithography tools sit under an ASML–Canon–Nikon monopoly, with advanced systems export-controlled; plasma etch and deposition equipment is dominated by Applied Materials, Lam Research and Tokyo Electron. Every advanced fab under construction relies on foreign partnerships and technology. The cleanroom can be built in India; what happens inside it is largely imported.

Where India is genuinely building is the shell and its integration. Micron's Sanand cleanroom was constructed by TATA Projects using contemporary EPC methodology with 4D BIM and modular techniques. Indian specialists such as Pophen Technology India and Semicon Fab Technologies are integrating cleanroom systems into these projects. India is expected to record the highest CAGR in the global semiconductor cleanroom market from 2025 to 2030.

What it would take is visible in the dependency list. The India Semiconductor Mission offers 50 percent fiscal support for silicon CMOS fabs, but subsidy addresses capital, not capability. Closing the distance means indigenous wafers, gases, chemicals and process technology — the twelve generations — alongside the workforce the sector will need: over 100,000 trained cleanroom technicians and specialised engineers within five years.
