Tata Electronics and ASML Join Forces to Power India’s First 300mm Semiconductor Fab
Tata Electronics has taken a major step toward making India a serious player in global chip manufacturing by signing a memorandum of understanding with ASML. The partnership will support the setup and ramp-up of Tata Electronics’ upcoming 300mm semiconductor fabrication plant in Dholera, Gujarat.
The Dholera facility is one of India’s most ambitious semiconductor projects to date. Planned with an investment of around US$11 billion, it is expected to become the country’s first commercial-scale 300mm wafer fab. Once operational, the plant is set to produce chips for key sectors such as automotive, mobile devices, artificial intelligence, industrial electronics, connectivity, and power management.
ASML’s role is especially important because lithography is one of the most advanced and critical stages of semiconductor manufacturing. Lithography tools are used to print extremely fine circuit patterns onto silicon wafers, making them essential to chip production. Through this agreement, ASML will provide lithography systems and related support for the Dholera fab.
The collaboration goes beyond equipment supply. Tata Electronics and ASML also plan to work together on talent development, lithography skill-building, research and development infrastructure, and supply chain strengthening. These areas are vital for India as it works to move from semiconductor policy announcements to real manufacturing capability.
Tata Electronics is already working with Taiwan’s Powerchip Semiconductor Manufacturing Corporation, or PSMC, for technology support. That partnership gives Tata access to process technologies including 28nm, 40nm, 55nm, 90nm, and 110nm nodes.
While these are not the most advanced chip nodes used in cutting-edge processors, they are extremely important in the real-world semiconductor market. Mature and specialty nodes are widely used in automobiles, industrial systems, medical electronics, sensors, analog chips, telecom infrastructure, energy systems, mixed-signal components, and power management devices. Demand for these chips remains strong, especially as cars, factories, homes, and energy grids become more connected and intelligent.
The ASML agreement adds a crucial equipment and process layer to Tata Electronics’ semiconductor roadmap. Building a fab requires more than money and land. It needs highly specialized machinery, reliable utilities, process expertise, cleanroom operations, trained engineers, materials suppliers, maintenance capabilities, and strict quality control. ASML’s involvement can help Tata strengthen one of the most complex parts of that equation.
Dr. Randhir Thakur, CEO and managing director of Tata Electronics, said ASML’s lithography expertise will help support the timely ramp-up of the Dholera fab. He also emphasized that the partnership will help create a trusted semiconductor supply chain for global customers while supporting the development of local talent.
ASML CEO Christophe Fouquet said the company sees long-term opportunities in India’s growing semiconductor sector and expects to work closely with Tata Electronics and its wider ecosystem. The partnership also reflects broader cooperation between India and the Netherlands in critical technologies, including semiconductors.
India’s semiconductor industry has welcomed the announcement as a major milestone. Ashok Chandak, president of IESA and SEMI India, described the Tata-ASML partnership as a breakthrough moment in India’s semiconductor manufacturing journey.
For India, the agreement comes at an important time. Countries around the world are trying to diversify semiconductor supply chains after years of disruptions and rising geopolitical tension. India already has a strong chip design ecosystem, with many global semiconductor companies operating design and engineering centers in the country. However, India has historically lacked large-scale wafer fabrication capacity.
That is the gap Tata Electronics is trying to address with the Dholera fab. If successful, the project could help India move beyond chip design and assembly into full-scale semiconductor manufacturing. It could also attract suppliers, materials companies, equipment service providers, and skilled engineers to build a broader chip ecosystem around the fab.
However, industry experts caution that the real test will come during execution. A memorandum of understanding is an important signal, but a semiconductor fab becomes commercially meaningful only when it can produce chips reliably, at scale, and with strong yields.
Sanchit Vir Gogia, chief analyst and CEO at Greyhound Research, said the significance of the Tata-ASML partnership should be measured less by national symbolism and more by whether Tata can build a manufacturing system that global semiconductor customers trust.
According to Gogia, ASML helps reduce risk in the lithography layer, but it does not remove all the risks involved in building and running a fab. The harder challenge will be developing yield learning, supplier discipline, quality systems, and customer qualification processes fast enough.
He also warned against assuming that the Dholera facility is aimed at leading-edge EUV-based semiconductor manufacturing. A more realistic view is that ASML’s involvement will support a DUV-led mature-node and specialty chip manufacturing stack. That still matters greatly because mature-node semiconductors remain essential across automotive, industrial, telecom, healthcare, power, sensor, analog, and mixed-signal markets.
Tata’s wider semiconductor strategy is also beginning to take shape. PSMC is supporting process technology transfer, ASML is strengthening the lithography and equipment side, and Tata’s semiconductor assembly and testing project in Assam is expected to add downstream packaging and test capability. Together, these pieces could help India build a more complete semiconductor value chain.
Still, challenges remain. India needs deeper process-engineering talent, a stronger supplier base, semiconductor-grade chemicals and materials, experienced yield engineers, and equipment maintenance infrastructure. These capabilities take years to develop and require close coordination between industry, government, universities, and global technology partners.
Gogia suggested that a credible timeline for dependable commercial operations could be around FY2029-30, assuming construction, tool installation, process transfer, qualification, utilities readiness, and yield improvement stay broadly on track. As he noted, producing a wafer is not the same as running a dependable fab.
Even with those challenges, the Tata-ASML agreement is an important sign that India’s semiconductor ambitions are becoming more concrete. The Dholera fab is not just another industrial project. It represents India’s attempt to enter one of the world’s most strategic and technically demanding industries.
If Tata Electronics can execute successfully, the project could help India become a meaningful manufacturing hub for mature and specialty semiconductors, reduce dependence on overseas supply chains, and create a foundation for future growth in advanced electronics manufacturing.
