ASML’s 300 EUV Machines: India Supply Chain Entry Explored with Tata

For supply chain executives, the prospect of ASML outsourcing precision subassemblies to India represents a strategic shift from a highly concentrated European and U.S. supplier base—one that produces just 300 EUV machines annually—toward a distributed model that could mitigate geopolitical risks and align with India's aggressive localization push under ISM 2.0.

Early-stage discussions between Tata Electronics and ASML to manufacture components and subassemblies for extreme ultraviolet (EUV) lithography machines in India mark a potentially transformative development for the global semiconductor equipment supply chain. ASML, the Dutch company that holds a monopoly on EUV systems—producing only 300 of these advanced machines in 2025—is exploring a partnership that could introduce India as a new node in the tightly controlled, highly concentrated manufacturing ecosystem behind the world's most sophisticated chips. The talks, reported on August 1, 2026, are an extension of a May 16 memorandum of understanding focused on deploying ASML's advanced lithography tools at Tata Electronics' Dholera fabrication facility, and reflect a broader push under India's Semiconductor Mission 2.0 to localize high-value electronics manufacturing.

For ASML, whose market capitalization sits between $660 billion and $690 billion, the strategic rationale is multifaceted.

For ASML, whose market capitalization sits between $660 billion and $690 billion, the strategic rationale is multifaceted. Its EUV supply chain is currently anchored in Europe and the United States, with precision components sourced from a select group of specialized suppliers. Geopolitical tensions, trade restrictions, and the concentration risk inherent in such a setup have increased pressure to diversify. Integrating an Indian partner like Tata Electronics—India's largest semiconductor manufacturing entrant—offers a way to build resilience, potentially lower long-term costs through labor arbitrage, and align with the Indian government's ambitious incentives for local production. However, company representatives remain cautious: the discussions are preliminary, and sources emphasize that end-to-end machinery production in India is "a long time away." The immediate focus is on "manufacturing a part of it," such as subassemblies and precision-engineered modules.

From the Indian perspective, the move would represent a leapfrog moment. Manufacturing components for EUV machines requires extreme precision engineering, ultra-clean environments, and a deeply skilled workforce—capabilities that are still nascent in India. For Tata Electronics, which is already building a semiconductor fab in Dholera, the partnership could accelerate technology transfer and position it as a credible player in the global semiconductor equipment value chain. Under ISM 2.0, the government is explicitly targeting localization of subassemblies and support ecosystems, moving beyond chip packaging and testing into the tooling segment that has historically been dominated by a few developed economies. A successful collaboration could unlock ancillary industries in metrology, optics, and precision machining, creating a multiplier effect across India's electronics manufacturing sector.
