India ISM 2.0 Roadmap Targets 3nm and 2nm Advanced Node Chip Fabrication

ISM 2.0 Charts India's Path to 3nm and 2nm Advanced Node Semiconductor Fabrication

The India Semiconductor Mission 2.0 framework has outlined an ambitious multi-generational technology roadmap that targets domestic semiconductor fabrication at advanced nodes of 3nm and 2nm by the early 2030s. The announcement, made at SEMICON India 2026 in New Delhi, marks a significant escalation in India's semiconductor ambitions beyond the 28nm node that will be produced at the Tata Electronics Dholera facility when it delivers first wafers in December 2026. ISM 2.0 is backed by an additional government investment of Rs 40,000 crore, layered on top of the original ISM corpus, and is designed to fund the full technology progression from mature to leading-edge nodes over the next decade.

Why Advanced Nodes Matter for India

Advanced node fabrication at 3nm and 2nm is the frontier of semiconductor manufacturing, currently available only from TSMC in Taiwan, Samsung in South Korea, and Intel in the United States. These process nodes are required for the most compute-intensive chips including mobile application processors, AI accelerators, and high-performance computing dies. India's inability to manufacture at advanced nodes has meant that strategic sectors such as defence, telecommunications, and space have remained dependent on foreign fabrication for their most critical electronic components. ISM 2.0's commitment to a roadmap toward sub-5nm capability signals that India intends to close this gap over the course of the decade, rather than remaining permanently anchored at mature process geometries.

Stepping Stones: From 28nm to Advanced Nodes

The ISM 2.0 roadmap envisions a phased progression: first, establishing commercial 28nm production at Tata Electronics Dholera with initial capacity ramping through 2027 and 2028; second, adding a 12nm to 7nm process capability at a new facility under ISM 2.0 incentives, tentatively targeted for the early 2030s; and third, reaching 3nm to 2nm production through a joint venture with an advanced foundry partner, with government co-investment bridging the enormous capital gap that would otherwise make leading-edge investment unviable for Indian companies alone. Each step requires sustained investment in process technology, lithography equipment, process chemistry, and the specialised engineering talent to operate advanced fabrication environments.

EDA, Equipment, and Materials Ecosystem Development

Reaching advanced nodes requires not just a fabrication building but an entire surrounding ecosystem of electronic design automation tools optimised for target process design kits, precision metrology and inspection equipment, ultra-high purity process chemicals, and lithography systems that for nodes below 7nm require extreme ultraviolet technology exclusively supplied by ASML of the Netherlands. ISM 2.0 includes specific provisions for developing domestic capability in semiconductor materials, including silicon carbide for power devices, gallium nitride for RF and power applications, and high-purity silicon precursors. Incentive structures under ISM 2.0 are also expected to encourage global EDA vendors including Synopsys, Cadence, and Siemens EDA to establish deeper India research and development presences.

Strategic Rationale and Geopolitical Context

India's push toward advanced nodes is inseparable from the geopolitical context of global semiconductor supply chain restructuring. The concentration of leading-edge fabrication in Taiwan has become a systemic risk that major economies including the United States, European Union, Japan, and now India are actively working to diversify. India's large and growing domestic market for smartphones, data centres, EVs, and defence electronics creates a native demand base that can help justify the enormous fixed costs of advanced node fabs, which run into tens of billions of dollars. ISM 2.0's roadmap signals that India views semiconductor self-sufficiency not as an optional aspiration but as a national security and economic competitiveness imperative for the twenty-first century.
