Enhanced Key Takeaways
- •The Dholera facility, a joint venture between Tata Electronics and Taiwan's Powerchip Semiconductor Manufacturing Corp (PSMC), is designed to produce 50,000 wafers per month at full capacity.
- •While the initial phase focuses on 90nm nodes, the facility is strategically designed to support future upgrades to more advanced nodes, including 28nm, to cater to automotive and industrial sectors.
- •The project is part of the India Semiconductor Mission (ISM), which provides significant fiscal incentives, including a 50% subsidy on capital expenditure for semiconductor fabs.
- •Tata Electronics is simultaneously developing an Assembly, Testing, Marking, and Packaging (ATMP) unit in Jagiroad, Assam, to create an integrated semiconductor ecosystem within India.
- •The 90nm process technology, while considered legacy, remains highly relevant for power management ICs, microcontrollers, and IoT devices, which constitute a large portion of India's domestic chip demand.

Technical Deep Dive
- The Dholera fab utilizes a 300mm wafer manufacturing process, which is the industry standard for high-volume production.
- The 90nm process node is a mature CMOS technology node, often used for its cost-effectiveness and reliability in non-compute-intensive applications.
- The facility is expected to employ deep ultraviolet (DUV) lithography systems, which are sufficient for 90nm and can be adapted for nodes down to 28nm.
- The manufacturing process involves complex multi-layer metal interconnects and chemical mechanical planarization (CMP) steps typical of standard foundry operations.
Future ImplicationsAI analysis grounded in cited sources
Tata Electronics will achieve 28nm production capability by 2028.
The partnership with PSMC includes a technology transfer roadmap that targets the transition from legacy nodes to 28nm to meet growing demand for automotive and consumer electronics.
The Dholera fab will reduce India's semiconductor import bill by at least 10% within five years.
By localizing the production of high-volume legacy chips, India can substitute a significant portion of its current imports for power management and industrial control components.
