India’s ambitious quest to establish itself as a global semiconductor manufacturing hub is taking a crucial step forward with Tata Electronics Pvt. Ltd., the technology arm of the venerable Tata Group, commencing its foray into chip fabrication. This monumental undertaking, aimed at mitigating the nation’s profound dependence on imported semiconductors, is poised to initiate production using process technologies that are significantly older than initially envisioned, underscoring the formidable complexities inherent in building a sophisticated chip industry from the ground up. The Dholera facility in Gujarat, earmarked as the cornerstone of this strategic initiative, is reportedly preparing to produce wafers primarily based on 90-nanometer (nm) process technology, a decision that reflects a pragmatic, albeit cautious, approach to entering one of the world’s most capital-intensive and technologically intricate sectors.
The initial technological choice of 90nm represents a considerable departure from the 28nm node that Tata Sons Pvt. Ltd., the group’s holding company, had previously highlighted as its intended starting point in its annual report for the fiscal year ended March 2025. While a spokesperson for Tata Electronics clarifies that the Dholera fab will span technologies from 28nm to 110nm, with a plan to "always start with 55nm and 90nm, followed by 28nm," the initial emphasis on more mature nodes signals a strategic de-risking maneuver. Powerchip Semiconductor Manufacturing Corp. (PSMC) of Taiwan, Tata’s key technology partner, corroborates this phased approach, noting that a gradual introduction of technology platforms, beginning with mature nodes, is a common industry practice. This pragmatic start, however, positions Tata Electronics in a segment of the market that, while critical, is less lucrative than the cutting-edge processes that dominate headlines and drive significant revenue for industry leaders.
To understand the implications, it is crucial to differentiate between these process nodes. A nanometer (nm) refers to the gate length of a transistor, with smaller numbers indicating more advanced technology, higher transistor density, improved performance, and reduced power consumption. The 90nm node, introduced commercially in the early 2000s, is considered a highly mature technology. Its applications primarily lie in industrial control systems, older consumer electronics, specific automotive components, and various Internet of Things (IoT) devices that do not demand high computational power or extreme energy efficiency. In contrast, the 28nm node, a workhorse of the industry since the early 2010s, remains a commercially vital process for a vast array of products, including smartphones, communications equipment, mainstream consumer electronics, and a growing segment of automotive microcontrollers and infotainment systems. While 90nm risks obsolescence in certain high-volume consumer markets, its enduring relevance in specific, long-lifecycle industrial and automotive applications ensures a steady, albeit lower-margin, demand.
The decision to commence with older nodes underscores the steep learning curve faced by the Tata Group. Despite its formidable manufacturing prowess across diverse sectors, from luxury automobiles to industrial chemicals, the intricacies of semiconductor fabrication present a unique set of challenges. Chipmaking demands ultra-precise environments, proprietary intellectual property, highly specialized equipment costing billions of dollars, and an exceptionally skilled workforce. By starting with 90nm and 55nm, Tata can build foundational capabilities, develop operational expertise, and train a talent pool in a less technologically demanding environment before transitioning to more complex 28nm processes and potentially beyond. This "crawl-walk-run" strategy is a common playbook for new entrants in high-tech manufacturing, allowing for the absorption of complex processes in a controlled manner.
India’s drive for semiconductor self-reliance is not merely an economic aspiration but a geopolitical imperative. The global chip shortage experienced during the COVID-19 pandemic vividly exposed the vulnerabilities of highly concentrated supply chains, particularly the world’s reliance on a few key players in East Asia. Nations worldwide are now racing to localize semiconductor manufacturing to enhance supply chain resilience, foster technological sovereignty, and secure their national economic interests. For India, a nation with a burgeoning digital economy and a growing manufacturing base, indigenous chip production is vital for everything from defense applications to consumer electronics and electric vehicles. Prime Minister Narendra Modi’s government has vigorously championed this cause, recognizing semiconductors as foundational to the nation’s future economic growth and strategic autonomy.
To accelerate this vision, New Delhi has rolled out substantial financial incentives. The India Semiconductor Mission (ISM), launched in 2021, initially offered a $10 billion aid package designed to cover up to 50% of the project cost for setting up semiconductor fabrication plants, assembly, testing, marking, and packaging (ATMP) units, and design-linked incentive schemes. Tata’s Dholera fab, with a planned capital expenditure of $10.7 billion, is a direct beneficiary of this scheme. More recently, the government approved an additional ₹1.28 trillion (approximately $15 billion) in new state aid aimed at supporting chip design, manufacturing equipment, and supply-chain development. However, this fresh tranche of funding is earmarked for future, incremental investments, not retroactively offsetting already committed spending, indicating a sustained, long-term commitment to nurturing the ecosystem.
Despite these significant policy interventions and financial commitments, the challenges remain formidable. The semiconductor industry is characterized by its capital intensity, requiring billions of dollars for a single fabrication plant. Moreover, the sector demands highly specialized infrastructure, including uninterrupted power supply, ultra-pure water, and pristine cleanroom environments. Perhaps the most critical hurdle for a nascent industry like India’s is the acute shortage of skilled talent—engineers, scientists, and technicians with expertise in chip design, fabrication, and advanced materials. India’s robust IT services sector has not historically focused on hardware manufacturing at this level of complexity, necessitating significant investment in education, training, and talent repatriation programs.
Globally, India is entering a highly competitive arena dominated by established giants with decades of head start. Taiwan Semiconductor Manufacturing Co. (TSMC), the world’s leading foundry, has already begun volume production at the 2nm node and derives the vast majority of its revenue from nodes 5nm and smaller. South Korea’s Samsung Foundry and the United States’ Intel are also pushing the boundaries of advanced manufacturing. India’s starting point with 90nm and 55nm is therefore several generations behind the cutting edge. However, it is crucial to recognize that not all chips need to be bleeding-edge. The global demand for mature nodes remains robust, driven by the automotive industry, industrial IoT, power management integrated circuits, and legacy electronics. The push for supply chain diversification has also made countries like the U.S. and Europe invest heavily in mature node production within their borders. By initially targeting this segment, Tata Electronics can serve a vital, underserved market while systematically building its capabilities.
The long-term economic impact of Tata’s semiconductor foray, irrespective of its initial technological constraints, promises to be transformative for India. A domestic chip industry will create thousands of direct, high-skill jobs in manufacturing and R&D, and exponentially more indirect jobs in ancillary industries such as materials supply, equipment maintenance, logistics, and design services. It will foster a vibrant ecosystem of innovation, encouraging the growth of local startups in chip design and related fields. Reducing import dependence on semiconductors, currently a significant drain on foreign exchange, will improve India’s trade balance and enhance its economic resilience. Furthermore, it strengthens national security by ensuring a domestic supply of critical components for strategic sectors.
The revised timeline for commercial operations at the Dholera plant, now expected in mid-2028 from an earlier target of end-2026, further illustrates the inherent complexities and time-consuming nature of fab construction and ramp-up. Such delays are not uncommon in this industry, even for seasoned players. However, this extended timeline also provides Tata Electronics and its partners with additional opportunities to refine their processes, secure necessary equipment, and further train their workforce. The Dholera facility, strategically located within the Gujarat Semiconductor Policy framework, aims to become a cornerstone of India’s semiconductor ambitions, attracting further investment and talent to the region.
In conclusion, Tata Electronics’ entry into semiconductor manufacturing, beginning with mature process technologies, represents a pragmatic and strategically sound approach for India to establish a foothold in this critical industry. While the initial technological choices may appear modest compared to global leaders, they signify a measured, de-risked pathway to acquiring foundational expertise, building a skilled workforce, and securing a vital segment of the global chip supply chain. This endeavor is more than just a business venture for the Tata Group; it is a national undertaking, backed by substantial government support, poised to lay the groundwork for India’s technological sovereignty and industrial future in an increasingly digitized world. The journey will be long and arduous, marked by continuous learning and significant investment, but the strategic imperative for India could not be clearer.
