What is the significance of Micron’s ATMP semiconductor facility in Sanand for India’s semiconductor ambitions?

Micron’s Assembly, Test, Marking and Packaging (ATMP) facility in Sanand, Gujarat represents an important milestone in India’s efforts to build a domestic semiconductor ecosystem. The plant will assemble and package semiconductor wafers into usable products such as integrated circuit packages, memory modules, and solid-state drives. With an investment of about $2.75 billion, the project demonstrates growing confidence among global technology firms in India as a manufacturing and supply-chain hub.The facility is significant because the ATMP stage is a critical link in the semiconductor value chain. While semiconductor fabrication creates wafers containing multiple chips, the ATMP process converts these wafers into finished components ready for integration into electronic devices. By establishing capabilities in this stage, India can participate more meaningfully in global semiconductor supply chains. The plant is expected to generate direct employment, create supplier opportunities in packaging materials and electronics components, and contribute to export revenues.Moreover, the project signals India’s broader strategic intent to become a reliable partner in the global technology ecosystem. Initiatives such as the Pax Silica agreement and other semiconductor partnerships aim to secure access to critical minerals and advanced technology collaborations. Micron’s investment therefore goes beyond manufacturing; it reflects confidence in India’s policy framework and long-term technological ambitions.However, the plant must also be viewed realistically. It does not involve semiconductor fabrication but focuses on assembly and packaging of wafers produced elsewhere. Nonetheless, as part of a phased approach to building a semiconductor ecosystem, ATMP facilities are often the first step toward deeper technological capabilities. Countries such as Malaysia and Vietnam followed a similar path before expanding into more advanced semiconductor manufacturing activities.

Why is developing a domestic semiconductor ecosystem important for India’s economic and strategic security?

Semiconductors are the backbone of the modern digital economy, powering everything from smartphones and automobiles to defence systems and artificial intelligence infrastructure. As a result, the ability to access reliable semiconductor supplies has become a matter of both economic competitiveness and national security. For a country like India, which has a rapidly growing electronics market, dependence on imports exposes the economy to supply disruptions and geopolitical risks.The global semiconductor supply chain is highly concentrated. Countries such as Taiwan, South Korea, and the United States dominate chip fabrication, while key equipment and design capabilities are controlled by a limited number of firms. During the COVID-19 pandemic, disruptions in semiconductor production led to severe shortages in industries such as automobiles and consumer electronics. These events highlighted the vulnerability of countries that rely heavily on imported chips.Developing a domestic semiconductor ecosystem offers several advantages:Economic growth: The semiconductor industry generates high-value employment and technological innovation.Strategic autonomy: Domestic capabilities reduce dependence on foreign suppliers for critical technologies.Industrial development: Semiconductor manufacturing supports sectors such as electronics, telecommunications, and defence.For India, which aims to become a major global manufacturing hub, strengthening semiconductor capabilities is essential. The government’s semiconductor mission, production-linked incentive schemes, and partnerships with global firms aim to integrate India into global value chains. While achieving full technological independence may be unrealistic in the short term, developing capabilities across different stages of the semiconductor value chain can significantly enhance India’s resilience and competitiveness.

How is India attempting to build a comprehensive semiconductor ecosystem beyond assembly and packaging?

India’s semiconductor strategy involves developing capabilities across multiple segments of the semiconductor value chain rather than focusing solely on assembly and packaging. The government has launched the India Semiconductor Mission to attract investments in fabrication, packaging, design, and supporting infrastructure.A key component of this strategy is the establishment of semiconductor fabrication plants. For example, Tata Electronics, in partnership with Taiwan’s Powerchip Semiconductor Manufacturing Corporation, is constructing a fabrication facility in Dholera, Gujarat. This plant is expected to produce chips in the 28 nanometre and larger node categories and target sectors such as automotive electronics, computing, and artificial intelligence. The facility aims to reach production levels of around 50,000 wafer starts per month, which would represent a major step forward in domestic chip manufacturing.In addition to fabrication, India is investing in several assembly and test facilities across states. Projects are underway in Assam, Gujarat, Uttar Pradesh, Odisha, and Punjab. These facilities will strengthen the downstream part of the semiconductor value chain and create an ecosystem of suppliers for packaging materials, testing equipment, and logistics.India is also focusing on human capital development and research. Institutions such as the All India Council for Technical Education (AICTE) have introduced specialised courses in semiconductor design and manufacturing. Over time, these educational initiatives will help create a skilled workforce capable of supporting high-precision semiconductor operations.Through this multi-layered approach—combining fabrication projects, packaging facilities, skill development, and international partnerships—India aims to gradually build a comprehensive semiconductor ecosystem integrated with global supply chains.

What are the major technological and structural challenges preventing India from producing advanced semiconductor chips?

Despite recent progress, India faces several technological and structural challenges that limit its ability to produce advanced semiconductor chips in the 3–5 nanometre range. Semiconductor fabrication at such advanced nodes requires extremely sophisticated equipment, specialised materials, and highly skilled personnel, all of which are concentrated in a few countries.One major constraint is the lack of access to advanced lithography technology. Extreme ultraviolet (EUV) lithography machines—essential for producing cutting-edge chips—are manufactured by a limited number of suppliers, most notably ASML in the Netherlands. These machines cost hundreds of millions of dollars and are subject to export controls and geopolitical restrictions.Another challenge is the limited availability of advanced packaging technologies such as Chip-on-Wafer-on-Substrate (CoWoS) and High-Bandwidth Memory (HBM). These technologies are crucial for high-performance computing and artificial intelligence applications. Currently, global capacity for these advanced packaging techniques is concentrated in a few firms, particularly in Taiwan and South Korea.Infrastructure constraints also play a role. Semiconductor fabrication plants require stable electricity supply, ultra-pure water, specialised chemicals, and precision logistics systems. Establishing and maintaining such infrastructure demands significant investment and long-term planning.Finally, there is a shortage of experienced semiconductor engineers and technicians in India. While the country has strong capabilities in chip design and software engineering, manufacturing operations require specialised training and operational experience. Addressing these challenges will require sustained policy support, international collaboration, and long-term investment in education and infrastructure.

Critically analyse the strategy of focusing on mature-node semiconductor manufacturing in India.

India’s current semiconductor strategy emphasises manufacturing chips in the 28–110 nanometre range, commonly referred to as mature-node semiconductors. These chips are widely used in sectors such as automobiles, industrial equipment, power electronics, and consumer appliances. While this approach may appear less ambitious compared to cutting-edge chip production, it has several strategic advantages.Advantages of the mature-node strategy include:Lower capital requirements: Fabrication plants for mature nodes require less expensive equipment compared to advanced-node facilities.Large global demand: Industries such as automotive manufacturing continue to rely heavily on mature-node chips.Reduced technological barriers: Countries entering the semiconductor sector can build capabilities more gradually.However, there are also limitations to this approach. A study by the Indian Electronics & Semiconductor Association suggests that by 2032 nearly 60% of India’s semiconductor demand could be for chips below 10 nm, driven by smartphones, data centres, and artificial intelligence infrastructure. This means India may still rely heavily on imports for high-end chips even if domestic mature-node manufacturing expands.Furthermore, global competition in mature-node manufacturing is intense, particularly from China and Southeast Asian countries. To remain economically viable, Indian producers may need to export a significant share of their production to international markets.Despite these challenges, focusing on mature nodes is a pragmatic entry strategy. It allows India to develop manufacturing expertise, supply-chain networks, and skilled manpower before moving toward more advanced technologies in the future.

Imagine you are a policymaker tasked with strengthening India’s semiconductor ecosystem over the next decade. What policy measures would you prioritise?

If tasked with strengthening India’s semiconductor ecosystem, a policymaker would need to adopt a comprehensive strategy addressing technology, infrastructure, and human capital. Semiconductor manufacturing is one of the most complex industrial sectors, and success requires coordinated policy support over many years.First, infrastructure development must be prioritised. Semiconductor fabs require uninterrupted power supply, large quantities of ultra-pure water, and advanced logistics networks. Establishing specialised semiconductor manufacturing zones with dedicated infrastructure would reduce operational risks and attract global investors.Second, the development of backward supply chains is crucial. Semiconductor production depends on a wide range of supporting industries, including specialty gases, chemicals, silicon wafers, and maintenance services. Encouraging domestic production of these inputs through incentives and joint ventures can reduce dependence on imports and strengthen the ecosystem.Third, human capital development must be accelerated. Expanding specialised education programmes in semiconductor engineering and encouraging collaboration between universities and industry can help create a skilled workforce. Initiatives such as AICTE’s semiconductor courses are a positive step, but scaling them nationwide is essential.Finally, government procurement—particularly in the defence and strategic sectors—can provide assured demand for domestically produced chips. Defence electronics, which often use mature-node semiconductors, could anchor early domestic production.Through a combination of infrastructure investment, supply-chain development, skill formation, and strategic demand creation, India can gradually establish a resilient semiconductor ecosystem integrated with global technology networks.
