High Performance Computing
- HPC refers to the use of supercomputers and parallel processing systems to solve computational problems that ordinary computers cannot handle efficiently.
Exaflop
- An Exaflop means one quintillion (10¹⁸) floating-point calculations per second.
- Gigaflop = 10⁹ operations/sec
- Teraflop = 10¹² operations/sec
- Petaflop = 10¹⁵ operations/sec
- Exaflop = 10¹⁸ operations/sec
- Crossing 2 exaflops represents one of the highest levels of computing capability.
Lessons for India
Build a Complete Semiconductor Ecosystem
- China’s success demonstrates that semiconductor leadership cannot be achieved through fabrication plants alone.
- A globally competitive ecosystem must integrate every stage of the value chain, including chip design, fabrication, manufacturing equipment, raw materials, packaging, testing, software, and a highly skilled workforce.
- India’s focus should therefore be on developing an end-to-end semiconductor ecosystem rather than isolated manufacturing facilities.
Move from Chip Design Services to Indigenous Innovation
- India is already a global hub for semiconductor design, with multinational companies such as Nvidia, Intel, Qualcomm, AMD and Texas Instruments operating major design centres.
- The next step is to move beyond providing design services for foreign firms and create indigenous processor architectures, intellectual property (IP), and globally competitive semiconductor products.
- This shift will significantly increase value addition and technological sovereignty.
Invest in Long-Term Research and Development
- Sustained investment in research and development is essential for technological leadership.
- India must strengthen research in advanced processor architecture, semiconductor materials, next-generation packaging technologies, artificial intelligence chips, quantum computing, and other emerging technologies.
- Long-term innovation, rather than short-term manufacturing targets, will determine competitiveness.
Develop a Highly Skilled Workforce
- The semiconductor industry depends on specialized human capital.
- India should expand education, training, and industry collaboration in areas such as VLSI design, embedded systems, semiconductor physics, chip verification, fabrication processes, and electronics manufacturing.
- Building a large pool of skilled engineers will support both domestic industries and global investments.
Promote Domestic Innovation and Start-ups
- Innovation should be driven by a strong ecosystem of research institutions, start-ups, and private industry.
- Government support should encourage the development of indigenous AI chips, edge processors, semiconductor equipment, and processor architectures, reducing reliance on imported technologies while fostering globally competitive Indian companies.
Reduce Import Dependence
- India currently depends heavily on imports for semiconductor manufacturing equipment, wafers, specialty chemicals, and electronic components.
- Developing domestic manufacturing capabilities in these critical areas will improve supply-chain resilience, reduce strategic vulnerabilities, and strengthen technological self-reliance.
India Semiconductor Mission (ISM)
- The India Semiconductor Mission (ISM) was launched in 2021 with the objective of transforming India into a global hub for semiconductor manufacturing and electronics production.
- It seeks to create a comprehensive semiconductor ecosystem by supporting fabrication facilities, display manufacturing, compound semiconductors, chip design, packaging and testing infrastructure, and advanced semiconductor research.
Recent Developments
- The mission has gained momentum through the approval of multiple semiconductor projects across different states.
- Major investments include the Tata semiconductor fabrication facility at Dholera, Gujarat, along with the rapid expansion of OSAT (Outsourced Semiconductor Assembly and Testing) facilities.
- These initiatives are strengthening India’s electronics manufacturing ecosystem and laying the foundation for domestic semiconductor production.
Challenges Before India
- High Capital Requirements
- Establishing semiconductor fabrication facilities requires investments running into several billion dollars, making it one of the world’s most capital-intensive industries.
- Technology Gap
- Advanced semiconductor manufacturing technologies remain concentrated in a handful of countries, making technology access and transfer a significant challenge.
- Dependence on Imported Equipment
- India relies heavily on imported semiconductor manufacturing equipment, increasing production costs and exposing the industry to geopolitical risks.
- Weak Supply Chain
- Domestic production of wafers, specialty chemicals, industrial gases, and other critical inputs remains limited, affecting the resilience of the semiconductor ecosystem.
- Shortage of Skilled Professionals
- Rapid expansion of the semiconductor industry requires a much larger pool of engineers and technicians with specialized expertise in chip design, fabrication, and testing.
- Long Gestation Period
- Semiconductor fabrication projects require several years before commercial production begins, demanding sustained policy support and long-term investment.
Opportunities for India
- China Plus One Strategy
- Global companies are diversifying their supply chains beyond China, creating an opportunity for India to emerge as an alternative manufacturing destination.
- Strong Design Capabilities
- India already possesses one of the world’s largest semiconductor design talent pools, providing a strong foundation for moving into advanced manufacturing.
- Growing Domestic Demand
- Rapid growth in electronics, electric vehicles, telecommunications, artificial intelligence, and digital infrastructure is increasing India’s demand for semiconductors.
- Government Policy Support
- Initiatives such as the India Semiconductor Mission, Production Linked Incentive (PLI) Scheme, and ease-of-doing-business reforms are encouraging investment in the sector.
- Strategic International Partnerships
- Collaboration with countries such as the United States, Japan, Taiwan, and European nations can provide access to technology, investment, and resilient semiconductor supply chains.
Way Forward for India
- Build a complete semiconductor value chain.
- Encourage indigenous processor design.
- Increase semiconductor R&D spending.
- Expand engineering education in semiconductor technologies.
- Strengthen academia-industry collaboration.
- Promote domestic semiconductor equipment manufacturing.
- Diversify global technology partnerships.
- Focus on long-term policy stability and innovation-led growth.
