In a bold step towards reshaping India’s semiconductor future, a team of scientists from the Indian Institute of Science (IISc) has submitted a proposal to develop angstrom-scale chips using advanced two-dimensional (2D) materials. These ultra-small chips—potentially one-tenth the size of today’s most advanced 3nm chips—could propel India to the forefront of global semiconductor innovation. The project seeks Rs. 500 crore over five years and aims to reduce India's dependency on foreign technology. As global powers double down on post-silicon research, India’s response may determine its place in the high-stakes race for next-generation computing supremacy.
India's Semiconductor Pivot: From Silicon to 2D Materials
The proposal from IISc envisions a future where India does not merely participate in the semiconductor revolution but defines it. Angstrom-scale chips—smaller than nanometer nodes currently in commercial production—represent the next frontier in chip fabrication. At the core of this transformative initiative lies a new class of materials: 2D semiconductors such as graphene and transition metal dichalcogenides (TMDs).
These ultra-thin compounds have unique electronic, thermal, and mechanical properties that make them ideal for post-silicon computing technologies. Unlike traditional silicon, 2D materials enable atomic-level control over thickness, enabling engineers to push performance limits beyond current technological boundaries.
Strategic and Scientific Vision Behind the IISc Proposal
The IISc team submitted its detailed project report (DPR) to the Principal Scientific Adviser (PSA) in April 2022, revising and resubmitting it in October 2024. The plan is now under active review by the Ministry of Electronics and Information Technology (MeitY), signaling possible government endorsement.
The proposal outlines a five-year roadmap, requesting Rs. 500 crore in funding—a fraction of the investment India is making in large-scale silicon fabs like the Rs. 91,000 crore Tata-PSMC project in Gujarat. But while that project focuses on near-term silicon production, the IISc effort is a bet on India’s long-term technological sovereignty.
Sources within MeitY have described the plan as promising, with discussions held among senior officials to identify high-impact applications and align efforts with national objectives, including the India Semiconductor Mission.
Global Momentum in 2D Semiconductors
India is not alone in exploring this promising field. Europe has committed over USD 1 billion (Rs. 8,300 crore) toward research in 2D materials. South Korea has invested over USD 300 million, while China and Japan have poured undisclosed but significant resources into similar initiatives.
The urgency is growing because conventional silicon technology is approaching its physical and economic limits. As Moore’s Law slows, leading tech nations are turning to 2D materials to build heterogeneous computing systems that can integrate memory, logic, and sensing elements more efficiently than ever before.
India’s efforts, however, have so far been limited to discussions and policy deliberation. According to insiders, the window for strategic advantage may close quickly if decisive action is not taken soon.
Advantages and Applications of Angstrom-Scale Chips
Angstrom-scale chips promise not only increased computational power but also reduced energy consumption, higher integration density, and greater flexibility in design. These chips could be critical for:
- Artificial Intelligence (AI) and Machine Learning
- Quantum Computing Interfaces
- Defense and Aerospace Systems
- Medical Diagnostics and Wearables
- 5G/6G Communications Infrastructure
The potential cross-sectoral applications make these chips strategically vital. Additionally, the district cooling-like efficiency gains seen in energy usage could help India's technology stack become more sustainable.
India’s Semiconductor Ecosystem: The Next Step
Currently, India remains largely dependent on imports for advanced semiconductors, a vulnerability highlighted during the COVID-era global chip shortage. Although the government has taken commendable steps to build a domestic fabrication ecosystem, including subsidy packages and strategic alliances, these efforts remain largely silicon-focused.
The IISc-led proposal seeks to future-proof India’s position in this strategic sector. Communications have already been initiated with ministries such as MeitY, DRDO, and the Department of Space, alongside endorsements from policy think tanks like NITI Aayog.
The project also promises self-sufficiency post-funding, aiming to catalyze a new generation of startups and research labs in India’s silicon valleys—from Bengaluru to Hyderabad.
Conclusion: The Future Hinges on Urgency and Vision
As the world races toward post-silicon computing, India stands at a defining moment. The angstrom-scale chip initiative, led by IISc, offers not only technological prestige but also a pathway to strategic autonomy in one of the most critical domains of the 21st century. The required investment—Rs. 500 crore—is modest compared to its transformative potential.
But in the rapidly evolving world of semiconductors, hesitation is a luxury India can ill afford. The question now is whether New Delhi will choose deliberation or decisive action—and whether the promise of a new material future will become a national reality.
