Angstrom-scale semiconductor chips are the next frontier in miniaturizing electronics—pushing beyond the current 3-nanometer (nm) technology into the realm of angstroms, where 1 angstrom equals just 0.1 nm.
To put that in perspective: if today’s most advanced chips are like a grain of rice, angstrom-scale chips are like a single grain of salt. These chips aim to pack more transistors into a smaller space, dramatically boosting performance while reducing power consumption.
Since traditional silicon struggles at such tiny scales, researchers are turning to 2D materials like graphene and transition metal dichalcogenides (TMDs). These materials are just one atom thick, yet they offer exceptional conductivity, flexibility, and thermal stability—perfect for building ultra-efficient chips.
India is quietly preparing to leapfrog into the future of semiconductors—and it’s not just chasing nanometers anymore. It’s going angstrom-deep.
In a bold proposal, a 30-member team from the Indian Institute of Science (IISc) has pitched a ₹500-crore, 5-year mission to craft angstrom-scale semiconductor chips, venturing where even 3nm technology begins to fade. These chips, which measure in tenths of a nanometer, are set to defy the limits of traditional silicon, aiming for devices that are faster, cooler, and up to 10x smaller.
It is to be noted that this angstrom-scale chip initiative echoes the momentum we saw back in April 2025, when India’s semiconductor ambitions were making headlines for multiple reasons. In that month, Union Minister Ashwini Vaishnaw announced that India’s first Made-in-India semiconductor chip would be ready by the end of 2025.
This proposal for angstrom-scale chip was first submitted to the Principal Scientific Adviser in 2022, revised in 2024, and now under active review by the Ministry of Electronics and IT (MeitY).

Backed by the Anusandhan National Research Foundation (ANRF), this angstrom-scale chip initiative aligns with the Indian government’s larger push toward next-gen R&D and self-reliance in critical technologies. If greenlit, it could signal India’s emergence as a serious player in the post-silicon era—joining a global race led by the U.S., South Korea, and Taiwan.
Imagine a future where India's edge isn’t just in software, but at the molecular level of hardware. That future might just be a few angstroms away.
India’s angstrom-scale chip initiative and its GPU-powered AI mission are two sides of the same silicon coin—one building the hardware of tomorrow, the other fueling the intelligence of today. Together, they could reshape India’s technological sovereignty across sectors.
How It Ties into IndiaAI’s GPU Push
The IndiaAI Mission has deployed 34,000+ high-performance GPUs to power foundational models, LLMs, and AI applications tailored to Indian languages and needs. But as AI models grow more complex, they demand denser, faster, and more energy-efficient chips—precisely what angstrom-scale semiconductors promise.By investing in angstrom-scale R&D, India is laying the groundwork for next-gen AI accelerators that could outperform today’s GPUs in speed and efficiency. Imagine training a 120 Billion-parameter LLM not in weeks, but in days—with a fraction of the energy.
Angstrom-scale chips could power ultra-compact, secure edge devices for surveillance, autonomous drones, and encrypted battlefield communications. With DRDO already looped into the IISc proposal, the defense implications are clear: faster, stealthier, smarter systems.
From real-time climate modeling to smart grid optimization, these chips could enable low-power sensors and AI models that run in remote or harsh environments. Think satellite-based carbon tracking or AI-driven disaster prediction—all on chips smaller than a virus.
In diagnostics and wearables, angstrom-scale chips could lead to implantable biosensors, AI-assisted imaging, and personalized medicine. Their low heat and power footprint make them ideal for continuous health monitoring—even inside the body.
In essence, India isn’t just scaling up compute with GPUs—it’s redefining the substrate of intelligence itself. Want to explore how this could position India as a global chip design hub or how it compares to what the U.S. and South Korea are doing?
If successful, angstrom-scale chips could power everything from quantum computers to AI systems, wearables, and space tech, all while using less energy and generating less heat.
