Shrinking devices, expanding possibilities

Abstract

A 3-nanometre transistor is no longer science fiction; it is inside the phone in your pocket. Yet classical silicon is gasping. The next leap will come from nanoelectronics: new materials, new device physics, and integration at atomic precision. This includes today’s scaled CMOS, powering everything from AI chips to edge devices. This is not just about making chips smaller. It is about making them smarter, cheaper, and greener.

The global nanoelectronics market, encompassing scaled CMOS semiconductors, sensors, and IoT edge devices, is heading toward $1 trillion by 2030. Nanosensors already detect a single virus particle. Ultra-low-power chips enable IoT networks that run for ten years on a coin cell. Flexible electronics printed on plastic will turn any surface into a display or a health monitor. From electric-vehicle powertrains to satellite constellations, every high-growth sector rides this wave.
