Integrated Circuit (ic) - Nanotechnology

What is an Integrated Circuit (IC)?

An integrated circuit (IC) is a set of electronic circuits on a small flat piece of semiconductor material, typically silicon. ICs can function as amplifiers, oscillators, timers, counters, computer memory, and microprocessors. They are fundamental building blocks of modern electronic devices, enabling the miniaturization and enhancement of electronic systems.

How Does Nanotechnology Enhance ICs?

Nanotechnology involves the manipulation of matter on an atomic, molecular, and supramolecular scale. When applied to ICs, nanotechnology enables the creation of smaller, faster, and more efficient components. This enhancement is achieved through the development of new materials, such as carbon nanotubes and graphene, and advanced fabrication techniques like electron-beam lithography.
