Nanofabrication refers to the processes used to create structures or devices with dimensions on the nanometer scale, typically between 1 and 100 nanometers. This scale is relevant because at these sizes, materials can exhibit unique physical, chemical, and biological properties that differ significantly from their bulk counterparts. Nanofabrication techniques are essential for the development of a wide range of advanced technologies.

There are two primary approaches to nanofabrication: top-down and bottom-up. Top-down methods start with larger materials and reduce them to the nanoscale through processes like lithography (photolithography, electron-beam lithography), etching, and milling. Photolithography, for example, uses light to transfer a pattern onto a substrate, which is then selectively removed. Bottom-up approaches involve assembling nanoscale components, such as atoms or molecules, into larger structures. Examples include self-assembly, chemical synthesis, and molecular printing.

The applications of nanofabrication are diverse and growing. In electronics, it enables the creation of smaller, faster, and more energy-efficient transistors, leading to advanced microprocessors and memory devices. In medicine, nanofabrication is used to develop targeted drug delivery systems, advanced diagnostic tools, and biocompatible implants. Other fields benefiting from nanofabrication include materials science for creating novel composites and coatings with enhanced properties, and energy for developing more efficient solar cells and batteries. The precision and control offered by nanofabrication are key to unlocking the potential of nanotechnology.
