Microfabrication refers to the process of creating structures on a microscopic scale, typically using a combination of techniques such as lithography, etching, and deposition. This specialized skill is used in a variety of fields, including electronics, biotechnology, and materials science, to create microchips, microelectromechanical systems (MEMS), lab-on-a-chip devices, sensors, and other small-scale components. The process is highly precise and requires the use of specialized equipment and materials, making it a specialized skill that requires significant training and expertise.
