Photolithography
Save
Photolithography is a widely utilized technique in the microfabrication. It is a key step in the production of integrated circuits, microprocessors, and various other electronic devices. Photolithography involves the transfer of geometric patterns from a mask (reticle) to a light-sensitive material (photoresist) on the surface of a substrate. UV light is used for selectively exposing the photoresist to create a desired pattern of exposed and unexposed areas. The exposed areas are then removed during the development process, resulting in the transfer of the pattern onto the substrate.
