A photoresist (also known simply as a resist) is a light-sensitive material used in several processes, such as photolithography and photoengraving, to form a patterned coating on a surface. This process is crucial in the electronic industry. The process begins by coating a substrate with a light-sensitive organic material. A patterned mask is then applied to the surface to block light, so that …

WebSep 30, 2024 · The recipes of such photoresists are well optimized for a uniform thickness across the wafer. However, special thick photoresists are used as a sacrificial layer for MEMS devices.
