Photolithography is a key process used in various fields, particularly in semiconductor manufacturing, to transfer geometric patterns onto a substrate. The technique involves several steps and is essential for fabricating integrated circuits (ICs) and microstructures. \#\#\# Key Steps in Photolithography: 1. **Coating**: A photosensitive material called photoresist is applied to the surface of a substrate, such as a silicon wafer.
