What is a Deposition Unit?
The deposition unit deposits thin films on a surface by sputtering. Sputtering involves eroding material from a target or source onto a substrate, such as a silicon wafer or glass. Sputtering has many applications. In the semiconductor industry, it is used to deposit thin films of various materials during the manufacturing of integrated circuits or to deposit contact metals for thin film transistors. Deposition units also serve to create thin antireflection coatings on glass for optical applications.
