Thin film deposition technology is used to deposit thin film materials onto the surface of a substrate and is a key process in industries such as microelectronics, optoelectronics, and nanotechnology.
Thin film deposition is generally divided into physical and chemical methods, which complement each other.

Physical methods mainly involve depositing metal wires and compound films, while chemical methods (such as chemical vapor deposition) are used to deposit films through reactions between gases. Some chemical methods can also be used to deposit metal films.

Thin film deposition processes are typically carried out in a vacuum environment, where ultra-pure process gases and inert gases must be introduced. In addition, wafer transfer between process chambers, load chambers, and transfer chambers involves vacuum breaking operations, all of which must be conducted in extremely clean and stable environments.

1) Physical Vapor Deposition (PVD)
PVD mainly converts raw materials into a gaseous state through physical processes such as evaporation and sputtering, and deposits thin films onto the substrate surface.

2) Chemical Vapor Deposition (CVD)
CVD is the process of converting vapor-phase precursors into solid thin films through chemical reactions, which are deposited onto the surface of the substrate.
