PVD and CVD are coating techniques, which we can use to deposit thin films on various substrates. Coating of substrates is important on many occasions. Coating can improve the functionality of the substrate ...
WebThe PVD thin film deposition process is a plasma coating process where atoms are ejected from target material and moved to target surface. The whole process takes place in a vacuum chamber filled with inert gas. After applying high voltage plasma conditions are created.

A thin film deposition apparatus comprising; a hollow cathode, a substrate holder and a target holder, the substrate holder and the target holder being located on opposite sides of the hollow cathode, a plasma supply element to supply plasma to the interior of the hollow cathode at an end of the hollow cathode nearest the target holder, and a power unit … WebThermal Evaporation Solutions. Thermal evaporation is a common method of physical vapor deposition (PVD). It is one of the simplest forms of PVD and typically uses a resistive heat source to evaporate a solid material in a vacuum environment to form a thin film. The material is heated in a high vacuum chamber until vapor pressure is produced.
