Physical Vapor Deposition (PVD) is a collective set of processes used to deposit thin layers of material, typically in the range of few nanometers to several micrometers. 1 PVD processes are environmentally friendly vacuum deposition techniques consisting of three fundamental steps (Figure 1):n both evaporation and sputtering, the resulting vapor phase is subsequently deposited onto the desired substrate through a condensation mechanism. 2. Deposited films can span a range of chemical compositions based on the source material(s). Further compositions are accessible through reactive deposition processes.
