WebMar 9, 2024 · Thin-Film Thermal Deposition Explained. Thermal evaporation is a common physical vapour deposition (PVD) method. This basic form of PVD involves the use of resistive heating at high temperatures in a high vacuum chamber to cause solid material evaporation and create high vapour pressure. Then, the stream of evaporated material … WebHigh Vacuum (HV) usually stands for the pressure between 10 -3 Torr to 10 -8 Torr range. Once the pressure reaches below the 10 -8 Torr range, it can be considered as Ultra High Vacuum (UHV). If the pressure is further reduced to below the 10 -12 Torr range, it will enter the Extreme High Vacuum (XHV) range.
