DIY Physical Vapor Deposition (PVD) using Thermal Evaporation

This video discusses the building process of a system for doing Physical Vapor Deposition (PVD). 0:00 Intro 1:09 Thin film technology 1:56 Principle of PVD 3:22 Limitations of thermal evaporation 4:48 Thermal source construction 5:50 Required vacuum conditions 7:25 System layout and construction 9:25 Turbo screw up 10:25 Technical aspects 12:02 Plasma cleaning 14:02 Quick evaporation tests Apart from some technical aspects of the machine, I also discuss the background of thermal evaporation as a technique to do PVD. The system will be used in the future to make small optical devices using photolithography.
