Thermal Evaporation System
Vacuum evaporation is one of the most cost-effective deposition techniques. It’s also one of the oldest techniques, considering that Thomas Edison himself stated “the uses of this invention are unlimited.”
Edison was not correct, however, as thermal evaporation has a number of limitations including evaporation temperature, composition of alloys and compounds and life of the source. Recently, thermal evaporation has found numerous applications for depositing organic materials such as OLED (Organic light emitting diodes).
