Electron Beam Evaporator 2

This principle is the same for all thermal evaporation technologies, only the method used to heat the source material differs. There are two popular evaporation technologies, which are resistive evaporation and electron beam evaporation. Thermal evaporation depositions are vacuum-based processes where a focused electron beam or high current melts or evaporates a target material. Once vaporized, it reaches without collision (high vacuum) the substrate and then condenses onto it to form a thin film with controlled properties, the substrate being upside down. The thickness is monitored in live using crystal quartz balance.
