| Low-Temperature Operation: Designed for materials with low melting points to prevent overheating and premature evaporation.High-Vacuum Environment (HV/UHV): Maintains high vacuum to minimize impurities, as indium easily oxidizes and acts as a getter.Cryogenic-Compatible Deposition: Produces high-purity, low-stress, and stable thin films suitable for quantum computing applications.Controlled Film Thickness: Provides high-precision thickness control for nanometer-scale junctions.Suppression of "Overspray": Features specialized shielding to prevent indium (which has a tendency to stick to surfaces) from coating the chamber walls.
Evaporation Source (Source Heater): Uses a resistive boat or basket made of Tungsten (W) or Molybdenum (Mo).Crucible Liners: Alumina, Graphite  Liquid-Cooled Stage/Substrate Holder: A cooling system (using water or liquid nitrogen) keeps the substrate cold to prevent indium film melting and to control grain size.Water-Cooled Shroud: A surrounding shield to contain the evaporation plume, preventing contamination of the chamber.Crystal Monitor (QCM): A Quartz Crystal Microbalance for real-time monitoring of the indium deposition rate and thickness.Shielding/Flux Masking: Removable liners or foils to manage the high sticking coefficient of indium.
