Comments:
  • The substrate is placed in a high vacuum chamber at room temperature with a crucible containing the material to be deposited. A high electrical current is applied through the tungsten crucible, heating it up beyond the boiling point of the material to be deposited, thereby causing it to evaporate and condense on all exposed cool surfaces on the vacuum chamber and substrate. The process is typically performed on one side of the substrate at a time.
