Sputter: Basic Function - Nanofabrication: Vacuum Pumps and Thin Film There are many different ways to deposit materials such as metals, ceramics, and plastics onto a surface (substrate) and to form a thin film. Evaporation refers to the heated source material being evaporated in a vacuum. The substrate is placed in a vacuum chamber with the source material, named a target, and an inert gas (such as argon) is introduced at low pressure. The negative charge is applied to a target source material that will be deposited onto the substrate causing the plasma to glow. The atomic weight of the .
