Comments:
  • The substrate is placed at room temperature in a low-pressure chamber between two electrodes (the cathode and anode). A large DC potential is applied between the electrodes, which causes a plasma and ionization of the gas (e.g., argon) between the electrodes. The ions bombard the cathode (named the target) causing atoms to be knocked off the target and condense on the substrate surface. A strong magnetic field is applied to contain the plasma near the surface of the target to increase the deposition rate. The process is typically performed on one side of the substrate at a time and can only be used to deposit conductive materials.
