Comments:
  • The substrate is placed in a wet chemical solution containing ions of the material to be deposited. An electrical potential is applied between a metal seed layer on the substrate and a counter electrode in the liquid to induce a redox process (reduction/deposition at seed layer, oxidation at counter electrode). The electrical potential is varied over time (pulsed) to improve the uniformity of the deposition. The process is typically performed on one side of the substrate at a time.
