Electroplating theory
WebSep 15, 2024 · The binding energy between zinc and the additives is calculated by density functional theory (DFT) to verify the contribution of additives in the electroplating process. Following a long-term plating session for 8 h, depletions of zinc and additives are found to largely affect brightness and surface morphology of the electrodeposited zinc surface. WebNov 22, 2016 · The concept of copper electroplating is straightforward: Submerge the wafer to be plated into an electrolyte bath, apply a current, and copper ions will migrate and deposit onto regions with a pre-existing metal seed layer. The electrolyte bath contains three primary inorganic components: Copper sulfate (CuSO4) provides a source of copper ions.
