摘要
Wafer-scale profile evolution of electrochemically deposited copper films is experimentally studied and compared with theoretical predictions. The effects of ohmic potential drop, electrochemical current-voltage behavior at the metal/electrolyte interface, and local concentration variations are considered. Results show good agreement with experimental data over a wide range of total currents and times. (C) 2003 The Electrochemical Society.
