Abstract:
A method of depositing a conductive material from an electrolyte solution of a workpiece having a top surface and a cavity portion disposed on the top surface and having a conductive layer disposed on the top surface and the cavity portion of the workpiece comprising the steps of:applying a potential difference between the workpiece and an anode, with the workpiece being positioned in proximity to the anode, thereby causing the application of the conductive material to at least the conductive layer disposed on the cavity portion of the workpiece; andminimizing accumulation of the conductive material to the conductive layer disposed on the top surface of the workpiece by polishing the the conductive layer disposed on the top surface of the workpiece with a pad while the application of the conductive material is occurring.
