Abstract:
Apparatus for electroplating a workpiece, comprising:an anode, and a cathode for supporting the workpiece, wherein the anode and cathode are immersed in a solution, for generating an electric field emanating from the anode towards the cathode, to generate a corresponding current to deposit an electroplating material an the workpiece during an electroplating process; and a selective anode shield/material flow assembly located between the anode and the cathode, and forming a multitude of adjustable openings, said multitude of adjustable openings laterally extending across the anode, and the openings having sizes that are adjustable during the electroplating process for selectively and controllably adjusting the amount of electric flux passing through the shield/material flow assembly and the distribution of the electroplating material across the workpiece.
