- Investigation of the Variable Rotation Polishing Efficiency
抄録
In this study, a novel Variable Rotation Polishing method would be proposed in order to increase the unsteady slurry flow in CMP process for increasing the polishing efficiency and for flowing slurry into the center of wafer sufficiently when the wafer becomes larger and also in case of saving the slurry. We developed a control unit to control platen variable rotation speed and rotation direction and rotation angle. This paper investigates the efficiency of variable rotation in CMP process. Consequently, material removals of all conditions in case of Variable Rotation Polishing were higher than only forward rotation.
