A polishing method is used for polishing a surface of a substrate such as a semiconductor wafer. The polishing method includes a polishing process for polishing a surface of the substrate in accordance with a preset polishing recipe, a pad cleaning process for removing foreign matters on the polishing pad by ejecting a cleaning fluid onto the polishing pad, and a substrate transferring process in which the polished substrate is removed from the top ring at a substrate transferring position, a subsequent substrate to be polished is loaded onto the top ring, and then the top ring holding the subsequent substrate to be polished is returned to the polishing table. The pad cleaning process is started after the completion of the polishing recipe is detected, and the pad cleaning process is terminated by detecting a position of the subsequent substrate to be polished which is undergoing the substrate transferring process.

A workpiece processing apparatus is provided. The apparatus includes a rotary turntable having one or more spindles thereon, the turntable being configured to rotate about a turntable axis. Each of the spindles is configured to receive and secure thereon a workpiece to be processed by the apparatus. Each of the spindles can rotate about their own independent axes. The apparatus includes one or more grind spindles that overlay the turntable and are configured to communicate with the workpieces. The apparatus processes the workpieces by transitioning between first and second operational states. The first operational state centers the spindles and the workpieces thereon under the grind spindle to condition an entire top surface of the workpieces. The second operational state offsets the spindles from the center of the grind spindle to condition a perimeter edge of the workpieces. A controller can govern the transition between first and second operational states.

A wafer grinding system includes a robot arm having a suction board at one end and a table within reach of the robot arm. An upper surface of the table has a vacuum surface for sucking and holding wafers. A pusher coupled to the robot arm extends about the periphery of the suction board. The pusher flattens wafers against the upper surface of the table, allowing the table to hold by suction wafers that would otherwise be too bowed to be held in that way. Additionally, a table can have a vacuum area that is small in comparison to the wafers, which is another way of increasing the magnitude of wafer bow that can be tolerated. A grinding system can use the reduced vacuum area concept to allow the positioning table to hold bowed wafers and the pusher concept to allow the chuck tables to hold bowed wafers.
