    摘要: A processing apparatus includes a chuck table that holds a workpiece by a holding face, a processing unit that processes the workpiece with a grinding whetstone or a polishing pad, a movement unit for moving the chuck table and the processing unit parallel to the holding face, a processing feeding unit for moving the chuck table and the processing unit in a direction orthogonal to the holding face, an inspection unit to inspect a process mark of the workpiece during processing, a dressing unit to dress the grinding whetstone or the polishing pad of the processing unit, and a control unit. When a process mark of a size exceeding a threshold value is detected on the process face of the workpiece, the control unit stops processing of the workpiece, and after the grinding whetstone or the polishing pad is dressed, restarts processing.

    摘要: A method of conditioning a CMP polishing pad to attain a desired thickness profile in a polished layer on a wafer is disclosed. The incoming thickness profile of the layer to be polished, the thickness profile of the polishing pad, a polish rate of layer as a function of pressure and the removal rate of polishing pad material by a conditioning block are used to compute a sweep pattern for the conditioning block which will produce a desired thickness profile on the polishing pad. The method may be applied to maintaining the desired profile on the polishing pad during the course of polishing multiple wafers. The pad profile may be adjusted to keep pressure between the pad and the wafer to a safe limit to reduce polishing defects.
