    摘要: A system method and apparatus to monitor a frictional coefficient of a substrate undergoing polishing is described. A polishing pad assembly includes a polishing layer including a polishing surface, and a substrate contacting member flexibly coupled to the polishing layer having a top surface to contact an exposed surface of a substrate. At least a portion of the top surface is substantially coplanar with the polishing surface. A sensor is provided to measure a lateral displacement of the substrate contacting member. Some embodiments may provide accurate endpoint detection during chemical mechanical polishing to indicate the exposure of an underlying layer.

    摘要: Methods and apparatus to implement techniques for monitoring polishing a substrate. Two or more data points are acquired, where each data point has a value affected by features inside a sensing region of a sensor and corresponds to a relative position of the substrate and the sensor as the sensing region traverses through the substrate. A set of reference points is used to modify the acquired data points. The modification compensates for distortions in the acquired data points caused by the sensing region traversing through the substrate. Based on the modified data points, a local property of the substrate is evaluated to monitor polishing.

    摘要: A system includes a measuring station for positioning an eddy current probe proximate to a substrate in a substrate holder. The probe can produce a time-varying magnetic field, in order to induce eddy currents in one or more conductive regions of a substrate either prior to or subsequent to polishing. The eddy current signals are detected, and may be used to update one or more polishing parameters for a chemical mechanical polishing system. The substrate holder may be located in a number places; for example, in a substrate transfer system, a factory interface module, a cleaner, or in a portion of the chemical mechanical polishing system away from the polishing stations. Additional probes may be used.
