摘要： A method of polishing a substrate includes holding the substrate on a polishing pad with a polishing head, wherein the polishing pad is supported by a platen, creating relative motion between the substrate and the polishing pad to polish a side of the substrate, generating a light beam and directing the light beam towards the substrate to cause the light beam to impinge on the side of the substrate being polished. Light reflected from the substrate is at a detector to generate an interference signal. A measure of uniformity is computed from the interference signal.

摘要： A robust, stand-alone load cell comprises a block of aligned carbon nanotubes with parallel electrodes on opposing sides of the block and an electrical circuit connected between the electrodes for measuring the electrical resistance of the block. The nanotubes are preferably aligned perpendicular to the electrodes. Carbon nanotube-based load cells may be incorporated into a wafer asssembly for characterizing semiconductor processing equipment. Such a wafer assembly includes two parallel wafers with a plurality of carbon nanotube load cells positioned between and attached to both wafers. The load cells are independently electrically connected to a device which monitors and records the resistivity of the load cell. According to further aspects of the invention, each of the load cell's parallel electrodes may be comprised of many small electrodes, where each small electrode on one side of the block has a corresponding small electrode on the opposing side of the block; corresponding pairs of small electrodes are connected in series to form a chain; an electrical circuit, connected to both ends of the chain of opposing pairs of electrodes, is used to measure the electrical resistance of the chain.

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.
