摘要： A method of determining a physical property of a substrate includes recording a first spectrum obtained from a substrate, the first spectrum being obtained during a polishing process that alters a physical property of the substrate. The method includes identifying, in a database, at least one of several previously recorded spectra that is similar to the recorded first spectrum. Each of the spectra in the database has a physical property value associated therewith. The method includes generating a signal indicating that a first value of the physical property is associated with the first spectrum, the first value being determined using the physical property value associated with the identified previously recorded spectrum in the database. A system for determining a physical property of a substrate includes a polishing machine, an endpoint determining module, and a database.

摘要： Methods for polishing tungsten are provided. During ECMP, increasing the voltage to the pad is not always enough to increase the polishing rate. When polishing tungsten, simply increasing the applied voltage will, in some cases, actually decrease the removal rate. By increasing the down force pressure between the polishing pad and the substrate, the applied voltage, and the rotation speed of the substrate and the polishing pad, the tungsten removal rate will also increase.

摘要： Systems and methods for performing one or more measurements of a substrate at one or more radii along the substrate are described. Thickness measurements taken at various radii along the substrate can be averaged together to obtain an average value that reflects an overall substrate thickness. A more accurate measurement of the overall substrate thickness can be obtained by performing multiple measurements and averaging the measurements together. Using the average value, polishing can be adjusted to ensure that the substrate achieves a desired planarized thickness profile.

摘要： A method of controlling polishing includes polishing a first substrate having an overlying layer on an underlying layer or layer structure. During polishing, the substrate is monitored with an in-situ monitoring system to generate a sequence of measurements. The measurements are sorted into groups, each group associated with a different zone of a plurality of zones on the substrate. For each zone, a time at which the overlying layer is cleared is determined based on the measurements from the associated group. At least one second adjusted polishing pressure for at least zone is calculated based on a pressure applied in the at least one zone during polishing the substrate, the time for the at least one zone, and the time for another zone. A second substrate is polished using the at least one adjusted polishing pressure.
