摘要:
Methods for chemical mechanical polishing (CMP) of semiconductor substrates, and more particularly to temperature control during such chemical mechanical polishing are provided. In one aspect, the method comprises polishing the substrate with a polishing surface during a polishing process to remove a portion of the conductive material, repeatedly monitoring a temperature of the polishing surface during the polishing process, and exposing the polishing surface to a rate quench process in response to the monitored temperature so as to achieve a target value for the monitored temperature during the polishing process.
