    摘要: A method and apparatus for conditioning a polishing pad used in a substrate polishing process. In one embodiment, a method for conditioning a polishing pad utilized to polish a substrate is provided. The method includes providing relative motion between an optical device and a polishing pad having a polishing medium disposed thereon, and scanning a processing surface of the polishing pad with a laser beam to condition the processing surface, wherein the laser beam has a wavelength that is substantially transparent to the polishing medium, but is reactive with the material of the polishing pad.

    摘要: A method for controlling the residue clearing process of a chemical mechanical polishing (“CMP”) process is provided. Dynamic in-situ profile control (“ISPC”) is used to control polishing before residue clearing starts, and then a new polishing recipe is dynamically calculated for the clearing process. Several different methods are disclosed for calculating the clearing recipe. First, in certain implementations when feedback at T0 or T1 methods are used, a post polishing profile and feedback offsets are generated in ISPC software. Based on the polishing profile and feedback generated from ISPC before the start of the clearing process, a flat post profile after clearing is targeted. The estimated time for the clearing step may be based on the previously processed wafers (for example, a moving average of the previous endpoint times). The calculated pressures may be scaled to a lower (or higher) baseline pressure for a more uniform clearing.
