    摘要: An in-situ method for regenerating a chemical-mechanical polishing pad which includes the steps of: forming the polishing pad by dispensing liquid moldable material, such as wax, polymers or water, on a polishing surface and solidifying the liquid material by reducing the temperature, allowing the moldable material to harden; distributing slurry material on the polishing pad; polishing the surface of a semiconductor wafer with a combination of the slurry material and the polishing pad; and regenerating in-situ the polishing pad. This method quickly, easily and repeatably, resurfaces and refreshes the surface on which the a semiconductor wafer is polished. The polishing pad may also include abrasives embedded therein to enhance its polishing capabilities.

    摘要: The method of polishing metal layers on wafers comprises the steps of: providing indicator areas on said wafer, said indicator areas having combinations of line widths and pattern factors violating existing ground rules of metal lines thereby said indicator areas being dished out during said polishing using a chemical-mechanical polisher to polish the metal layers to remove material therefrom, inspecting indicator areas on the wafer to determine an amount of material removed from said areas, and adjusting the operation of the chemical-mechanical polisher in response to the inspection of the indicator areas. The indicator areas may include macroblocks comprised of a multitude of individual blocks. The wafer may be inspected by optically identifying the polishing state of to blocks in the macroblock. Additionally, the process may be automated for mass production. A feedback loop to the polisher can be formed where data from optical inspection of macroblocks on a polished wafer can be immediately fed back to the polisher in order to adjust process parameters.

    摘要: A method for repairing defects in a surface layer of a substrate. The method comprises the redeposition, in a solvent environment, of a fill material into the defects of the surface layer. The fill material is provided by the surface layer itself or from a separate source comprising a different material from that of the surface layer.

    摘要: A chemical-mechanical polishing (CMP) control system controls distribution of pressure across the backside of a semiconductor wafer being polished. The system includes a CMP apparatus having a carrier for supporting a semiconductor wafer. The carrier includes a plurality of dual function piezoelectric actuators. The actuators sense pressure variations across the semiconductor wafer and are individually controllable. A control is connected to the actuators for monitoring sensed pressure variations and controlling the actuators to provide a controlled pressure distribution across the semiconductor wafer.
