  • Publication number: 20110177623
    Abstract: An arrangement and method for managing the tribology associated with a chemical mechanical planarization (CMP) process continuously monitors and modifies the properties of a polishing slurry in order to assist in controlling the removal rate associated with the CMP process. The viscosity of slurry as it leaves the CMP system (“spent slurry”) and the material removal rate associated with the semiconductor wafer are measured, and then the viscosity of the incoming slurry is adjusted if the measured material removal rate differs from a desired removal rate. If the removal rate is considered to be too fast, the viscosity of the fresh slurry being dispensed onto polishing pad is decreased; alternatively, if the removal rate is too slow, the viscosity is increased. As an alternative to modifying the viscosity of the slurry (or, perhaps in addition to modifying the viscosity), a lubricant may be added to the slurry to slow down the removal rate.

  • Patent number: 7922823
    Abstract: Compositions useful in microelectronic device manufacturing for surface preparation and/or cleaning of wafer substrates such as microelectronic device precursor structures. The compositions can be employed for processing of wafers that have, or are intended to be further processed to include, copper metallization, e.g., in operations such as surface preparation, pre-plating cleaning, post-etching cleaning, and post-chemical mechanical polishing cleaning of microelectronic device wafers. The compositions contain (i) alkanolamine, (ii) quaternary ammonium hydroxide and (iii) a complexing agent, and are storage-stable, as well as non-darkening and degradation-resistant in exposure to oxygen.

  • Publication number: 20110039485
    Abstract: The evacuation properties of an abrasive disk are improved by forming its apertures to exhibit a configuration that will direct process fluids onto or away from a workpiece (or contact) interface through capillary action, surface tension/affinity, and/or boundary layer pump actions. The capillary action is accomplished by modifying the geometries of the apertures to form capillary tubes, where the orientation and lift angle of the capillary tubes is controlled to improve the flow of relatively thin layers of liquids. The surface tension/affinity between a liquid material and the abrasive disk is controlled by modifying the through-hole apertures to exhibit a serrated inner surface, which will decrease the attraction between the material of the abrasive disk and the process liquid.

  • Publication number: 20110015108
    Abstract: The invention relates to aqueous, buffered, fluoride containing compositions having a pH of greater than 7.0 to about 11.0. In certain embodiments, the buffered compositions have an extended worklife because pH dependent attributes such as oxide and metal etch rates are stable so long as the pH remains stable.

  • Publication number: 20090287340
    Abstract: An apparatus and method for collecting and analyzing the effluent stream created by a chemical mechanical planarization (CMP) process performs a continuous measurement of at least one effluent characteristic and integrates the results over time to create a volumetric analysis of the planarization process. The volumetric analysis can be used as feedback/feedforward signals to control the planarization process itself (e.g., endpoint detection based upon an known initial thickness of film material), create alarm signals for out-of-range measurements, and/or waste stream indicators useful in treating the effluent prior to discharge (e.g., determining a pH correction).
