    摘要: The invention provides a chemical-mechanical polishing pad, which includes a plurality of annular grooves and a plurality of streamline grooves designed according to principles of the hydrodynamics. The streamline grooves of polishing pad are designed according to flow equations derived from source flow and vortex flow, and the streamline grooves of polishing pad uniformly distribute the slurry on the polishing pad. An angle and a depth of the streamline groove, which are calculated by boundary layer effect of the streamline groove function, are used to design an optimum structure for polishing pad.

    摘要: A method for increasing the working life of retaining rings in a chemical-mechanical polishing machine. The method includes adding an extra pad between a retaining ring and a carrier so that the retaining ring is prevented from slippage and pressure on wafer can be evenly spread over the polishing pad of a polishing machine. Therefore, the rate at which a retaining ring wears out in chemical-mechanical polishing operation can be greatly reduced, and the working life of a retaining ring can be doubled.

    摘要: A filtering device used to filter the slurry is disclosed, including a crossflow fan within the filter housing, and a driving mechanism relative to the crossflow fan under the filter housing to drive the crossflow fan spinning to agitate the slurry in the filter housing, so as to prevent the particles in the slurry from adhering to the surface of the filter. The filtering device further includes a spoiler between the crossflow fan and the filter, so that larger particles remain circulating somewhere between the tip of the spoiler and the crossflow fan, instead of flowing to the filter, to prolong the lifetime of the filter.

    摘要: An auxiliary gasline-heating unit is used in a chemical vapor deposition apparatus. The auxiliary gasline-heating unit serves to increase the exit temperature of the mixture of N2 gas and He-dilute gas in order to prevent TDMAT, Ti[N(CH3)2]4, from being condensed and becoming a gasline contaminant when the mixture mixes with the TDMAT and a carrier gas.
