  • Patent number: 6676801
    Abstract: A pressure suppression device for a chemical mechanical polishing machine. The chemical mechanical polishing machine includes a polishing table and a polishing head. The polishing table has a polishing pad and a polishing gas input through which a polishing gas is charged. The polishing head holds a wafer and has a wafer gas input through which a wafer gas is charged. The pressure suppression device has a pressure releasing component and a gas input tube coupled to the wafer gas input and the pressure releasing component. When a polishing pressure applied to the polishing pad is smaller than a wafer pressure applied to the wafer, the pressure releasing component releases a part of the wafer pressure until the wafer pressure is smaller than the polishing pressure. As a result, this prevents the wafer slippage or broken wafer that occur when the wafer is blown off from the polishing head by too much wafer pressure.

  • Patent number: 6634455
    Abstract: An acoustic transmission line speaker enclosure with concentric cylindrical structures establishes acoustic coupling between a rear-traveling sound wave and a surrounding air mass. Inherent rigidity or high bending resistance of the cylindrical structure allows use of very thin walled cylinders without a massive and large overall enclosure. According to one aspect of the invention, an outer-most one of said cylinders includes wall structures adapted for coupling the rear-traveling sound wave therethrough to the surrounding air mass in phase with a forward-traveling sound wave from said speaker enclosure. An audio amplifier tunable to a listening room removes very low narrow frequency band components of an audio signal. Listening room cavity resonance is measured by injecting a frequency-varying sound wave into the listening room while detecting peak sound energy within the room. The filter the eliminates from the audio signal frequencies associated with listening room cavity resonance.

  • Patent number: 6352244
    Abstract: 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.
