  • Patent number: 7922791
    Abstract: The present invention provides a filtering system for a semiconductor processing tool. In one embodiment, the filtering system is associated with the semiconductor processing tool. A system of the invention comprises a first and second filter layer in fluid communication with a gas flow path. The flow path is a gas stream comprising volatile silica containing compounds such as hexamethyldisiloxane and trimethylsilanol. The gas flow path passes through the first and second filter layer to fluidly communicate with the semiconductor processing tool. Preferably, the first filter layer of the filtering system is upstream along the gas flow path from the second filter layer. The medias of the first and second filter layers are selected and arranged based on given contaminant concentrations.

  • Patent number: 7540901
    Abstract: A filter includes at least two different adsorptive media. First, chemisorptive media, which is porous and includes an acidic functional group, is used to remove molecular bases, including ammonia, organic amines, imides and aminoalchols, from the atmosphere used in semiconductor fabrication and other processes that require uncontaminated gaseous environments of high quality. Second, physisorptive media is able to adsorb condensable contaminants, particularly those having a boiling point greater than 150 degrees C. The physisorptive media can include untreated, activated carbon.

  • Patent number: 7430893
    Abstract: The present invention relates to a system and method for sampling a gas flow to measure one or more contaminants within a semiconductor processing tool. The system includes a portable unit containing one or more dry traps, Tenax traps and, if desired, wet impingers. The unit is coupled to a gas flow in a clean room and the dry traps. Tenax traps and wet impingers measure contaminants contained in the gas supply for a determined sampling interval. When the sampling interval is done, the unit is sent to an analysis facility for processing.

  • Publication number: 20060108221
    Abstract: A method and apparatus for improving measurement accuracy in a gas monitoring system is provided. The apparatus can be connected to a plurality of gas sample lines each containing a gas sample. The gas samples are routed through a number of delivery channels which are fewer in number than the plurality of sample lines. Each delivery channel is alternatively coupled to a detector which identifies contaminants present in the gas samples. Each delivery channel includes a voltage sensitive orifice (VSO). The VSO's are operated by a controller and provide gas samples at a constant flow and a constant pressure to the detector independent of the length of the gas sample line being measured.
