    摘要: An apparatus and method for reducing hazardous gases exhausted from a process chamber 25 includes an effluent plasma reactor 210 and a downstream catalytic reactor 220. The reactor 210 may include a consumable liner that reacts with the energized effluent to remove the hazardous gases. The catalytic reactor 220 may also include catalytic surfaces 227 in a honeycomb, foam, or pellet structure 225 to catalyze reactions that further reduce hazardous gas content.

    摘要: An effluent abatement system 200 that may be used to abate F2 gas content of effluent exhausted from a process chamber 35, such as effluent from a CVD chamber cleaning process includes a catalytic reactor 250 to reduce the content of F2 in the effluent 100. The system may further include a prescrubber 230 to add reactive gases to the effluent 100 and/or to treat the effluent 100 prior to treatment in the catalytic reactor 250. Alternatively reactive gases can be added to the effluent 100 by a gas source 220.

    摘要: Endpoint of a chemical mechanical polishing process is detected by monitoring acoustical emissions produced by contact between a polishing pad and a wafer. The acoustic information is resolved into a frequency spectrum utilizing techniques such as fast Fourier transformation. Characteristic changes in frequency spectra of the acoustic emissions reveal transition in polishing between different material layers. CMP endpoint indicated by a change in the acoustic frequency spectrum is validated by correlation with other sensed properties, including but not limited to time-based changes in amplitude of acoustic emissions, frictional coefficient, capacitance, and/or resistance. CMP endpoint revealed by a change in acoustic frequency spectrum can also be validated by comparison with characteristic frequency spectra obtained at endpoints or polishing transitions of prior operational runs.
