| 摘要 |
Embodiments of the present invention generally provide apparatus and methods for preventing contamination within a processing system due to substrate breakage. In one embodiment, an acoustic detection mechanism is disposed on or within a process chamber to monitor conditions within the process chamber. In one embodiment, the acoustic detection mechanism detects conditions indicative of substrate breakage within the process chamber. In one embodiment, the acoustic detection mechanism detects conditions that are known to lead to substrate breakage within the process chamber. In one embodiment, the acoustic detection mechanism is combined with an optical detection mechanism. By early detection of substrate breakage or conditions known to lead to substrate breakage, the process chamber may be taken off line and repaired prior to contamination of the entire process system.
