    摘要： A method and system for intercepting and forwarding High-Speed SECS Message Services (HSMS) communication between at least two entities, includes a fail-safe bypass to ensure the communications link between the entities is not severed upon failure of the intercepting/forwarding agent. A “pass-through” agent is placed in between two entities communicating via an HSMS link, such that the pass-through agent is able to intercept messages from one entity and forward it to the other entity, and vice versa. The pass-through agent is able to see all messages between the two entities, and is also able to create HSMS messages and send them to one of the entities as if the message had come from the other entity, thereby conferring the ability to inject additional HSMS messages. Should the pass-through agent fail, a bypass mechanism ensures that the two entities can automatically resume HSMS communication without the pass-through agent.

    摘要： Leaks in a processing chamber, including “virtual leaks” resulting from outgassing of material present within the chamber, may be detected utilizing an optical emission spectroscopy (OES) sensor configured to monitor light emitted from plasma of a sample from the chamber. According to certain embodiments, gas introduced into the chamber by the leak may be detected directly on the basis of its optical spectrum. Alternatively, gas introduced by the leak may be detected indirectly, based upon an optical spectrum of a material resulting from reaction of the gas attributable to the leak. According to one embodiment, data from the OES sensor is received by a processor that is configured to compute a leak detection index. The value of the leak detection index is compared against a threshold to determine if a leak is detected. If the value of the index crosses the threshold, a notification of the existence of a leak is sent.
