Patent ID: 7908024

Claim:
A system for detecting tool errors to stop a process recipe for a single chamber, comprising: a process tool, further comprising a first chamber and a second chamber, wherein when the first and second chambers process a wafer lot using a process recipe, a process start message is sent; an equipment automation program server, receiving the process start message from the process tool and monitoring and tracking processing states of the process tool; and a fault detection and classification system, receiving the process start message from the equipment automation program server, wherein, when a process error for the first chamber is generated, the process tool transmits the process error to the equipment automation program server; when the process error is retrieved, the equipment automation program server generates an iFDC error command comprising an identification of the first chamber and transmits the iFDC error command to the process tool via the fault detection and classification system and the equipment automation program server; and when the process tool receives the iFDC error command, changing an executing state of the first chamber using an automation program sending a command based on the identification of the first chamber to enable the first chamber to stop performing the process recipe of the first chamber.
