  • Patent number: 11782425
    Abstract: There is provided a configuration that includes: a main controller configured to, when executing a process recipe including a specific step of executing a sub-recipe, control a process controller to execute the sub-recipe a predetermined number of times to perform a predetermined process to a substrate: and a device management controller configured to collect device data during an execution of the process, recipe and store the device data in a storage part. The device management controller is further configured to: search the storage part; acquire the device data in a designated step among respective steps constituting the sub-recipe for a number of times of execution of the sub-recipe; calculate a first standard deviation of the device data acquired for the number of times of execution; and compare the first standard deviation with a threshold value and generate an alarm when the first standard deviation exceeds the threshold value.

  • Publication number: 20230223285
    Abstract: Provided is a technique of processing a substrate by executing a process recipe including a plurality of steps, the technique including: (a) acquiring vibration data of a member that exhausts an atmosphere in a process chamber that processes the substrate from a vibration sensor while executing the process recipe; and (b) detecting presence of an abnormality sign in a case where a ratio between a magnitude of vibration at a rotation frequency of the member and a magnitude of vibration at a comparison frequency that is an integral multiple of the rotation frequency exceeds a preset abnormality sign threshold on the basis of the acquired vibration data.

  • Patent number: 11086304
    Abstract: A substrate processing apparatus includes an operating unit for transmitting apparatus data to a memory, the apparatus data being required while a recipe for processing a substrate is executed; and a data matching unit for comparing the apparatus data stored in the memory. When an error occurs in the substrate processing apparatus, the operating unit transmits data representing the error to the data matching unit. The data matching unit includes: a selection unit for selecting first apparatus data which was acquired when the recipe was executed without an occurrence of the error, and stored in the memory; an acquisition unit for acquiring first and second apparatus data from the memory, the first apparatus data being acquired when an error did not occur and the second apparatus data being acquired when an error occurred; and a calculation unit for comparing the first and second apparatus data and calculating a difference therebetween.
