  • Publication number: 20220136497
    Abstract: There is provided a technique that includes: a controller configured to execute a process recipe including a plurality of steps to perform a predetermined process on a substrate. The controller acquires device data, which includes at least one of a current value, a rotational speed, and a back pressure of a pump, in a specific step among the plurality of steps and compares an acquired value of the device data with a previously acquired value of the device data. The controller generates a notification if at least one of the following conditions is met: the acquired value for the current value is larger than the previously acquired value for the current value, the acquired value for the back pressure is larger than the previously acquired value for the back pressure, and the acquired value for the rotational speed is smaller than the previously acquired value for the rotational speed.
