  • Patent number: 10541163
    Abstract: A technique to prevent reduction in throughput of a substrate processing apparatus. On the occurrence of an event disabling execution of a recipe by a processing unit, a different recipe executed by this processing unit may be used depending on the type of event having occurred. The type of event to occur and a substitute recipe that can take the place of a recipe being executed are associated in advance. On the occurrence of abnormality, it is determined whether or not a recipe being executed can be substituted by a different recipe. If the recipe can be substituted, it is determined whether or not the substitute recipe is contained in an unfinished job. If these conditions are satisfied, a substrate processing schedule is changed to execute the substitute recipe in this processing unit. If these conditions are not satisfied, substrate process in this processing unit is stopped.

  • Publication number: 20200021282
    Abstract: A gate drive circuit includes a driver for driving a gate of a switching element, a peak voltage detector, and a drive capacity calculator. The peak voltage detector detects a peak voltage at a main terminal of the switching element when the switching element is OFF. The drive capacity calculator calculates a voltage difference value between the detected peak voltage and an allowable voltage value at the main terminal of the switching element, where the allowable voltage is based on the specifications of the switching element. The drive capacity calculator changes a drive capacity of the driver to gradually decrease the difference between the detected peak voltage and the allowable voltage.
