  • Publication number: 20120065763
    Abstract: Provided are a substrate processing apparatus, a display method thereof, and a substrate processing system capable of detecting any change in the condition of each component of a substrate processing apparatus. In the substrate processing system including the substrate processing apparatus for processing a substrate and a group management apparatus connected thereto, the substrate processing apparatus is configured to acquire monitor data representing at least the condition of each component of the substrate processing apparatus, aggregate a plurality of the monitor data to generate package data including at least one of a maximum value, an average value, and a minimum value of the monitor data, and transmit the package data to the group management apparatus. The group management apparatus is configured to receive the package data from the substrate processing apparatus and readably store the same therein.

  • Publication number: 20110079177
    Abstract: A maintenance engineer can analyze an abnormal state with less difficulty in a rapid and correct manner independent of his/her skill. A substrate processing system comprises: a substrate processing apparatus configured to operate according to a recipe defining a process sequence and process conditions, and a group managing apparatus connected to the substrate processing apparatus. The group managing apparatus comprises an analysis support unit. The analysis support unit is configured to extract check item information relating to both abnormal state information for identifying an abnormal state occurring when the recipe is executed and apparatus type information for identifying the type of the substrate processing apparatus at which the abnormal state occurs, and to prepare a check item table comprising the extracted check item information.
