Patent ID: 8280852

Claim:
A control method of a processing system that transfers a target object to a processing chamber and applies a predetermined process on the target object in the processing chamber, the control method comprising the steps of: storing predetermined events that have occurred in the processing system in a predetermined log file as log information; overwriting one of the stored log information by new log information when a free area of the predetermined log file is insufficient for storage of the new log information; and collectively backing up the log information stored in the predetermined log file in response to a timing when a specific one of the predetermined events has occurred, wherein the collectively backing up the log information includes backing up the log information stored in the predetermined log file in response to a timing when a predetermined alarm has been generated in the processing system, wherein the predetermined alarm is generated from a programmed alarm sequence included in a portion of a program for controlling processing of the target object in the processing system, and wherein the programmed alarm sequence triggers the predetermined alarm when a processing event associated with the processing of the target object in the processing system occurs that is inconsistent with a configuration of the processing system.
