Abstract
Provided is a method for managing manufacturing apparatuses used in a managed production line including a plurality of manufacturing processes for manufacturing an electronic device, each of the apparatuses being used in one or more of the processes. The method includes acquiring a property of a reference device manufactured in a predetermined reference production line including the manufacturing processes to be performed, performing at least one of the manufacturing processes in the managed production line, performing the other manufacturing processes in the reference production line, and manufacturing a comparison device. The method further includes measuring a property of the comparison device, comparing the measured properties of the reference and the comparison devices, and judging whether a manufacturing apparatus used in the at least one manufacturing process in the managed production line is defective or not, based on a property difference between the reference and the comparison devices.
