Abstract:
A method for aligning a conveying position of a processing system for processing a processing object, said processing system comprising a processing apparatus which has a supporting table for supporting thereon the processing object and which serves to carry out a predetermined processing for the processing object, an orienter/positioner for detecting an eccentric quantity and eccentric direction of the processing object mounted on a reference table, and at least one transfer mechanism which is provided between the orienter/positioner and the processing apparatus, the method comprising the steps of:detecting an eccentric quantity and eccentric direction of an aligning substate mounted on the reference table and obtaining a position shift quantity of the aligning substrate when the transfer mechanism causes the to-and-fro conveyance of the aligning substrate between the reference table and the supporting table to return the aligning substrate, as a to-and-fro position shift quantity; obtaining a position shift quantity of the aligning substrate when the aligning substrate precisely aligned to be mounted on the supporting table is conveyed to the reference table by the transfer mechanism, as a one-way position shift quantity; and modifying a conveying position of a processing object, which is conveyed toward the supporting table by the transfer mechanism, on the basis of the to-and-fro position shift quantity and the one-way position shift quantity.
