Patent ID: 7493904

Claim:
A liquid processing method for transferring a plurality of sets of substrates, which are respectively housed in a plurality of carriers placed on an a delivery section, onto one holder placed at an interface section, and then applying predetermined liquid processing to the sets of substrates held on the holder in a liquid processing section, the method comprising: respectively placing the carriers at an inspection position of the delivery section and performing an inspection of the number and/or housed state of the set of substrates housed in each carrier; transferring a carrier with the set of substrates housed herein from the inspection position to a carrier stock section of the delivery section and storing the carrier in the carrier stock section, where the carrier is judged by the inspection that the liquid processing is applicable to the set of substrates housed therein; determining cancellation of liquid processing to all the sets of substrates housed in the carriers and preventing the sets of substrates from being transferred to the interface section, where one of the carriers is judged by the inspection that the liquid processing is not applicable to the set of substrates housed therein; respectively placing the carriers at a pickup position of the delivery section and transferring the sets of substrates from the carriers onto the holder in the interface section, after all the carriers are judged by the inspection that the liquid processing is applicable to the sets of substrates housed therein; and applying the liquid processing to the sets of substrates held on the holder in the liquid processing section.
