Abstract:
1. An automatic wafer storage system for a transport system of a semi-conductor factory, the transport system including at least one belt and at least one transport tool, the transport tool being configured to move on the belt in one direction and transport wafers to an idle equipment for processing, the automatic wafer storage system comprising: an analysis module electrically connected to the transport system and the idle equipment configured to estimate locations of the transport tool and the idle equipment and send out a transport order indicating a predetermined location; and at least one storage unit for storing the wafers movably disposed on the belt and in electrical connection with the analysis module configured to receive the transport order and moves to the predetermined location, wherein the storage unit moves back to an original location automatically when completing the transport order to wait for a next transport order, wherein the transport tool also moves to the predetermined location and carries the wafers to the idle equipment for processing.
