  • Patent number: 11152233
    Abstract: A substrate treating apparatus includes an indexer division, stories, and a controller. Each of the stories includes a first rack, a treating section, and a main transport mechanism. The indexer division includes a carrier rack and a transport device. The transport device performs a feeding operation for transporting substrates from a carrier placed on the carrier rack to the first rack. The transport device further performs an inter-story transporting operation for transporting the substrates between two first racks provided for different stories.
    Type: Grant

  • Patent number: 11152242
    Abstract: A second substrate transportation mechanism is generally set to transport a substrate from a substrate buffer unit to a FOUP placed on an opener. However, if a predetermined condition is satisfied, the second substrate transportation mechanism transports a substrate from the FOUP to the substrate buffer unit. That is, the second substrate transportation mechanism performs an operation different from an ordinary substrate transportation operation. Accordingly, a FOUP transportation mechanism can leave a specific FOUP at a placement position (opener) of the specific FOUP from when all the substrates are taken from the specific FOUP to when all the treated substrates are accommodated in the specific FOUP. Thus, the FOUP transportation mechanism can transport FOUPs except for the specific FOUP so that FOUP transportation efficiency can be enhanced.

  • Patent number: 11101156
    Abstract: A substrate treating apparatus includes the following elements: an indexer block including indexer robots provided for respective carrier receivers and disposed in horizontally fixed positions, each of the indexer robots having arms for taking substrates out of a carrier and loading the substrates into the carrier on the carrier receiver; a bridge block disposed adjacent the indexer block; and a treating block including a plurality of stacked stories each having at least one treating unit. The bridge block includes a buffer, a pass having a plurality of tables covering a range from a bottom story to a top story of the plurality of stories, and two bridge robots each having an arm for transferring the substrates to and from the pass.

  • Patent number: 11075101
    Abstract: Each of first and second substrate transportation mechanisms transports a substrate for a FOUP placed not on, for example, each of two openers disposed laterally but on, for example, each of two openers disposed in an upward/downward direction. Thus, even if the number of openers increases, the substrate is transported not by sliding a hand capable of moving forward and backward, but by lifting, lowering, and rotating the hand. Thus, transportation of the substrate can be simplified. Accordingly, standby time of substrate transportation can be reduced, and a decrease in substrate transportation efficiency can be prevented.
