  • Patent number: 11037808
    Abstract: During a teaching operation regarding a transport mechanism, a hand of the transport mechanism is moved to a tentative target position in a substrate supporter, and a substrate supported at a reference position in the substrate supporter is received by the hand. A positional relationship between the substrate held by the hand and the hand is detected. A deviation between the tentative target position and the reference position is acquired as correction information based on the detected positional relationship. During the teaching operation or during substrate processing, the tentative target position is corrected to a true target position to coincide with the reference position based on the acquired correction information. During the substrate processing, the hand is moved to the true target position, so that the substrate is transferred to the substrate supporter by the hand, or the substrate is received from the substrate supporter by the hand.

  • Publication number: 20210159293
    Abstract: Disclosed are a substrate treating apparatus and a substrate transporting method. A first treating block includes a developing-treatment layer and an interface layer arranged in an up-down direction. Accordingly, the interface layer is couplable with the indexer block. Moreover, a substrate transport mechanism of the indexer block transports a substrate from one of buffer units located at a predetermined height position in a substrate buffer to another of the buffer units located at a different height position in the substrate buffer. Accordingly, the interface layer is accessible to the buffer unit located at a height position corresponding to the interface layer. Thus, the interface layer can be made compact. Moreover, the interface layer is located in the upper part or the lower part of the developing-treatment layer, leading to reduction in footprint.

  • Publication number: 20210090918
    Abstract: A substrate carrier apparatus includes a hand, an advancing/retracting mechanism, an elevation mechanism, a movement mechanism, and a detector. The advancing/retracting mechanism moves the hand in a forward and backward direction to cause the hand to enter and be retracted from a substrate container. The elevation mechanism elevates the hand so that the hand lifts a substrate from below. The movement mechanism moves the hand to a position facing the substrate container. The detector detects a position of the substrate in the forward and backward direction in an entry state where the advancing/retracting mechanism causes the hand to enter the substrate container, moves integrally with the hand, and is disposed at a position adjacent to the substrate in a measurement direction intersecting with the forward and backward direction.

  • Publication number: 20210061587
    Abstract: Disclosed is a substrate treating system and a substrate transporting method. A substrate transport mechanism of an indexer block can take a substrate W into and out of a carrier placed on a platform. Moreover, the substrate transport mechanism transports the substrate W between two treatment layers at different height positions in a first treating block and a second treating block. Accordingly, any delivery block configured to move substrates between two treatment layers in an up-down direction is not necessarily provided between the indexer block and the treating block as in the prior art. This achieves suppression of a footprint of the substrate treating system.

  • Publication number: 20210020475
    Abstract: Disclosed are a substrate treating apparatus and a substrate transporting method for the substrate treating apparatus. Two treating blocks are arranged so as not to be stacked, and a first treating block, an ID block, and a second treating block are linearly connected horizontally. Accordingly, the number of treatment layers is increasable while a height of the substrate treating apparatus is suppressed. The first and second treating blocks are each connected to the ID block directly. This enables suppression in step of passing a substrate through a treating block without performing any treatment on the substrate, leading to prevention of decrease in throughput. In addition, a substrate buffer is placed in the middle of the two treating blocks. The two treating blocks enable transportation of substrates W with the substrate buffer. Thus, reduction in footprint of the substrate treating apparatus is obtainable.

  • Publication number: 20210020473
    Abstract: Disclosed is a substrate treating system and a substrate transporting method. For instance, it is assumed that an indexer block, a first treating block, and a second treating block are arranged in this order. In this case, for transporting a substrate treated in the second treating block to an indexer block, the substrate is necessarily sent through the first treating block without any treatment in the first treating block. However, the first treating block and the second treating block are both connected to the indexer block. Therefore, transportation of the substrate is performable directly from the second treating block to the indexer block without through the first treating block. Therefore, reduction in throughput is suppressible.

  • Patent number: 10727087
    Abstract: Disclosed is a substrate transporting device including a transport mechanism, a transport chamber, a first exhaust fan, and a controller. The transport mechanism is movable in parallel in a given direction. The transport chamber includes a first wall disposed on a first side of the given direction of the transport mechanism, and a plurality of transportation ports each used for moving the substrate between an exterior and an interior of the transport chamber. The first exhaust fan is disposed closer to the first wall than any of the transportation ports, and exhausts gas in the transport chamber outside the transport chamber. The controller performs control such that, when the transport mechanism moves toward the first wall in a first proximal area whose distance from the first wall is of a given value or less, an exhaust amount of the first exhaust fan is larger than that when the transport mechanism moves toward the first wall out of the first proximal area.

  • Publication number: 20200211881
    Abstract: Disclosed is a substrate treating apparatus, a carrier transporting method, and a carrier buffer device. A carrier transport mechanism transports a carrier between platforms of two openers and carrier storage shelves. The carrier storage shelves and the carrier transport mechanism are each mounted on a first treating block. Accordingly, there is no need as before to provide the carrier storage shelves and the carrier transport mechanism horizontally in an extended manner from the indexer block, achieving reduction in installation area extending horizontally. In other words, reduction in footprint of a substrate treating apparatus is obtainable.

  • Publication number: 20200211880
    Abstract: Disclosed are a substrate treating apparatus and a substrate transporting method. A platform is placed on a first ID block, and a platform is placed on a second ID block. A currently-used carrier platform is provided only on the first ID block. Accordingly, a substrate is transported in both a forward path and a return path between the first ID block and an IF block. According to the disclosure, the substrate is sent in the return path from the IF block to the second ID block disposed between a coating block and a developing block without being transported from the IF block to the first ID block. Consequently, transportation process in the return path by the coating block disposed between the first ID block and the second ID block is reduced. As a result, an entire throughput of a substrate treating apparatus can be enhanced.

  • Publication number: 20200211882
    Abstract: Disclosed are a substrate treating apparatus and a substrate transporting method. A first ID block takes a substrate from a carrier placed on a carrier platform and sends the taken substrate to one of six treatment layers. Moreover, a second ID block returns the substrate, sent from the treatment layer, for example, to a carrier placed on a platform. This allows the first ID block to transport many substrates to the six treatment layers arranged in an upward/downward direction more rapidly. Moreover, this simultaneously allows the second ID block to transport many substrates, having been sent from the six treatment layers arranged in the upward/downward direction, to the carrier more rapidly. As a result, a throughput of a substrate treating apparatus can be enhanced.

  • Publication number: 20200211868
    Abstract: Disclosed is a substrate treating apparatus and a substrate transporting method. An ID block 2, a coating block 3, a developing block 4, and an IF block 6 are arranged in this order. A platform 13 is placed on the ID block 2, and a platform 47 is placed on the IF block 6. A currently-used carrier platform is provided only on an ID block. Accordingly, a substrate is transported in both a forward path and a return path between the ID block and the IF block. According to the disclosure, a substrate W is transported from the IF block 6 to the developing block 4 in the return path, and thereafter, the substrate W is returned back from the developing block 4 to the IF block 6 without being transported to the coating block 3. Consequently, transportation process by the coating block 3 in the return path is reduced so that an entire throughput of a substrate treating apparatus 1 can be enhanced.

  • Publication number: 20200098612
    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.

  • Publication number: 20200098611
    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.
