  • Patent number: 11948823
    Abstract: A substrate treating apparatus includes a carrier platform, a transport mechanism, and a controller. The carrier platform places a carrier thereon. The carrier includes a plurality of shelves arranged in an up-down direction. The shelves are each configured to place one substrate thereon in a horizontal posture. The transport mechanism is configured to transport a substrate to a carrier placed on the carrier platform. The controller controls the transport mechanism. The transport mechanism includes a hand and a hand driving unit. The hand supports a substrate. The hand driving unit moves the hand. The controller changes a height position of the hand when the hand is inserted between two of the shelves adjacent to each other in the up-down direction, depending on a shape of a substrate taken from or placed on one of the shelves by the transport mechanism.
