Carrier storage apparatus, substrate processing apparatus, and carrier transfer method

A substrate processing apparatus, comprising:

• a carrier storage apparatus configured to store a carrier accommodating a plurality of substrates;
• and
• a batch processor provided closer to a positive side of a first horizontal axis than the carrier storage apparatus, and configured to collectively perform processing for the plurality of substrates,
• wherein the carrier storage apparatus comprises:
• a transfer mechanism configured to transfer the carrier;
• a first storage shelf group provided closer to a negative side of the first horizontal axis than the transfer mechanism;
• a second storage shelf group provided closer to the positive side of the first horizontal axis than the transfer mechanism;
• and
• a third storage shelf group provided closer to a positive side or a negative side of a second horizontal axis, which is perpendicular to the first horizontal axis, than the transfer mechanism,
• wherein the first storage shelf group includes a plurality of first storage shelves configured to store the carrier,
• wherein the second storage shelf group includes a plurality of second storage shelves configured to store the carrier,
• wherein the third storage shelf group includes a plurality of third storage shelves configured to store the carrier,
• wherein the plurality of second storage shelves are disposed to be arranged in two or more columns along the second horizontal axis and in two or more stages along a vertical axis,
• wherein the plurality of third storage shelves are disposed to be arranged in two or more stages along the vertical axis, and each of the plurality of third storage shelves is movable along the vertical axis, and
• wherein the transfer mechanism is configured to transfer the carrier to the plurality of first storage shelves, the plurality of second storage shelves, and the plurality of third storage shelves.
