Claim Text:
1. A substrate processing system comprising: a first transfer apparatus configured to unload substrates from a cassette that accommodates the substrates and configured to transfer the unloaded substrates in a transfer direction; at least one first accommodating unit configured to accommodate the substrates transferred by the first transfer apparatus; multiple first substrate processing units, which are divided into at least two groups and arranged in a height direction, configured to perform a preset process to the respective substrates; multiple second accommodating units, which each respectively corresponds to one of the groups and are arranged to be parallel with the at least one first accommodating unit in the height direction, configured to accommodate the substrates; multiple second transfer apparatuses, each respectively corresponding to one of the groups, configured to unload the substrates from the second accommodating units corresponding to the same groups and transfer the substrates into the first substrate processing units belonging to the same groups; multiple second substrate processing units, which each respectively corresponds to one of the groups and are arranged to be disposed above and below the at least one first accommodating unit and the second accommodating units in the height direction, configured to perform a predetermined process to the respective substrates; and at least one delivery apparatus configured to deliver the substrates between the at least one first accommodating unit and the second accommodating units and configured to transfer the substrates between the at least one first accommodating unit and the second substrate processing units, wherein the at least one first accommodating unit corresponding to two adjacent groups is arranged at a middle height position between the two groups, and the second accommodating units respectively corresponding to the groups are arranged above and below the at least one first accommodating unit, respectively, the at least one delivery apparatus is plural in number, and the delivery apparatuses respectively correspond to the groups, and the delivery apparatuses deliver the substrates accommodated in the at least one first accommodating unit to the second accommodating units corresponding to the same groups, respectively, wherein the delivery apparatuses deliver the substrates only perpendicular to the transfer direction.
