SUBSTRATE TREATING APPARATUS AND SUBSTRATE TRANSFER APPARATUS

A substrate treating apparatus includes a plurality of load ports on which carriers having substrates received therein are placed, a plurality of process chambers that perform processes on the substrates, and a transfer robot that transfers the substrates between the load ports and the process chambers. The transfer robot is movable along a transfer passage having a lengthwise direction formed along a first direction, the load ports and the process chambers are arranged along the first direction on one side and an opposite side of the transfer passage, and the transfer robot transfers the substrates between the carriers placed on the load ports and the process chambers.
