Claim Text:
1. A substrate processing system comprising: a transfer chamber which has at least one bi-directional substrate transferring device having a base frame bi-directionally transferring a substrate; and a plurality of processing chambers which apply a semiconductor-manufacturing process to the substrate, wherein the plurality of processing chambers are linearly arranged along two rows confronting each other, and the transfer chamber is between the two rows of the processing chambers, wherein the at least one bi-directional substrate transferring device comprises: a moving unit which is inside the transfer chamber and that moves horizontally, the moving unit including a driving member at an upper surface thereof and first rotating guides at corners of the upper surface of the moving unit, wherein the first rotating guides are connected to second rotating guides at corners of the base frame corresponding to the corners of the moving unit; a bi-directional substrate transferring unit which is in the moving unit, and transfers the substrate to the processing chamber through a bi-directional sliding movement, and transfers the substrate to the processing chamber through a bi-directional sliding movement; and a rotating unit having a rotation member and a housing therein, wherein the rotating unit is between the moving unit, the bi-directional substrate transferring unit, and the first and second rotating guides, and is configured to rotate the second rotating guides of the base frame at a predetermined angle by linearly moving the housing by rotation of the rotation member according to the driving member, wherein the second rotating guides follow the first rotating guides.
