  Therefore, according to the second embodiment, since the planar space of the substrate lifting / lowering transfer device 53 can be suppressed to less than the plane area of one substrate W, the planar space of the substrate lifting / lowering transfer device 53 is sufficiently reduced, Effective use of factory space can be achieved.

  In addition, this invention is not restricted to description of the above-mentioned embodiment, In addition, it can implement in a various aspect. Further, the scope of rights encompassed by the present invention is not limited to these embodiments.
