Abstract:
1. A substrate processing apparatus for use in a process of mounting electronic components onto an outer edge portion of a substrate, said apparatus comprising: a suction stage including (i) suction portions for sucking an undersurface of the outer edge portion of the substrate, and (ii) a flat portion for correcting warping at the undersurface of the outer edge portion of the substrate; vacuum paths connected to said suction stage; a vacuum-suction unit operable to vacuum-suck the outer edge portion of the substrate to be placed on said suction stage using said suction portions, said vacuum-suction unit being connected to at least one of said vacuum paths; a substrate transportation unit operable to hold and move the substrate, and to place the outer edge portion of the substrate on said suction stage; a hollow portion for connecting said vacuum paths and said suction portions, said hollow portion being formed inside said suction stage; an opening and closing unit operable to open and close said hollow portion; and a backup stage that is a placement stage for supporting the undersurface of the outer edge portion of the substrate, wherein the longitudinal length of said suction stage is the same as the longitudinal length of said backup stage.
