Abstract:
An automated and integrated substrate inspecting apparatus for performing an EBR/EEW inspection, a defect inspection of patterns and reticle error inspection of a substrate includes a first stage for supporting a substrate; a first image acquisition unit for acquiring a first image of a peripheral portion of the substrate supported by the first stage; a second stage for supporting the substrate; a second image acquisition unit for acquiring a second image of the substrate supported by the second stage; a transfer robot for transferring the substrate between the first stage and the second stage; and a data processing unit, connected to the first image acquisition unit and the second image acquisition unit, for inspecting results of an edge bead removal process and an edge exposure process performed on the substrate using the first image, and for inspecting for defects of patterns formed on the substrate using the second image.
