    Abstract: Systems configured to inspect a wafer are provided. One system includes an illumination subsystem configured to illuminate an area on the wafer by directing light to the wafer at an oblique angle of incidence. The system also includes a collection subsystem configured to simultaneously collect light scattered from different spots within the illuminated area and to focus the light collected from the different spots to corresponding positions in an image plane. In addition, the system includes a detection subsystem configured to separately detect the light focused to the corresponding positions in the image plane and to separately generate output responsive to the light focused to the corresponding positions in the image plane. The output can be used to detect defects on the wafer.

    Abstract: Computer-implemented methods for inspecting and/or classifying a wafer are provided. One computer-implemented includes detecting defects on a wafer using one or more defect detection parameters, which are determined based on a non-spatially localized characteristic of the wafer that is determined using output responsive to light scattered from the wafer generated by an inspection system. Another computer-implemented method includes classifying a wafer based on a combination of a non-spatially localized characteristic of the wafer determined using output responsive to light scattered from the wafer generated by an inspection system and a spatially localized characteristic of the wafer determined using the output.
