Abstract: In one embodiment, a system (110) to inspect an edge region of a wafer (122), comprises a surface analyzer assembly comprising a radiation targeting assembly that targets a radiation beam onto a surface of the wafer (122); a reflected radiation collection assembly to collect radiation reflected from a surface of the wafer (122); means for rotating the surface analyzer assembly about an edge surface (126) of the wafer (122); and means for detecting one or more defects in the edge region of the wafer.
