    摘要: A beam emitted from a first light source is shed on the surface of a rotating wafer to form a beam spot. Scattered light arising from foreign matter and other defects on the surface of the wafer is detected in a plurality of directions and output in the form of a signal. Vertical movement of the wafer surface is detected by using white light or broadband light from a second light source. The position of the beam spot on the wafer surface is corrected in accordance with the information on the detected vertical movement for the purpose of minimizing a coordinate error that may arise from the vertical movement of the wafer surface. Further, the emission direction and emission position of light generated from the first light source are corrected to minimize a coordinate error that may arise from variations of the first light source. These corrections are made to enhance the accuracy of the coordinates of detected foreign matter and other defects. Moreover, the illumination beam spot diameter is corrected to prevent the detection sensitivity and foreign matter coordinate detection error from varying from one apparatus to another.
