| description | An inspection system, a lithography apparatus, and an inspection method are provided. The inspection system includes an illumination system, a detection system, and processing circuitry. The illumination system generates a broadband beam and illuminates surface of an object with the broadband illumination beam. The broadband beam has a continuous spectral range. The detection system receives radiation scattered at the surface and by a structure near the surface. The detection system generates a detection signal based on an optical response to the broadband illumination beam. The processing circuitry analyzes the detection signal. The processing circuitry distinguishes between a spurious signal and a signal corresponding to a defect on the surface based on the analyzing The spurious signal is diminished for at least a portion of the continuous spectral range. |
