A method and apparatus for inspecting a specimen which includes emitting a deep ultraviolet light from a light source illuminating a sample with the deep ultraviolet light through an objective lens, detecting an optical image of the sample by receiving light from the sample by the illumination with a time delay integration sensor through the objective lens, and outputting an image signal, processing the outputted image signal to extract a defect candidate, and determining a defect among the extracted defect candidate using information of a characteristic quality of the extracted defect candidate. In the detection, the time delay integration sensor receives the light from the sample by the illumination through a rear side of the time delay integration sensor.
