Patent ID: 8330948

Claim:
A semiconductor examination apparatus comprising: an energy source device configured to supply a semiconductor substrate with excitation energy to cause luminescence in the semiconductor substrate; an image capturing device configured to capture a first luminescence image of the semiconductor substrate when supplied with a first excitation energy and to capture a second luminescence image of the semiconductor substrate when supplied with a second excitation energy that is different in magnitude from the first excitation energy; a projecting device configured to project a projection energy to be absorbed or reflected at different ratios by a semiconductor area and an area excluding the semiconductor area of the semiconductor substrate where luminescence is not caused; a luminescence image processing device configured to calculate a difference in luminescence intensity between the first luminescence image and the second luminescence image and generate intensity difference image data; a reflection image processing device configured to binarize a reflection image of the semiconductor substrate acquired by the image capturing device as a result of the projection of the projection energy to the semiconductor substrate to create binarized reflection image data; and a detecting device configured to-detect a crack position of a crack occurring in the semiconductor substrate on the basis of the intensity difference image data and the binarized reflection image data.
