Classification: CPC G | IPC G

Claim 9:
10. A semiconductor apparatus examination apparatus comprising:
a photodetector configured to detect light from a plurality of positions in a semiconductor apparatus and to output a detection signal;
an optical scanner configured to guide light from the plurality of positions to the photodetector; and
a processor configured to perform acquiring a waveform corresponding to each of the plurality of positions based on the detection signal, extracting a waveform corresponding to a specific timing from the waveform corresponding to each of the plurality of positions and generating an image corresponding to the specific timing based on the extracted waveform, and extracting a feature point based on a brightness distribution correlation value in the image corresponding to the specific timing and identifying a position of a drive element in the semiconductor apparatus based on the feature point.
