    摘要: A semiconductor device inspection system having an improved measurement accuracy and in operability. A semiconductor device is observed from the bottom surface side. First, image data obtained upon image pickup under infrared illumination is converted into first left-to-right-reversed image data corresponding to a left-to-right-reversed image and the first reversed image data is stored. Then an image is obtained under no illumination from very weak light emitted from an abnormal portion when a bias is applied to the semiconductor device. Image data of the very weak light image is then converted into second left-to-right-reversed image data corresponding to a left-to-right-reversed image. The first and second left-to-right-reversed image data are superimposedly added to each other and a superimposed image is displayed with the abnormal portion being superimposed on a chip pattern as seen from the top surface of the semiconductor device.
