    摘要: When irradiating a sample with light from a light source through an object lens, discretely changing a relative position between a beam condensing position of the object lens and the sample in an optical axis direction of the converging beam, obtaining light intensity information from the sample at each relative position, extracting plural pieces of light intensity information from a light intensity information group, estimating a maximum value on a change curve adaptive to the plural pieces of extracted light intensity information and the relative position for the maximum value, and obtaining the estimated maximum value of the light intensity information and relative position as brightness information and height information, these information about the sample can be continuously obtained by discretely performing an iterative operation on the relative position between a beam condensing position of the object lens and the sample in an optical axis direction of the converging beam.

    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.
