  • Publication number: 20210118710
    Abstract: The present disclosure provides a wafer inspection technology that involves less degradation of the image quality even when an object to be observed has a variation in height due to warpage, etc. of a wafer. This wafer inspection apparatus obtains an image with less degradation by: adjusting the focal point of an observation optical system to a height measured by a height sensor for measuring wafer surface heights; and further, correcting a switching signal for a CCD line sensor on the basis of stage position data and optical magnification data corresponding to the height so as to make a correction corresponding to the wafer surface height.

  • Publication number: 20200340930
    Abstract: It is necessary to guarantee performance by quantitatively evaluating the defect detection sensitivity of an inspection device for using the mirror electron image to detect defect in a semiconductor substrate. The size and position of accidentally formed defects are random, however, and this type of quantitative evaluation has been difficult. This semiconductor substrate 101 for evaluation is for evaluating the defect detection sensitivity of an inspection device and comprises a plurality of first indentations 104 that are formed through the pressing, with a first pressing load, of an indenter having a prescribed hardness and shape into the semiconductor substrate for evaluation. Further, a mirror electron image of the plurality of first indentations of the semiconductor substrate for evaluation is acquired, and the defect detection sensitivity of an inspection device is evaluated through the calculation of the defect detection rate of the plurality of first indentations in the acquired mirror electron image.
