  • Patent number: 7027638
    Abstract: A method for correcting color variations on the surface of a wafer, a method for selectively detecting a defect from different patterns, and computer readable recording media for the same are provided. Color variations in images of different parts of a wafer can be corrected using the mean and standard deviation of grey level values for the pixels forming each of the different parts of the wafer. In addition, different threshold values are applied to metal interconnect patterns and spaces of the wafer so that a defect can be selectively detected from the different patterns. Thus, a bridge known as a fatal, or killing defect to a semiconductor device can be detected without also falsely detecting grains as fatal defects. Due to increased defect screening capacity of the methods, the defect detecting method can be further efficiently managed.

  • Patent number: 6870948
    Abstract: A method and apparatus for numerically analyzing a growth degree of grains grown on a surface of a semiconductor wafer, in which the growth degree of grains is automatically calculated and numerated through a computer by using an image file of the surface of the semiconductor wafer scanned by an SEM. A predetermined portion of a surface of the wafer is scanned using the SEM, and the scanned SEM image is simultaneously stored into a database. An automatic numerical program applies meshes to an analysis screen frame and selects an analysis area on a measured image. Thereafter, a smoothing process for reducing an influence of noise is performed on respective pixels designated by the meshes using an average value of image data of adjacent pixels. A standardization process is then performed, based on respective images in order to remove a brightness difference between the measured images.

  • Patent number: 6528333
    Abstract: A method and device detect for the presence of defects, namely micro-scratches, in the surface of a wafer. Light is projected onto a medium at the surface of the wafer, at an angle at which light is not reflected by another layer that may be located under the medium. Light reflected by the surface of the wafer is converted into an electrical signal but any light scattered by the surface is excluded as much as possible from contributing to the formation of the signal. The electric signal corresponds to the intensity of the light reflected from the surface of the wafer. As the light is scanned across the wafer, the values of the electric signal are compared to yield a determination of whether defects are present in the medium. Because the light projected onto the surface of the wafer will be scattered by defects such as micro-scratches, the wafer can be successfully monitored for the existence of such micro-scratches.

  • Patent number: 6440760
    Abstract: Embodiments of the present invention include methods for measuring a semiconductor wafer which has been subjected to an etching process. Light is radiated at the semiconductor wafer. Light within a selected wavelength band reflected from the semiconductor wafer is measured to provide an output value. A ratio of the output value and a reference value is determined. The reference value may be based on light within the selected wavelength band reflected from a reference surface, such as a bare silicon reference surface. It is determined that the semiconductor wafer is under-etched if the determined ratio does not meet the reference value. A normalized optical impedance or a polarization ratio may be measured based on light within a selected wave length band reflected from the semiconductor wafer to provide the output value in various embodiments of the present invention.
