    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. After comparing standardized image data values of the respective pixels with a predetermined threshold value, the number of pixels whose standardized image data value is greater than the threshold value is counted. The growth degree of grains on the surface of the wafer is calculated by numerating a ratio of the counted number with respect to a total number of the pixels contained within the analysis target image.

    Abstract: Scanning Electron Microscope (SEM) analysis is used to detect undesired conductive material on the gate sidewall spacers. The undesired conductive material is then etched from the sidewall spacers if the undesired material is detected by the SEM analysis. More specifically, integrated circuit field effect transistors may be manufactured by forming on an integrated circuit substrate, a plurality of field effect transistors, each comprising spaced apart source and drain regions, a gate therebetween including a sidewall, a sidewall spacer on the sidewall and contacts comprising conductive material on the source and drain regions. At least one of the field effect transistors may include undesired conductive material on the sidewall spacer thereof. The integrated circuit field effect transistors are tested by performing SEM analysis on the integrated circuit substrate to detect the undesired conductive material on the sidewall spacer. The undesired conductive material is then etched from the sidewall spacer if the undesired material is detected by the SEM analysis.

    Abstract: An overlay measuring method includes irradiating an electron beam onto a sample, including a multi-layered structure of overlapped upper and lower patterns formed thereon, to obtain an actual image of the upper and lower patterns. A first image representing the upper pattern and a second image representing the lower pattern are obtained from the actual image. A reference position for the upper and lower patterns is determined from a design image of the upper and lower patterns. A position deviation of the upper pattern with respect to the reference position in the first image and a position deviation of the lower pattern with respect to the reference position in the second image are calculated to determine an overlay between the upper pattern and the lower pattern.
