摘要： A matching degree computing apparatus is provided for comparing an input image and an object template image and computing a matching degree between an input image and an object template image based on the compared result. The computing apparatus includes a transforming unit for transforming the input image so as to be matched to the template object region and a computing unit for computing a matching degree between the transformed input image and the template image. The transforming unit provides a shaping unit for shaping a non-background region to the form of the template object region in the object corresponding region of the input image and a processing unit for arranging the non-background region contacting with the template object corresponding region so that the non-background region has no substantial impact on the matching degree in the object non-corresponding region of the input image.

摘要： When the lengths of FEM wafers are automatically measured, not only the sizes of targets, the lengths of which are to be measured, are often varied from those in registration, but also the patterns of the targets are often deformed. Therefore, it is difficult to automatically determine whether the length measurement is possible or not. Therefore, the following are executed with a semiconductor inspection system: (1) a process of identifying the position of the contour line of an inspected image using a distance image calculated from a reference image, (2) a process of calculating a defect size image based on the position of the contour line with respect to the identified distance image, and detecting a defect candidate from the defect size image, and (3-1) a process of, upon detection of the defect candidate, calculating the size of the detected defect candidate, or (3-2) a process of detecting a portion different between the first and second contour lines as the defect candidate.

摘要： According to the pattern search method of the present invention, detection of a detection image region relative to an observation image is performed by a pattern matching. An image whose size is substantially the same as that of the observation image is used as the detection image region. The detection image region is relatively displaced with reference to the observation image, thereby detecting a degree of similarity for a common region which is common to both of the region and the image. Displacement range of the detection image region is set in advance. If area of the common region is larger than a predetermined value, calculating the degree of similarity will be performed.
