  • Patent number: 7593596
    Abstract: A candidate pixel generating unit searches a path-undetermined adjacent pixel j which is adjacent around a parent pixel i, and, with respect to the searched adjacent pixel j, generates a candidate pixel having data {j(i,|Wij|)} in which the parent pixel i and magnitude |Wij| of a phase difference Wij in which phase skip between the pixels is corrected are combined. The registration control unit registers the pixel to a heap having a function of ordering the registration order, and order the pixel, if the weight |Wij| is equal to or more than a predetermined threshold value TH; and registers the pixel to a queue not having the function of ordering the registration order if it is less than the threshold value TH. A path determination unit prioritizes the queue to retrieve and eliminate one candidate pixel, and determines a path between the eliminated candidate pixel and the parent pixel.

  • Patent number: 7443516
    Abstract: A reference-height calculating unit calculates an original height of a distortion detecting mirror when a distortion detecting mirror and a reference mirror are set in parallel to each other. A height measuring unit measures mirror heights when the distortion detecting mirror is tilted in directions of an X axis and a Y axis. A contour-line calculating unit calculates a pair of contour lines based on the mirror heights. An intersection calculating unit calculates an intersection of the contour lines. A storing unit stores coordinates to which height of predetermined coordinates are moved by distortion in a correction table. A distortion correcting unit corrects the distortion based on the correction table.

  • Patent number: 6104493
    Abstract: The bump height is measure din a sample area on a wafer, the bump height distribution on the wafer is estimated on the bases of the measured value, the portion where the estimated height distribution is out of a predetermined range is determined as an inspection area, and the bump height is measured in the inspection area, and a chip area having a bump height out of a predetermined range is judged to be defective. Data of the inspection areas and inspection results are accumulated, and the inspection density is renewed on the basis of the accumulated data. In another method, the inspection area is divided into rectangular blocks so that each block has a width of approximately equal to a light beam scanning length and a distance between any adjacent bumps in the feeding direction is less than a predetermined value, feeding path being perpendicular to the scanning direction.

  • Patent number: 4805224
    Abstract: Disclosed is a pattern matching method and apparatus, in which an object pattern is collated with a master pattern using pattern matching. As a first step, an area corresponding to a master pattern size is sequentially extracted from a master sample image for forming the master pattern, each extracted pattern is collated and the other patterns in the master sample image. An extracted pattern which has a minimum similarity to all the other patterns, and, as a result, shows the most distinctive pattern, is used for the master pattern. Using the present method and apparatus, pattern matching having a higher recognition rate can be performed. Further, using the present pattern matching method, an apparatus can be obtained for positioning the object to be recognized with a highest positioning accuracy.
