  • Patent number: 8581187
    Abstract: An amount of displacement and an overlapping area between first and second patterns formed through a double patterning lithography process can be determined. The first pattern is formed by a first exposure while the second pattern is formed by a later second exposure. A first image of the first pattern is formed prior to the formation of the second pattern. A second image of both patterns is formed after the formation of the second pattern. A two-step matching process between combined information and images of the first and second patterns is performed. The combined information includes information regarding the first pattern, as formed, combined with design information of the second pattern. Based on a moving amount of the design information of the second pattern, a displacement amount between the first and second patterns is determined.

  • Patent number: 8552371
    Abstract: There is provided a method for setting a suitable imaging magnification for each of a plurality of measurement places in a charged particle beam apparatus which images a semiconductor pattern. For a given measuring point coordinate, a line segment or a vertex representing a change in concavity and convexity near the measuring point coordinate is searched, and an imaging magnification is set so that coordinates on a sample corresponding to both ends which gives a length that serves as a reference falls in a field of view of the charged particle beam apparatus by letting a minimum distance be the reference, of distances between line segments representing a change in concavity and convexity from the measuring point coordinate or a distance between neighboring vertexes.

  • Patent number: 8180140
    Abstract: To create a template for use in image recognition based on design data, luminance information is set for each area in the template based on the information regarding the region defined by the template. The luminance information may be set based on material information, pattern size information of a pattern arranged in the region defined by the template, and layer information of the region defined by the template. Alternatively, luminance information may be set based on material information, setup conditions of the scanning electron microscope, and pattern outline information of a pattern arranged in the region defined by the template.

  • Publication number: 20110096309
    Abstract: A method and system for evaluating a lithographic pattern obtained using multiple-patterning lithographic processing are presented. In one aspect, the method includes aligning a target design with a lithographic pattern. The target design may comprise a first design and a second design. The method further comprises identifying in the lithographic pattern a stitching region based on a region of overlap between the first design and the second design. The method further comprises determining for the identified stitching region whether a predetermined criterion is fulfilled. In some embodiments, determining whether a predetermined criterion is fulfilled may comprise determining a line or trench minimum width. Alternately or additionally, determining whether a predetermined criterion is fulfilled may comprise determining a stitching metric for the identified stitching region, and evaluating whether or not the stitching metric fulfills the predetermined criterion.

  • Publication number: 20090304286
    Abstract: An object of the present invention is to maintain the ease with which a template is created based on design data without acquiring an actual image, which is achieved by providing the template with equivalent information contained by a template used for image recognition that involves same-type image comparison, and to improve image recognition performance by increasing the matching rate between a template and an actual image. To achieve the above object, the present invention provides a method, apparatus, and program for creating based on design data a template that is used for image recognition, wherein luminance information is set for each area in the template based on the material information of the region defined by the template.
