  • 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: 8189040
    Abstract: There is provided a recipe generation apparatus and method for reducing the time required to reflect an optimal value and changed value in an input file by automatically reflecting a value obtained by optimizing an input file for recipe generation in the input file for recipe generation. This invention eliminates the inconvenience of manually reflecting changes in an input file for recipe generation by automatically reflecting changed values in the input file for recipe generation after editing a provisionally generated off-line recipe and achieves a reduction in processing time. This invention also provides a method for automatically generating an off-line recipe and a file for recipe generation from a recipe of a scanning electron microscope (see FIG. 3).

  • Patent number: 8019161
    Abstract: A workpiece size measurement method suitable for length measurement of multilayered circuit elements with increased complexities is disclosed. This method employs a technique for changing measurement conditions in a way pursuant to either an image of workpiece or the situation of a target semiconductor circuit element to be measured when measuring pattern sizes on the workpiece image using design data of the semiconductor circuit element. With such an arrangement, adequate measurement conditions are selectable in accordance with the state of workpiece image and/or the state of a circuit element formed on the workpiece, thereby making it possible to improve the measurement efficiency. A workpiece size measurement apparatus using the technique is also disclosed.
