  • Patent number: 8788981
    Abstract: In a method and apparatus for quantitatively evaluating two-dimensional patterns, a reference coordinate system is set in order to convert pattern edge information (one-dimensional data) acquired by measurement using an existing critical dimension machine into coordinate data. Thus, a pattern is converted into coordinate information. Next, a function formula is determined from this coordinate information by approximate calculation and a pattern is represented by the mathematical expression y=f(x). Integrating y=f(x) in the reference coordinate used when calculating the coordinate data gives the area of the pattern, whereby it is possible to convert the coordinate data to two-dimensional data.

  • 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.

  • Publication number: 20080250380
    Abstract: A method capable of quantitatively evaluating two-dimensional patterns and a system to which the method is applied are provided. In the present invention, a reference coordinate system is set in order to convert pattern edge information (one-dimensional data) acquired by measurement using an existing critical dimension machine into coordinate data. Thus, a pattern is converted into coordinate information. Next, a function formula is determined from this coordinate information by approximate calculation and a pattern is represented by the mathematical expression y=f(x). Integrating y=f(x) in the reference coordinate used when calculating the coordinate data gives the area of the pattern, whereby it is possible to convert the coordinate data to two-dimensional data.
