    摘要: An image correction device for use in pattern inspection apparatus is disclosed. This device includes a pattern extraction unit for extracting a pattern, as a cut-and-paste pattern, from a pattern existence region of an inspection reference pattern image and a pattern image of a workpiece being tested. The device also includes a pattern pasting unit for pasting the cut-and-paste pattern in blank regions of the reference and under-test pattern images to thereby create a pasted reference pattern image and a pasted test pattern image. The device further includes an equation generator for generating by linear predictive modeling a set of simultaneous equations relative to the pasted reference and test pattern images, a parameter generator for solving these equations to obtain a model parameter(s), and a unit for creating a corrected pattern image by the linear predictive modeling using the model parameter(s).

    摘要: An image correction device for use in a pattern inspection apparatus is disclosed, which has automatic adaptability to variations in density of a pattern image of a workpiece being tested. The device is operable to identify a two-dimensional (2D) linear predictive model parameters from the pattern image of interest and determine the value of a total sum of these identified parameters. This value is then used to switch between a corrected pattern image due to the 2D linear prediction modeling and a corrected image that is interpolated by bicubic interpolation techniques. A pattern inspection method using the image correction technique is also disclosed.

    摘要: An image correction method employable in a pattern inspection method for emitting light falling onto a workpiece with a pattern formed thereon and for inspecting a pattern image resulting from the pickup of an optical image of the workpiece by comparing it to a corresponding fiducial pattern image is disclosed. The method includes the step of generating a system of equations describing therein an input/output relation using a 2D linear prediction model(s) with respect to the pattern image being tested and the fiducial pattern image. Then, estimate the equation system by least-squares methods to thereby obtain a parameter of the equation system. Next obtain a centroid of the parameter. Then perform interpolation using the value of the centroid, thereby to generate a corrected image. A pattern defect inspection method using the image correction method is also disclosed.
