    Abstract: Computer-implemented methods for detecting defects in reticle design data are provided. One method includes generating a first simulated image illustrating how the reticle design data will be printed on a reticle using a reticle manufacturing process. The method also includes generating second simulated images using the first simulated image. The second simulated images illustrate how the reticle will be printed on a wafer at different values of one or more parameters of a wafer printing process. The method further includes detecting defects in the reticle design data using the second simulated images. Another method includes the generating steps described above in addition to determining a rate of change in a characteristic of the second simulated images as a function of the different values. This method also includes detecting defects in the reticle design data based on the rate of change.

    Abstract: 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).

    Abstract: The pattern defect inspection apparatus is operable to detect defects by comparing a detection image, which is obtained through scanning by an image sensor those patterns that have the identical shape and are continuously disposed on the object under tested at equal intervals in row and column directions, with a reference image obtained by scanning neighboring identical shape patterns in the row and column directions. This apparatus has a unit for generating an average reference image by statistical computation processing from the images of identical shape patterns lying next to the detection image including at least eight nearest chips on the up-and-down and right-and-left sides and at diagonal positions with the detection image being intermediately situated. The apparatus also includes a unit that detects a defect by comparing the detection image to the average reference image thus generated.

    Abstract: A design for inspecting specimens, such as photomasks, for unwanted particles and features such as pattern defects is provided. The system provides no central obscuration, an external pupil for aperturing and Fourier filtering, and relatively relaxed manufacturing tolerances, and is suited for both broad-band bright-field and laser dark field imaging and inspection at wavelengths below 365 nm. In many instances, the lenses used may be fashioned or fabricated using a single material. Multiple embodiments of the objective lensing arrangement are disclosed, all including at least one small fold mirror and a Mangin mirror. The system is implemented off axis such that the returning second image is displaced laterally from the first image so that the lateral separation permits optical receipt and manipulation of each image separately. The objective designs presented have the optical axis of the Mangin mirror image relay at ninety degrees to the optical axis defined by the focusing lenses, or an in-line or straight objective having one ninety degree bend of light rays.
