    摘要: An exposure method forms a plurality of patterns on a substrate, which is set on a stage of an exposure apparatus, through at least one mask. The method equalizes first positional linear error components of a pattern to be formed by the mask on a first coordinate system defined on the substrate to second positional linear error components of the pattern on a second coordinate system on which the stage is moved, by correcting coordinates for moving the stage on the second coordinate system. The method is capable of aligning the boundaries of patterns with each other on the substrate, to leave only positional linear error components on the patterns. These positional linear error components are removable to leave minimum random residual errors on the patterns, and therefore, the patterns on the substrate are precisely at specified positions.

    摘要: In one embodiment, a flare correction method is disclosed. The method can acquire a flare point spread function. The method can calculate a pattern density distribution in a first region of the mask, the distance from the pattern being equal to or shorter than a predetermined value in the first region. The method can calculate pattern coverage in a second region of the mask, the distance from the pattern being longer than the predetermined value. The method can calculate a first flare distribution with respect to the pattern by performing convolution integration between the flare point spread function corresponding to the first region and the pattern density distribution. The method can calculate a flare value corresponding to the second region by multiplying a value of integral of the flare point spread function corresponding to the second region by the pattern coverage. The method can calculate a second flare distribution by adding the flare value to the first flare distribution. In addition, the method can correct the pattern based on the second flare distribution.

    摘要: A main pattern region is projected to a substrate to be exposed while a defective portion including a defect generated in the main pattern region of an original mask is masked. Thereafter, a spare pattern corresponding to the defective portion is further projected on the substrate. In this manner, it is possible to prevent the defect of the main pattern region of the original mask from being transferred to the substrate. The pattern accuracy of the repair portion is the same as that of the exposed portion from the original mask. Therefore, the repair can be made with a high accuracy. Furthermore, it is possible to repair the defect produced at a pattern edge portion with a high accuracy without limitations given by a conventional repair technique.
