ABSTRACT:
A method of imaging a fine pattern having a group of lines extending along orthogonal first and second directions and a group of lines extending along a third direction different from the first and second directions includes illuminating the pattern obliquely, to form an image of the line pattern. Illumination beams along the first, second and third directions, respectively, each has an intensity sufficiently lowered as compared with that of a particular illumination beam along a particular direction different from the first, second and third directions.
