摘要： When forming a magnified image of a mask pattern on an object with a plurality of projection optical systems, projected images of the projection optical systems are formed to be accurately continuous to enable satisfactory pattern transfer. A first projection optical system directs light beam from point a on a mask to point A on a plate and forms a magnified image of the mask on the plate. A second projection optical system directs light beam from point b on the mask to point on the plate and forms a magnified image of the mask on the plate. A first line segment linking point A and point a′, which orthogonally projects point a on the plate, and a second line segment linking point B and point b′, which orthogonally projects point b on the plate PT, overlap each other as viewed in a non-scanning direction.

摘要： An apparatus for measuring dimensions of a micropattern has a photoelectric sensor for scanning an enlarged image of a pattern and detects the positions of the leading and trailing edges by use of a predetermined slice level from a photoelectric signal which is derived by this sensor, thereby detecting the interval between those edges. The slice level is corrected in accordance with the interval between the edges to be measured. An amount of correction is stored as a predetermined table. A determination is made by an interval discriminating section to see if the correction needs to be performed or not.

摘要： An exposure method includes first through third steps. In the first step, respective first and second illumination regions of a mask having a predetermined pattern are illuminated with an illumination light having a predetermined wavelength. In the second step, an image of the mask is formed, respectively, in first and second exposure regions (formed on a substrate) based on the illumination that passes through the first and second illumination regions. The first and second exposure regions each have a substantially polygonal shape defined by two parallel sides and two sides other than the two parallel sides. In the third step, the first and second exposure regions and the substrate are moved relatively in a first direction such that the first and second exposure regions are formed in different positions in a second direction which crosses the first direction.
