Abstract: PURPOSE: To form an image of a pattern drawn on a mask (reticle) faithfully on a photosensitive substrate. CONSTITUTION: By a distance sensor 16, the distance from a pattern surface of a reticle R held on a reticle stage 14 (distance from a sensor surface) is detected in the longitudinal direction of the sensor, and a calculation part 20, on the basis of the distance at each measured point of the distance sensor, finds an equation or deflection curve of the reticle R with approximating to regression curve of secondary or fourth degree, and on the basis of this, deformation amount caused in the pattern on the reticule R is calculated.
