Abstract: PROBLEM TO BE SOLVED: To detect the change of the light path length reflected the variation of a projecting/exposing optical system by a method wherein a laser interferometer, having a light path, is provided between an original sheet and the material to be exposed, and the length of the light path between the original sheet, reflecting the optical variation in the projecting/exposing system, and the material to be exposed, is detected. SOLUTION: When a reticle 1 is successively exposed to a wafer 3, the length of light path from the reticle 1 to the wafer 3 is extended because the position of the is unchanged. At that time, the signal of a photoelectric detector 10 showing the wafer height is changed from the phase 0 which is measured by a send. ahead process because the light path length between the reticle 1 and the wafer 3 is already measured. A stage 14 is moved to the photoaxial direction of a projection lens by a control system 18 in such a manner that the above- mentioned change is cancelled. As a result, the change of light path length is corrected, and the height of the surface of the wafer 3 can be positioned and exposed at the best focus position at all times.
