IPC: G03F1/84
Filed: 1994-02-22
Abstract: PURPOSE:To inspect a mask pattern positively with high accuracy by starting the pattern inspection based on the information of movement of an objective lens moving toward the center of the pattern. CONSTITUTION:Two patterns are selected arbitrarily from a plurality of patterns formed on a water 15 and then objective lenses 16a, 17a are aligned with the alignment marks of the patterns. Subsequently, the lenses 16a, 17a are shifted relatively to an inspection stage 14 up to the central parts of the patterns where the influence of aberration is suppressed. At that time, information (X, Y) relating to the shifting amount of the lenses 16a, 17a is stored. Upon finishing the positional correction, the lenses 16a, 17a are shifted relatively to the stage 14 according to the stored information and reset to the original position before the inspection is started. A die-to-die comparison system is employed for the inspection.
