Abstract

PURPOSE:To automatically eliminate errors peculiar to an optical system, by applying a signal detected by one of two optical apparatus in the same optical system to the other. CONSTITUTION:An electron-beam detecting apparatus 1 has an electron-beam emitter 3, an electron-beam regulator 5, an electron-beam scanner 6, a pattern memory 8 having materials different in secondary-electron emission efficiency from each other correspondingly to patterns to be lighographed, and a secondary-electron detector 10 for detecting the amount of secondary electrons reflected from the memory 8. An electron-beam lithography apparatus 2 has devices with the same structures as those in the apparatus 1, such as an electron-beam scanner 6', and an electron-beam modulator 12 whose beam intensity is controlled by the output signal of the detector 10 or the signal obtained by stepwise discriminating the output signal between two kinds of level on the basis of a predetermined value. A scanning signal generator 7 is used for the apparatus 1 and 2 in common.
