Abstract

PURPOSE:To shorten both the decision time and the exposure time by deciding the cross-sectional area of the beam or the length of the short side through the electric circuit and also varying the beam irradiation quantity. CONSTITUTION:Deflecting signals X1 and Y1 to decide the beam cross-sectional area are multiplied 22 and amplified 21 by electric computer 16 and via D/A conversion 20. The irradiation time is decided 18 by the multiplication signal, and the signal of irradiation optimum to the area is transmitted to data circuit 17 via A/D converter 19. Circuit 17 supplies the information of the pulse duration and interval based on the irradiation cut-off time signal given from the electric computer and then generates 17a the pulse to supply it to blanking electrode 15. Electrode 15 gives the ON/OFF control to the beam. Then the cross-sectional area of the electron beam is formed into a size equivalent to the product of deflecting signals X1 and Y1, securing irradiation onto test sample 6 with the optimum time. With this method, the pattern data quantity can be reduced greatly, and both the decision time and the exposure time can be shortened.
