Abstract
PURPOSE:To improve picture-drawing accuracy as well as throughput by additionally connecting a new calculator and a D-A converter including a reversible counter and an amplifier to a summation amplifier which controls a deflection means of an exposure device for providing a rapid positional correction to a sample stand. CONSTITUTION:Electron beams from an electron gun 11 are deflected by means of a deflection means 10 and applied onto a material 12 to be exposed, which is mounted on a movable sample stand 13. Connected to the deflection means 10 is a summation amplifier 9 which receives a deflection signal from a picture-drawing signal generating integrator 1 through a level adjusting amplifier 2. A presettable reversible counter 6 is also connected to the summation amplifier 9 through a D-A converter 4 and an amplifier 5 to correct the positon of the sample stand 13. There are also provided a length measuring unit 14 and a computor and the outputs of them are applied to the amplifier 9 through the reversible counter 6, D-A converter 7 and amplifier 8 to compersate for the change of the sample stand 13 by use of the positional information read off at the unit 14.
