Patent JP-H03183145-A (JP)
Title: Electron beam apparatus
Inventor: ITO AKIO
IPC: H01J37/28
Filed: 1989-12-12
Abstract: PURPOSE:To eliminate an influence caused by a low-frequency noise, to reduce a measuring error and to shorten a measuring time by finding a difference between the following: a signal component which has passed a high-pass filter out of pulsed secondary electronic signals; and a signal component which has sampled-and-held an output signal of the high-pass filter. CONSTITUTION:An EB pulse-generation control signal is input, as a strobe signal, to a sample-and-hold circuit 22 form a control circuit 11; an input secondary electronic signal whose noise has been eliminated by using a high-pass filter 21 is held at the timing of the strobe signal, i.e., at the timing to generate an EB pulse; a voltage is held for a definite time. Since a differential amplification output of a smaple-and-hold signal and a high-pass filter output signal always uses a level at the rise time of a pulse signal as a reference, a pulse height coincides with a peak value of a pulse. When an output signal of a differential amplifier 23 is sampled at the timing at which the secondary electronic signal becomes maximum and is A-D-converted, an influence by a low-frequency noise is eliminated and a measuring error can be reduced.
