Title: Electrostatic deflector for charged beams
Inventor: SHIOKAWA YOSHIRO
IPC: H01J37/147
Filed: 1986-11-27
Abstract: PURPOSE:To prevent effects of disturbance noises and to obtain high precision by composing electrode holders of a material whose volume resistivity is within a specific range. CONSTITUTION:Electrode holders 1 are composed of silicon carbide or the like whose volume resistivity is within the range of 10<2>OMEGAcm to 10<18>OMEGAcm. Though this composition allows the grounding resistance of deflecting electrodes 2 to be small in the order of 10<6>OMEGA, currents flowing in the electrodes 2 from a controlling source are almost no burden. Effects of disturbance noises by way of lead wires 5 decrease due to this small grounding resistance of the electrodes 2, and besides potential fluctuation caused by charged beams 3's scattering on the surfaces of the holders 1 is reduced so that high precision can be obtained.
