Filed: 1985-03-12
Abstract: PURPOSE:To minimize voltage fluctuation caused when minute electric discharge occurs in electrostatic lenses by applying electric potentials to the electrostatic lenses directly from columns of an accelerating-voltage-producing circuit consisting of a Cockcroft-Walton circuit. CONSTITUTION:An ion beam from an ion source 2 is accelerated by an accelerator tube 5 and the accelerated ion beam is irradiated upon a sample 11 through a capacitor lens 7 and an objective 9. The power supply of the focused ion beam device of this invention consists of a Cockcroft-Walton circuit 20 consisting of diodes and capacitors connected in multiple stages.
