Title: Electric charge neutralization method and device for ion beam and drive processor and surface measuring device
Inventor: HIRAOKA SUSUMU
IPC: H05H3/02
Filed: 1991-11-05
Abstract: PURPOSE:To prevent any increase in the size of a device by increasing the neutralization rate of electric charge of ion beams and avoiding gas diffusion towards the outside of the electric charge neutralized area. CONSTITUTION:Ion beams generated from an ion source 5 and molecular beams emitted from a molecular beam nozzle 7 are intersected to each other thereby neutralizing the electric charge of the ion beams. Not-neutralized ions are deflected by a deflection plate 8 so as not to be incident on a sample 4. Thereby, the pressure within the molecular beams may be kept to be high and the neutralization possibility of electric charge of the ion beams may be maintained high and at the same time the gas diffusion into the ion beam source may be prevented. Accordingly, the gas diffusion towards the outside of the electric charge neutralizing area may be avoided and also the electric charge neutralization within an extremely narrow area may be performed thereby permitting the miniaturization of the device.
