Abstract
PURPOSE:To reduce contamination by illuminating an ion beam guided into a device main body to a sample through a conducting tube fixed at the constant potential. CONSTITUTION:A conducting tube 7 made of stainless steel, nonmagnetic material such as ceramic material with good conductivity, magnetic material such as permalloy, or a combination of the nonmagnetic material and the magnetic material and fixed at the ground potential in the frame of an electron beam illuminating device main body is provided, and an ion beam is illuminated to a sample 6 through this conducting tube 7. The conducting tube 7 shields the ion beam from the electric field or the magnetic field or both of them in the frame, the mutual interference between the electron beam and the ion beam can be decreased, thus the focusing property of the ion beam is rarely reduced, and the ion beam with high energy density can be illuminated to the sample. Contamination can be thereby reduced.
