The e-beam inspection tool may comprise s high voltage plate, such as a stationary high voltage plate connected to the vacuum chamber such as the plates 650 in FIG. 6, or a high voltage plate provided in the positioning device 610. In order to reduce an additional volume that would be required for the magnetic shield, the magnetic shield may be combined with the high voltage plate of the e-beam inspection tool. The high voltage plate and the magnetic shield may form separate layers connected to each other, whereby each layer provides its intended function. Alternatively, the high voltage plate and the magnetic shielding may be integrated, for example by providing high voltage plate using a mu-metal or similar type of material.
