    Abstract: A scanning electron microscope has an electron gun producing the electron beam, an objective lens for sharply focusing the beam onto the specimen, a tilting mechanism for tilting the specimen relative to the beam, and a power supply for applying the negative voltage to the specimen. This microscope further includes a cylindrical shield electrode mounted to surround the electron beam path between the objective lens and specimen. A front-end electrode is insulatively mounted to the front-end portion of the shield electrode that is on the specimen side. An electric potential substantially identical to the electric potential at the polepieces of the objective lens is applied to the shield electrode. An electric potential substantially identical to the potential at the specimen is applied to the front-end electrode.

    Abstract: The invention relates to a particle beam apparatus, in which very low target energies of the particles focused on the object can be set, with good imaging conditions. For this purpose, the beam guiding tube (5), from the anode (4) to behind the objective (6, 7) is at a high potential, which insures that the particles within the beam guiding tube have a high kinetic energy which is independent of the target energy. A braking electrode (9) arranged after the beam guiding tube, together with the object holder (10) and the object arranged thereon, is at a specimen potential UP which deviates from the ground potential and which has the same sign as the cathode potential UK. The specimen potential UP acts as the decelerating potential, by means of which the particles are braked to energies which can be below the energy value determined by the cathode potential UK. Thus even at the lowest target energies the object does not need to be brought to a high, high-voltage potential, so that object damage and high voltage flashovers are excluded. At the same time, the kinetic energy of the electrons within the beam guiding tube is largely independent of the target energy, so that the imaging relationships within the beam guiding tube are largely independent of the target energy.

    Abstract: A scanning microscope is provided for producing a scan image at high spatial resolution and in a low acceleration voltage area. An acceleration tube is located in an electron beam path of an objective lens for applying a post-acceleration voltage of the primary electron beam. The application of an overlapping voltage onto a sample allows a retarding electric field against the primary electron beam to be formed between the acceleration tube and the sample. The secondary electrons generated from the sample and the secondary signals such as reflected electrons are extracted into the acceleration tube through the effect of an electric field (retarding electric field) immediately before the sample. The signals are detected by secondary signal detectors located upwardly than the acceleration tube.
