    Abstract: The illuminating beam 4 emitted from the cathode 1 is incident on a deflector 3. In a state in which a voltage is applied to the deflector 3, the optical path of the illuminating beam 4 is altered by the deflector 3; the illuminating beam 4 then passes through a common electron optical system 7, and illuminates the surface of the sample 6. In cases where no voltage is applied to the deflector 3, the illuminating beam 4 passes directly through the deflector 3, and is absorbed by an electron absorbing plate 17. The illuminating beam 4 is attenuated when it passes through the common electron optical system 7, so that the energy of this beam 4 is close to 0 [eV] at the point in time at which the beam 4 reaches the surface of the sample 6. When the illuminating beam 4 is incident on the sample 6, reflected electrons 8 are generated from the sample 6. These reflected electrons 8 pass through the common electron optical system 7, and in a case where no voltage is applied to the deflector 3, these reflected electrons 8 pass through the image focusing electron optical system 9, so that the electrons are projected onto an MCP detector 10.

    Abstract: A method for reducing particles during ion implantation is provided. The method involves the use of an improved Faraday flag including a beam plate having thereon a beam striking zone comprising a recessed trench pattern on which the ion beam scans to and fro. An ion beam selected from the mass analyzer is blocked by the Faraday flag in a closed position between the mass analyzer and the semiconductor wafer. A beam current of the ion beam impinging on the beam striking zone of the beam plate is measured. After the beam current measurement, the Faraday flag is removed such that the ion beam impinges on the semiconductor wafer.

    Abstract: An electron beam apparatus prevents a rapid increase of dosage caused by stoppage or deceleration of movement and protects the specimen when the specimen is irradiated with the electron beam while the specimen and the electron beam are being relatively moved. An electron beam source outputs the electron beam. The dosage of electron beam irradiated per unit area of the specimen is measured. A storage section stores a predetermined dosage per unit area in memory for the specimen. A detector detects over exposure of the electron beam when the measured dosage per unit area is greater than the dosage per unit area stored in the storage section. A controller controls the electron beam source to reduce the dosage per unit area of the electron beam lower than the dosage per unit area stored in the storage section.

    Abstract: The present invention relates to an exposure method of a multi-beam type in which a stage mounting a sample to be exposed is continuously moved in a first direction, and charged-particle beams are controlled so as to form a desired beam shape as a whole, and in which a pattern is formed on the sample by deflecting the charged-particle beams by a main deflector and a sub deflector. Patterns to be drawn are divided into pattern data on a cell stripe basis which corresponds to an area which can be exposed when the sub deflector scans the charged-particle beams one time. The pattern data on the cell stripe basis is stored into a memory. Then, position data indicative of cell stripes is stored, in an exposure sequence, together with address information concerning the memory in which the pattern data is stored. The deflection amount data relating to the main deflector and the sub deflector is calculated from the position data. Patterns are drawn on the wafer by using the pattern data and the deflection amount data.
