摘要： A fast atom beam source is capable of emitting a fast atom beam with low energy efficiently and is compact. A reaction gas mixed with a halogen or a halide is introduced into a fast atom beam source casing through a plate-shaped anode, and gas ions that are produced by a plasma discharge induced at a relatively low discharge voltage are converted into a fast atom beam, which is emitted from fast atom beam emitting holes provided in a plate-shaped cathode that is disposed opposite the anode.

摘要： An electro-optical inspection apparatus prevents adhesion of dust or particles to a sample surface, wherein a stage on which a sample is placed is disposed inside a vacuum chamber that can be evacuated, and a dust collecting electrode is disposed to surround a periphery of the sample. The dust collecting electrode is applied with a voltage having the same polarity as a voltage applied to the sample and an absolute value that is the same or larger than an absolute value of the voltage. Because dust or particles adhere to the dust collecting electrode, adhesion of the dust or particles to the sample surface can be reduced. Instead of using the dust collecting electrode, it is possible to form a recess on a wall of the vacuum chamber, or to dispose on the wall a metal plate having a mesh structure to which a predetermined voltage is applied.

摘要： A system for further enhancing speed, i.e. improving throughput in a SEM-type inspection apparatus is provided. An inspection apparatus for inspecting a surface of a substrate produces a crossover from electrons emitted from an electron beam source 25•1, then forms an image under a desired magnification in the direction of a sample W to produce a crossover. When the crossover is passed, electrons as noises are removed from the crossover with an aperture, an adjustment is made so that the crossover becomes a parallel electron beam to irradiate the substrate in a desired sectional form. The electron beam is produced such that the unevenness of illuminance is 10% or less. Electrons emitted from the sample W are detected by a detector 25•11.

摘要： An electron beam apparatus comprises a TDI sensor 64 and a feed-through device 50. The feed-through device has a socket contact 54 for interconnecting a pin 52 attached to a flanged 51 for separating different environments and the other pin 53 making a pair with the pin 52, in which the pin 52, the other pin 53 and the socket contact 54 together construct a connecting block, and the socket contact 54 has an elastic member 61. Accordingly, even if a large number of connecting blocks are provided, the connecting force may be kept to such a low level as to prevent the breakage in the sensor. The pin 53 is connected with the TDI sensor 64, in which a pixel array has been adaptively configured based on the optical characteristic of an image projecting optical system. That sensor has a number of integration stages that can reduce the field of view of the image projecting optical system to as small as possible so that a maximal acceptable distortion within the field of view may be set larger. Further, the number of integration stage may be determined such that the data rate of the TDI sensor would not be reduced but the number of pins would not be increased as much as possible. Preferably, the number of line count may be almost equal to the number of integration stages.
