摘要： While an image obtained by a general electron microscope is affected by the shape and material of an object specimen, an image obtained from mirror electrons is affected by the shape of an equipotential surface on which the mirror electrons are reflected, thereby the image interpretation is complicated. A mirror electron microscope of the present invention is provided with the following means for controlling a reflecting plane of the mirror electrons according to the structure of an object pattern to be measured or a concerned defect.1) Means for controlling a potential difference between a specimen and an electron source equivalent to a height of a reflecting plane of a mirror electron beam according to a type, an operation condition of an electron source, and a type of a pattern on a specimen. 2) Means for controlling an energy distribution of an illuminating beam with an energy filter 9 disposed in an illuminating system. It is thus possible to inspect a specimen according to a size and a potential of a pattern, which are distinguished from others.

摘要： There is a need for inspecting a heightwise variation in a sample. A holder holds a sample. A charge control unit charges the sample held by the holder. A retarding power supply applies a voltage to the sample held by the holder. An electro-optic system radiates an electron beam to the sample applied with a voltage by the retarding power supply and images a mirror electron returning near the surface of the sample. An image processing unit processes a mirror image resulting from imaging the mirror electron. The image processing unit outputs information corresponding to a difference between mirror images, i.e., a mirror image acquired by imaging the mirror electron and a mirror image for a prepared standard preparation, as a heightwise variation in a sample.

摘要： In a multi-charged-particle-beam apparatus, when an electric field and voltage on a surface of a specimen are varied according to characteristics of the specimen, a layout of plural primary beams on the surface of the specimen and a layout of plural secondary beams on each detector vary. Then, calibration is executed to adjust the primary beams on the surface of the specimen to an ideal layout corresponding to the variation of operating conditions including inspecting conditions such as an electric field on the surface and voltage applied to the specimen. The layout of the primary beams on the surface of the specimen is acquired as images displayed on a display of reference marks on the stage. Variance with an ideal state of the reference marks is measured based upon these images and is corrected by the adjustment of a primary electron optics system and others.

摘要： With a multi-beam type charged particle beam apparatus, and a projection charged particle beam apparatus, in the case of off-axial aberration corrector, there is the need for preparing a multitude of multipoles, and power supply sources in numbers corresponding to the number of the multipoles need be prepared. In order to solve this problem as described, a charged particle beam apparatus is provided with at least one aberration corrector wherein the number of the multipoles required in the past is decreased by about a half by disposing an electrostatic mirror in an electron optical system.
