Abstract: This cross-section observation device bombards an object with a charged particle beam to repeatedly expose cross-sections of the object, bombards at least some of the cross-sections from among the plurality of the exposed cross-sections with a charged particle beam to acquire cross-sectional image information describing each of the at least some of the cross-sections, generates for each of these cross-sections a cross-sectional image described by the cross-sectional image information acquired, and generates a three-dimensional image in which the generated cross-sectional images are stacked together.

Abstract: A sample holder HL capable of efficiently applying a pressure to an observation surface of a sample SAM is provided. The sample holder HL includes a fixed electrode 4b, a movable electrode 5, and a pressure applying member 6 attached to the movable electrode 5 and having a function to move the movable electrode 5 in a horizontal direction. When the sample SAM is held between a side surface of the fixed electrode 4b and a side surface of the movable electrode 5, an upper surface of the sample SAM is located within a range of a width of the pressure applying member 6 at a position where the pressure applying member 6 is in contact with the movable electrode 5 in the Z direction.

Abstract: Disclosed is a charged particle radiation apparatus capable of capturing a change in a sample due to gaseous atmosphere, light irradiation, heating or the like without exposing the sample to atmosphere. The present invention relates to a sample holder provided with a sample stage that is rotatable around a rotation axis perpendicular to an electron beam irradiation direction, the sample holder being capable of forming an airtight chamber around the sample stage. A sample is allowed to chemically react in any atmosphere, and three-dimensional analysis on the reaction is enabled. A sample liable to change in atmosphere can be three-dimensionally analyzed without exposing the sample to the atmosphere.

Abstract: A specified position in an array structure in which a reference pattern is displayed repetitively through reference pattern counting is identified. In an array structure image, the pattern detection estimating area generated from a starting point, the address of the starting point, and a unit vector are compared with a pattern detected position found in pattern matching with the reference pattern image, to execute pattern counting while determining correct detection, oversights, wrong detection, etc. Array structure images are photographed sequentially while moving the visual field with the use of an image shifting deflector to continue the pattern counting started at the starting point to identify the ending point specified with an address. If the ending point is not reached only with use of the image shifting deflector, the visual field moving range of the image shifting deflector is moved with use of a specimen stage.

Abstract: A probe driving method and a probe apparatus for bringing a probe into contact with the surface of a sample in a safe and efficient manner by monitoring the probe height. Information about the height of the probe from the sample surface is obtained by detecting a probe shadow (54) appearing immediately before the probe contacts the sample, or based on a change in relative positions of a probe image and a sample image that are formed as an ion beam is irradiated diagonally.

Abstract: Disconnection defects, short-circuit defects and the like in wiring patterns of submicron sizes within TEGs (a square of 1 to 2.5 mm for each) numerously arranged in a large chip (a square of 20 to 25 mm) can be inspected with respect to all the TEGs, with good operability, high reliability and high efficiency. A conductor probe for applying voltage to the wiring patterns by mechanical contact is composed of synchronous type conductor probe that synchronizes with movement of a sample stage (16), and fixed type conductor probe means (21) that is relatively fixed to an FIB generator (10). Positions of probe tips are superimposed to an SIM image and displayed on a display unit (19).
