摘要:
Observation using an FIB image is enabled without causing any damage to a designated region. To this end, an ion beam scanning-prohibited region is set in a sample by using an image acquired by a charged particle beam other than an ion beam, or an image prepared as external data as a peripheral image including the designated region of a sample. Thereafter, the image used to set the ion beam scanning-prohibited region is exactly superimposed on an FIB image acquired for regions except the ion beam scanning-prohibited region, thereby forming an image including the ion beam scanning-prohibited region on which ion beam scanning has not been performed.

摘要:
A hole in a sample from which a sample piece has been extracted with a focused ion beam is filled at high speed using ion beam gas assisted deposition. A method of filling the hole by using the ion beam includes a step of irradiating the hole formed in a face of the sample with the ion beam to thereby form an ion beam gas-assisted deposition layer in the hole. The ion beam gas-assisted deposition layer is formed in the hole while controlling the area to which the ion beam is irradiated so as to cause the ion beam to fall on a part of a side wall of the hole and to not fall on another part of the side wall in an area scanned with the ion beam. The filled hole may then be covered with a protective film.

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.
摘要:
Disconnection defects, short-circuit defects and the like in wiring patters 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).

Provided is a technique to perform FIB milling, in spite of its sample dependency, effectively into a desired shape without influences of individual differences among operators. A charged particle beam device includes an ion beam optical system device configured to irradiate a sample with an ion beam generated at an ion source; a controller thereof; an element detector configured to detect elements constituting the sample; a controller thereof; and a central processor configured to automatically set conditions for the sample based on the element specified by the element detector.
摘要:
Provided are a device and method capable of machining a machining target such as a sample, a probe, or a sample table without requiring a high degree of device operation skill. First, a shape generation process of determining a shape of a machining target on the basis of an ion beam scanning signal and an absorption current of the machining target is performed. Next, a machining pattern positioning process of positioning a machining pattern over an image of the machining target is performed. Further, an ion beam stopping process of stopping ion beam irradiation is performed from a result of comparison between the image of the machining target and the machining pattern while the machining target is machined through the ion beam irradiation.
