Abstract: An information processing device processes target information described using identifiers formed from a symbol, a product operator that joins together factors containing one or more of the identifiers and thereby forms a string of ordered factors, and a sum operator that joins together terms containing one or more of the factors and thereby forms an expression that is a combination of the terms. Also, information processing device includes a dividing unit that divides the target information into a plurality of terms at a predetermined position; and a transmission unit that associates positional information with at least any of the factors contained in the terms resulting from the division and causes each of the terms resulting from the division to be held in any of a plurality of server devices, where the positional information contains an occurrence sequence of the terms in the target information and an occurrence sequence of the factors in the terms.

Abstract: An apparatus has a holder member (21) which holds a sample (3), and a removing beam source (13) which irradiates an inert ion beam onto a cross section (4) of the sample (3) held by a holder member (21) and removes a fracture layer on the cross section (4). Then, the removing beam source (13) is disposed on the holding end side of the sample (3) with respect to the normal L of the cross section (4) so that the irradiating direction of the inert ion beam is tilted at the tilt angle ? to the normal L with respect to the cross section (4).

Abstract: There is provided a liquid metal ion beam irradiation device for irradiating a specific portion of a sample 6 with a prescribed liquid metal ion beam so as to form a cross section, and a gaseous ion beam irradiation device 7 for scanning a prescribed region (observation region) of the cross section using a gaseous ion beam focused to a prescribed diameter and removing a damaged layer on the prescribed region.

Abstract: An ion beam processing device has a sample holder for fixing a sample on which a section has been formed by irradiation of a specified focused ion beam from a surface side, and gas ion beam irradiation device for irradiating a gas ion beam to a region of the sample fixing using the holder member that contains the section to remove a damage layer on the section. The gas ion beam from the gas ion beam irradiation device irradiates the section from a rear surface side of the sample at a specified incident angle.

Abstract: A thin film is etched by irradiating charged particles to a surface of the thin film. An etching time of the thin film is measured by observing a change in intensity of secondary charged particles emitted by etched portions of the thin film. A thickness of the thin film is calculated in accordance with the measured etching time.
