Patent ID: 8405053

Claim:
A focused ion beam apparatus, comprising: a sample stage which is movable in three-dimensional directions, and is for carrying a specimen; an ion beam irradiating optical system for irradiating a focused ion beam to the specimen; a gas nozzle for supplying a deposition gas; a holder clasp for mounting a sample holder to which a micro-specimen, extracted from the specimen by irradiating the focused ion beam, is fixed through a fixing deposition film, the holder clasp being mounted relative to the sample stage; a specimen transferring unit provided within a sample chamber and having a probe to which the micro-specimen can be joined through a joining deposition film, the specimen transferring unit transferring the micro-specimen which is extracted from the specimen to the sample holder; and the sample chamber in which the sample stage, the holder clasp and the probe are laid out, providing a state at a vacuum, wherein, the specimen transferring unit holds the probe which is configured to join through the joining deposition film to the micro-specimen extracted from the specimen, and the sample stage is configured to move where the sample holder mounted on the holder clasp is into an irradiated range of the focused ion beam, and the specimen transferring unit is configured to approach the probe to the sample holder in the sample chamber, and the gas nozzle is configured to supply the deposition gas for fixing the micro-specimen to the sample holder in the sample chamber through the fixing deposition film, and the ion beam irradiating optical system is configured to irradiate the focused ion beam to the micro-specimen fixed to the sample holder for fabricating the micro-specimen for observations using a transmission electron.
