Abstract: A specimen machining device includes an ion source which irradiates a specimen with an ion beam, a first rotating body (specimen holder) that holds the specimen and is rotatable about a first axis serving as a rotation axis, and a second rotating body on which the first rotating body is disposed and which is rotatable about a second axis serving as a rotation axis different from the first axis. The specimen machining device irradiates the specimen with the ion beam while moving the specimen by the rotation of the first rotating body and the rotation of the second rotating body.

Abstract: An ion milling apparatus includes a pair of shielding members sandwiching a sample, and an ion source configured to irradiate the sample with an ion beam. The ion milling apparatus is configured to be capable of irradiating the sample with the ion beam in a first mode of irradiating the sample with the ion beam via one shielding member and in a second mode of irradiating the sample with the ion beam via the other shielding member.

Abstract: An ion milling apparatus has: a sample holder including a shield member for shielding the sample except for a portion to be milled; and a sample locking member cooperating with the shield member such that the sample is sandwiched and held therebetween. The shield member has an edge portion that determines a milling position on or in the sample. The sample locking member is disposed downstream of the edge portion in the direction of irradiation by the ion beam and has a support portion cooperating with the edge portion to support the milled portion therebetween. The support portion has a first surface making contact with the sample and a second surface making a given angle to the first surface. The given angle is equal to or less than 90°.
