Abstract:
1. A specimen holder for a charged-particle beam apparatus for supporting specimens, being installed in the charged-particle beam apparatus obtaining information of plural specimens at a same time to observe the specimens, comprising: a plurality of specimen supports, each of the specimen supports having one of the specimens, which are different from each other, arranged thereon; a specimen driving part for moving at least one of the specimen supports; and a vibration damping mechanism for restricting a vibration of said specimen support moved by the specimen driving part, wherein the plurality of specimen supports include a first specimen support moved by the specimen driving part and a second specimen support fixed on the specimen holder, such that the second specimen support is not movable by the specimen driving part, the specimen driving part moves the first specimen support to approach to the second specimen support so as to irradiate an electron beam onto both of specimens arranged on the first specimen support and the second specimen support at the same time and to coincide focusing areas of the electron beam of both specimens with each other, the vibration damping mechanism is fixed to a second specimen support side of the specimen holder, has a flat plate-like shape, and has a contact surface contacting to an upper surface or a lower surface of the first specimen support when the first specimen support and the second specimen support are arranged in close proximity with each other, and a space is formed between the damping mechanism and the second specimen support, and the space is formed so as to coincide the focusing areas of both specimens with each other when the first specimen support and the second specimen support are arranged in close proximity with each other.
