    Abstract: 本发明的目的是提供一种能够配置多个试样台且至少一个试样台能够移动,并且能够利用聚焦离子束装置制作多个透射型电子显微镜用试样的电子显微镜用试样支架。在试样支架(1)的前端部设有支架前端开口部(9)。并且,在试样支架(1)的后端部具有按钮(5)、旋转机构(6)、粗调机构(7)以及连接器(8)。通过按压按钮(5)而使旋转机构(6)的固定被解除,从而从旋转机构(6)至后端部、以及试样支架的前端部进行旋转。利用本旋转机构,能够使利用透射型电子显微镜进行观察的情况和利用聚焦离子束装置制作透射型电子显微镜用试样的情况的试样的配置进行旋转。并且,能够利用粗调机构(7)及微调机构使试样台移动。

    Abstract: A grid holder (100) for STEM analysis in a charged-particle instrument has a base jaw (120) and a pivoting jaw (130). Both jaws (120, 130) have a substantially congruent inclined portion (127, 135). The base jaw (120) has a flat portion (125) for mounting the holder on the sample carousel (220) of a charged-particle instrument, such as a dual beam FIB. The inclined portion of the jaws (127, 135) is inclined to the flat portion (125) of the holder (100) at an angle A approximately equal to the difference between 90 degrees and the angle between the electron beam (260) and the ion beam (240) in the charged-particle instrument. The inclined portion (127, 135) of the jaws (120, 130) has a pocket (200) for receiving and holding a sample grid (110). When a sample is mounted on the grid (110) and the grid (1 10) is held by the grid holder (100), the sample will be correctly oriented for ion-beam thinning when the sample carousel (220) is horizontal. The thinned sample may then be placed perpendicular to the electron beam (260) for STEM analysis by tilting the sample carousel (220) by the same angle A.
