    • A single-channel optical processing system for an energetic-beam instrument has separate sources for processing radiation (170) and illumination radiation (180) that are combined in a single optical path and directed to a sample surface (140) through a selffocusing rod lens (130). The self-focusing rod lens (130) thus has a working distance from the sample surface (140) that will not interfere with typical arrangements of ion beams (100) and electron beams (110) in such instruments. A combination of polarizers (220) and beam splitters (240) allows separation of the combined incident radiation (150) and the reflected radiation (160) from the sample surface (140) and returned through the same optical channel, so that the reflected radiation (160) may be directed to an optical detector (370), such as a camera or spectrometer.
    • 用于能量束仪器的单通道光学处理系统具有用于处理辐射(170)和照射辐射(180)的单独源,其被组合在单个光学路径中并且通过光束聚焦杆透镜被引导到样品表面(140) (130)。 因此,自聚焦棒透镜(130)具有与样品表面(140)的工作距离,其不会干扰这些仪器中的离子束(100)和电子束(110)的典型布置。 偏振器(220)和分束器(240)的组合允许组合的入射辐射(150)和反射辐射(160)从样品表面(140)分离并通过相同的光学通道返回,使得反射辐射 (160)可以被引导到诸如照相机或光谱仪的光学检测器(370)。

    • An apparatus for monitoring sample milling in a charged-particle instrument has a variable-tilt specimen holder (130) attached to the instrument tilt stage (120). The variable-tilt specimen holder (130) includes a first pivoting plate (260) having a slot (280) for holding a specimen (290) rotatably supported in the variable-tilt specimen holder (130). The first pivoting plate (260) has a range of rotation sufficient to move the preferred axis of thinning of the specimen (290) from a first position where the tilt stage (120) is placed at its maximum range of tilt and the angle between the preferred axis of thinning of the specimen (290) and the axis of the ion beam column (110) of the instrument is greater than zero, to a second position where the preferred axis for thinning of the specimen (290) is substantially parallel to the axis of the ion-beam column (110). A light detector (250) is positioned to intercept light passing through the specimen (290) as it is thinned by ion-beam milling. The intensity of the light passing through the specimen (290) may be compared to the intensity recorded for previous stages of milling to determine an endpoint for milling

    • A precursor delivery system for an irradiation beam instrument having a vacuum chamber includes an injection tube (340) for injecting gasses into the vacuum chamber of the instrument and a main gas line (290) having an inlet (295) and an outlet 335). The outlet (335)is connected to the injection tube, (340) and the inlet (295) is connected to a sequential pair of valves (120, 125) connected to a carrier gas source (150). A crucible (190) for holding precursor material is selectively connected to the main gas line (290) at a location between the pair of valves (120, 125) and the injection tube (340). The source (150) of carrier gas may be selectively connected to the inlet (295) by sequential operation of the pair of carrier gas valves (120, 125), so that pulses of carrier gas assist the flow of precursor material to the injection tube (340). Rapid purging of the system between precursors is enabled by a valve (110) selectively connecting the main line (290) to an envelope (300) in communication with the instrument vacuum. Methods of CVD and etching using the system are also disclosed.
    • 用于具有真空室的辐射束仪器的前驱体输送系统包括用于将气体喷射到仪器的真空室中的喷射管(340)和具有入口(295)和出口335的主气体管线(290)。 出口(335)连接到注入管(340),并且入口(295)连接到连接到载气源(150)的顺序的一对阀(120,125)。 用于容纳前体材料的坩埚(190)在一对阀(120,125)和注入管(340)之间的位置选择性地连接到主气体管线(290)。 载气源(150)可以通过一对载气阀(120,125)的顺序操作而选择性地连接到入口(295),使得载气脉冲辅助前体材料流到注入管 (340)。 通过选择性地将主管线(290)连接到与仪器真空连通的封套(300)的阀(110)实现前体之间系统的快速清洗。 还公开了使用该系统的CVD和蚀刻方法。
