  • Patent number: 8835872
    Abstract: A sample stage device (10) is so configured as to calculate ideal position information xtg(i), tg(i) per predetermined period that is unaffected by drive conditions relating to gaps (25, 26), etc., and to determine, per predetermined cycle and in real time, deviations dx(i), dy(i) between real-time measured positions x(i), y(i) by position detectors comprising laser interferometers (33, 34), etc., and ideal position information xtg(i), tg(i). In addition, it calculates, based on deviations dx(i), dy(i) thus determined, such speed command values vx(i), vy(i) for motors (27, 28) that measured values x(i), y(i) would follow ideal position information xtg(i), tg(i), and performs stable and high-speed positioning control for a sample table (11) through feedback control that controls speed in real time.

A spherical housing receives the spherical bearing and allows the bearing to rotate therein. The housing and bearing may form an air bearing. A seal may be formed in the housing to prevent gas from the air bearing and the ambient atmosphere from migrating to a process chamber side of the housing. A set of spherical air pads may be positioned on an ambient side of the bearing to press the bearing against the housing when the process chamber is not under vacuum conditions. The seal can include a set of differentially pumped grooves. The spherical bearing enables the wafer manipulation end, and a wafer attached thereto, to be moved with four degrees of freedom. The arrangement facilitates isocentric scanning of a workpiece. Methods for using the assembly are also disclosed.

Via the through-hole, gas evaporating or volatilizing from the vessel is supplied to the sample under observation, thereby creating a localized low-vacuum state at or in the vicinity of the sample.

    Abstract: The present invention relates to a specimen box for an electron microscope, which comprises a first substrate, a second substrate, and a metal adhesion layer. The first substrate has a first surface, a second surface, a first concave, and one or more first through holes, wherein the first through hole penetrates through the first substrate. The second substrate has a third surface, a forth surface, and a second concave. Besides, the metal adhesion layer is disposed between the first substrate and the second substrate to form a space for a specimen placed therein. In addition, the specimen box of the present invention further comprises one or more plugs.

  • Patent number: 8563945
    Abstract: In various embodiments of the invention, a cargo container can be monitored at appropriate time intervals to determine that no controlled substances have been shipped with the cargo in the container. The monitoring utilizes reactive species produced from an atmospheric analyzer to ionize analyte molecules present in the container which are then analyzed by an appropriate spectroscopy system. In an embodiment of the invention, a sorbent surface can be used to absorb, adsorb or condense analyte molecules within the container whereafter the sorbent surface can be interrogated with the reactive species to generate analyte species characteristic of the contents of the container.

  • Patent number: 8536540
    Abstract: Since charging characteristics differ between the outer circumferential portion and the center portion of a sample to be inspected, equivalent inspection sensitivities cannot be obtained in the outer circumferential portion and the center portion of the sample to be inspected. A sample cover is provided in the outer circumferential portion of a sample holder on which the sample to be inspected is placed. Charging characteristics of the sample cover are changed according to charging characteristics of the sample to be inspected. Consequently, uniform charged states can be formed in the outer circumferential portion and the center portion of the sample. Inspection/observation of the outer circumferential portion of the sample can be realized at higher sensitivity than in the past.

    Abstract: A method for adjusting an operating parameter of a particle beam device and a sample holder, which is suitable in particular for performing the method are provided. An adjustment of an operating parameter of a particle beam device is possible without transfer of the sample holder out of the particle beam device. A reference sample is placed in a first sample receptacle, so that in ongoing operation of the particle beam device, the sample holder need only be positioned in such a way that the reference sample is bombarded and measured with the aid of a particle beam generated in the particle beam device.

  • Patent number: 8519332
    Abstract: In the case of inspecting samples having different sizes by means of a semiconductor inspecting apparatus, a primary electron beam bends since distribution is disturbed on an equipotential surface at the vicinity of the sample at the time of inspecting vicinities of the sample, and what is called a positional shift is generated. A potential correcting electrode is arranged outside the sample and at a position lower than the sample lower surface, and a potential lower than that of the sample is applied. Furthermore, a voltage to be applied to the potential correcting electrode is controlled corresponding to a distance between the inspecting position and a sample outer end, sample thickness and irradiation conditions of the primary electron beam.

  • Patent number: 8513622
    Abstract: A method for attaching a frozen specimen to a manipulator probe tip typically inside a charged-particle beam microscope. The method comprises cooling the probe tip to a temperature at or below that of the frozen specimen, where the temperature of the frozen specimen is preferably at or below the vitrification temperature of water; bringing the probe tip into contact with the frozen specimen, and bonding the probe tip to the frozen specimen by flowing water vapor onto the region of contact between the probe tip and the frozen specimen. The bonded probe tip and specimen may be moved to a support structure such as a TEM grid and bonded to it by similar means. The probe tip can then be disconnected by heating the probe tip or applying a charged-particle beam.
