  • Publication number: 20110284745
    Abstract: A sample holder, inspection apparatus, and an inspection method using the sample holder having a film including a first surface and a second surface. A liquid sample may be held on the first surface. The film is made of two or more layers. A primary beam irradiation device is installed in a reduced-pressure space. Consequently, the sample can be observed or inspected while maintaining the sample at the atmospheric pressure.

  • Patent number: 8030622
    Abstract: A specimen holder is offered which can reduce the amount of chemical sprayed over a specimen consisting of cultured cells. The specimen holder has an open specimen-holding surface. At least a part of the specimen-holding surface is formed by a film and a tapering portion formed around the film. The specimen can be cultured on the specimen-holding surface of the film. The presence of the tapering portion can reduce the amount of used reagent. The specimen can be irradiated via the film with a primary beam for observation or inspection of the specimen. Consequently, the specimen, such as cells, can be well observed or inspected in vivo while the specimen is being cultured. Especially, if an electron beam is used as the primary beam, the specimen can be well observed or inspected in vivo by SEM (scanning electron microscopy).

  • Patent number: 7928380
    Abstract: A sample holder used in SEM (scanning electron microscopy) or TEM (transmission electron microscopy) permitting observation and inspection at higher resolution. The holder has a frame-like member provided with an opening that is covered with a film. The film has a first surface on which a sample is held. The thickness D of the film and the length L of the portion of the film providing a cover over the opening in the frame-like member satisfy a relationship given by L/D <200,000.

  • Patent number: 7906760
    Abstract: An electron microscope method for inspecting a liquid specimen and a reagent solution therefor. A culture medium and biological cells are put in the sample holder. A plugging agent is mixed into the liquid sample. The cells can be irradiated with a primary beam via a film. An image of the cells or information about the cells is obtained by detecting a resulting secondary signal. If the film is destroyed, the plugging agent plugs up the damaged portion of the film. Consequently, liquid leakage can be minimized.

  • Patent number: 7876113
    Abstract: Electron beam is irradiated to a wafer in the midst of steps at predetermined intervals by a plurality of times under a condition in which a junction becomes rearward bias and a difference in characteristic of a time period of alleviating charge in the rearward bias is monitored. As a result, charge is alleviated at a location where junction leakage is caused in a time period shorter than that of a normal portion and therefore, a potential difference is produced between the normal portion and a failed portion and is observed in a potential contrast image as a difference in brightness. By consecutively repeating operation of acquiring the image, executing an image processing in real time and storing a position and brightness of the failed portion, the automatic inspection of a designated region can be executed. Information of image, brightness and distribution of the failed portion is preserved and outputted automatically after inspection.

  • Publication number: 20100243888
    Abstract: An inspection apparatus and method capable of well observing or inspecting a specimen contained in a liquid. The inspection apparatus has a film including first and second surfaces. Furthermore, the apparatus has a vacuum chamber for reducing the pressure in the ambient in contact with the second surface of the film, primary beam irradiation column connected with the vacuum chamber, and a shutter for partially partitioning the space between the film and the primary beam irradiation column within the vacuum chamber. A liquid sample is held on the first surface of the film. The primary beam irradiation column irradiates the sample. Backscattered electrons (a secondary beam) produced from the sample by the primary beam irradiation are directed at the shutter, producing secondary electrons (a tertiary signal).

  • Publication number: 20100019146
    Abstract: Specimen holder, specimen inspection apparatus, and specimen inspection method for observing or inspecting a specimen consisting of cultured cells. The specimen holder has a body portion and a film. The body portion has a specimen-holding surface opened to permit access from the outside. The film has a first surface forming the specimen-holding surface. The specimen disposed on the first surface of the film can be irradiated with a primary beam for observation or inspection of the specimen via the film. A region coated with an electrically conductive film is formed on the bottom surface of the body portion facing away from the specimen-holding surface. An optically transparent region not coated with the electrically conductive film is also formed on the bottom surface.

  • Patent number: 7202476
    Abstract: A charged-particle beam instrument is offered which can inspect side and rear surfaces of a sample. Two electron optical microscope columns are mounted in a vacuum chamber. Each of the microscope columns has an electron gun, a condenser lens system, a deflector, and a secondary electron detector. A sample stage assembly on which a sample is placed is mounted in the vacuum chamber. The stage assembly consists of a rotary stage, an X-stage, and a Y-stage. One of the microscope columns is placed in a position where the electron beam from the column can scan at least an upper part of a side surface of the sample.
