  • Patent number: 9373480
    Abstract: In a SEM device which enables observations under an atmospheric pressure, in the event that a diaphragm is damaged during an observation of a sample, air flows into a charged particle optical barrel from the vicinity of the sample, due to the differential pressure between the inside of the charged particle optical barrel under vacuum and the vicinity of the sample under the atmospheric pressure. At this time, the sample may be sucked into the charged particle optical barrel. In this case, a charged particle optical system and a detector are contaminated thereby, which causes performance degradation or failures of the charged particle microscope. For coping therewith, it is necessary to prevent the charged particle optical barrel from being contaminated, without inducing a time lag, with a simple structure.

  • Publication number: 20160141682
    Abstract: An object is to maintain the voltage of a fuel cell at a desired voltage level and suppress a voltage variation, even in the case of a low load request. A power supply system including a fuel cell causes at least part of a required electric power to be supplied from the fuel cell in an ordinary load state. In a low load state, the power supply system supplies an amount of oxygen that is required to make the voltage of the fuel cell equal to a predetermined target voltage and that is less than an amount of oxygen supplied to the fuel cell in the ordinary load state, to the fuel cell. In a first low load state, the power supply system sets the target voltage to a first target voltage and supplies oxygen to the fuel cell.

  • Patent number: 9321085
    Abstract: A chemical liquid process is performed on a substrate. Then, a rinse process that supplies a rinse liquid to the substrate is performed. Thereafter, a drying process that dries the substrate is performed while rotating the substrate. The drying process includes a first drying process that rotates the substrate at a first rotational speed; a second drying process that decreases the rotational speed of the substrate to a second rotational speed lower than the first rotational speed after the first drying process. In the second drying process, the rinse liquid and a drying solution are agitated and substituted while generating braking effect. In a third drying process, the rotational speed of the substrate is increased from the second rotational speed to a third rotational speed after the second drying process. Thereafter, in a fourth drying process, the drying solution on the substrate is scattered away by rotating the substrate.

  • Patent number: 9251996
    Abstract: In a charged particle beam device that performs observation of a sample under a gas environment in atmospheric pressure or pressure substantially equal to the atmospheric pressure, a diaphragm that separates an atmospheric pressure space, in which the sample is placed, and a vacuum space in an interior of an electron optical lens barrel is made very thin in order to allow an electron beam to transmit therethrough and damaged with a high possibility. Although at the time of replacing the diaphragm, it is necessary to adjust a position of a diaphragm, it is impossible to easily perform the adjustment of the position of the diaphragm by a conventional method.

  • Patent number: 9240305
    Abstract: All of the conventional charged particle beam devices are designed only for the observation at atmospheric pressure or in gas atmosphere at a pressure substantially equal to the atmospheric pressure, and there is no device enabling easy observation using a typical high-vacuum charged particle microscope at atmospheric pressure or in gas atmosphere at a pressure substantially equal to the atmospheric pressure. Such a conventional technique has another problem that the distance between the diaphragm and a sample cannot be controlled, and so it has a high risk of breakage of the diaphragm.
