    摘要: Disclosed is an aberration measurement method of a charged particle beam device provided with an aberration corrector (4). The method is characterized by: when measuring aberration, (A) the number of pixels or the resolution is changed of a first image and a second image that are benchmarks when measuring field of view offset, and after determining the destination of movement resulting from a rough field of view offset, the number of pixels or the resolution of the first image and the second image are set to the same conditions, and the amount of field of view offset is measured precisely, or (B) a sample having lines in the horizontal direction and in the vertical direction is one-dimensionally scanned, and the amount of movement is measured from the signal position offset. As a result, in a charged particle beam device provided mounted with an aberration corrector, it becomes possible to provide a highly precise aberration measurement method that is not to the detriment of measurement time.

    摘要: An exhaust manifold is covered by a manifold heat shield cover and an exhaust pipe is directed downward from the exhaust manifold. In such an engine, a cooling fan is disposed on a front portion of the engine and the exhaust pipe is positioned on the air flow path of the cooling fan. An auxiliary component heat shielding plate is directed from the manifold heat shield cover along a back side of the exhaust pipe. An auxiliary engine component is disposed beneath the manifold heat shield cover on a back side of the auxiliary component heat shielding plate. Between the exhaust pipe and a cylinder block, an air flow guide plate provides an air flow space between the air flow guide plate and the cylinder block. A cooling air flow passing through the air flow space is thus supplied to the auxiliary engine component.

    摘要: The present invention provides a stable charged particle beam apparatus to enable high-resolution observation by reducing the influence of the noise of a large number of power supplies used in an aberration corrector. The charged particle beam apparatus that has: an SEM column for irradiating an electron beam onto a specimen and making the electron beam scan it; a specimen chamber for housing a specimen stage on which the specimen is placed and held; a detector for detecting secondary electrons generated by the scanning of the electron beam; display means for displaying an output signal of the detector as an SEM image; and a control unit for controlling component parts including the SEM column, the specimen chamber, and the display means. The SEM column has a pair of accelerating electrodes and an aberration corrector that is placed between the pair of accelerating electrodes and corrects aberration of the electron beam, and accelerates the electron beam during a period when being transmitted through the aberration corrector by a high voltage being impressed across the pair of accelerating electrodes.
