  • Publication number: 20120128286
    Abstract: A sliding bearing 4 is formed in the shape of a cylinder by joining joining surfaces 11A and 12A of a pair of half bearings 11 and 12 together. A through hole 7 is formed in the position of the joining surfaces 11A and 12A in such a manner that the through hole 7 coincides with the trajectory of movement of a lubrication hole 3A in a crankpin 3. A foreign particle discharge groove 8 is formed in an outer circumferential surface of the sliding bearing 4 along the axial direction leading from the through hole 7. When the crankpin 3 is rotated, a lubricant is directly supplied into the through hole 7 as well through the lubrication hole 3A. Foreign particles 15 contained in the lubricant pass through the through hole 7 and are then discharged to the outside the sliding bearing 4 through the foreign particle discharge groove 8. Thus, a sliding bearing 4 that can smoothly discharge foreign particles can be provided.

  • Publication number: 20120074316
    Abstract: An electro-optical inspection apparatus is provided that is capable of preventing adhesion of dust or particles to the sample surface as much as possible. A stage (100) on which a sample (200) is placed is disposed inside a vacuum chamber (112) that can be evacuated to vacuum, and a dust collecting electrode (122) is disposed to surround a periphery of the sample (200). The dust collecting electrode (122) is applied with a voltage having the same polarity as a voltage applied to the sample (200) and an absolute value that is the same or larger than an absolute value of the voltage. Thus, because dust or particles such as particles adhere to the dust collecting electrode (122), adhesion of the dust or particles to the sample surface can be reduced. Instead of using the dust collecting electrode, it is possible to form a recess on a wall of the vacuum chamber containing the stage, or to dispose on the wall a metal plate having a mesh structure to which a predetermined voltage is applied.

  • Publication number: 20120062890
    Abstract: Conventionally, a particle/defect inspection apparatus outputs a total number of detected particles/defects as the result of detection. For taking countermeasures to failures in manufacturing processes, the particles/defects detected by the inspection apparatus are analyzed. Since the inspection apparatus outputs a large number of detected particles/defects, an immense time is required for analyzing the detected particles/defects, resulting in a delay in taking countermeasures to a failure in the manufacturing processes. In the present invention, an apparatus for optically inspecting particles or defects relates a particle or defect size to a cause of failure in an inspection result. A data processing circuit points out a cause of failure from the statistics on the inspection result, and displays information on the inspection result.

  • Publication number: 20120049063
    Abstract: The present invention provides a surface inspection method and apparatus for inspecting a surface of a sample, in which a resistive film is coated on the surface, and a beam is irradiated to the surface having the resistive film coated thereon, to thereby conduct inspection of the surface of the sample. In the surface inspection method of the present invention, a resistive film having an arbitrarily determined thickness t1 is first coated on a surface of a sample. Thereafter, a part of the resistive film having the arbitrarily determined thickness t1 is dissolved in a solvent, to thereby reduce the thickness of the resistive film to a desired level. This enables precise control of a value of resistance of the resistive film and suppresses distortion of an image to be detected.

  • Patent number: 8124933
    Abstract: An apparatus capable of detecting defects of a pattern on a sample with high accuracy and reliability and at a high throughput, and a semiconductor manufacturing method using the same are provided. The electron beam apparatus is a mapping-projection-type electron beam apparatus for observing or evaluating a surface of the sample by irradiating the sample with a primary electron beam and forming on a detector an image of reflected electrons emitted from the sample. An electron impact-type detector such as an electron impact-type CCD or an electron impact-type TDI is used as the detector for detecting the reflected electrons. The reflected electrons are selectively detected from an energy difference between the reflected electrons and secondary electrons emitted from the sample.
