  • Patent number: 7301146
    Abstract: A probe driving method and a probe apparatus for bringing a probe into contact with the surface of a sample in a safe and efficient manner by monitoring the probe height. Information about the height of the probe from the sample surface is obtained by detecting a probe shadow (54) appearing immediately before the probe contacts the sample, or based on a change in relative positions of a probe image and a sample image that are formed as an ion beam is irradiated diagonally.

  • Patent number: 7266235
    Abstract: A pattern inspection method in which an image can be detected without an image detection error caused by an adverse effect to be given by such factors as ions implanted in a wafer, pattern connection/non-connection, and pattern edge formation. A digital image of an object substrate is attained through microscopic observation thereof, the attained digital image is examined to detect defects, while masking a region pre-registered in terms of coordinates, or while masking a pattern meeting a pre-registered pattern, and an image of each of the defects thus detected is displayed. Further, each of the defects detected using the digital image attained through microscopic observation is checked to determine whether its feature meets a pre-registered feature or not. Defects having a feature that meets the pre-registered feature are so displayed that they can be turned on/off, or they are so displayed as to be distinguishable from the other defects.

  • Patent number: 7260256
    Abstract: The present invention relates to detection of defects with simple specification of the coordinates, in the inspection of an object having a plurality of patterns in which a portion having the two-dimensional repetition and portions having the repetition only in the X direction and in the Y direction are mixedly present. The cross comparison between a notice point and comparison points, for example which are repetitive pitches away from the notice point, is carried out, and only the portion having the difference which can be found out with any of the comparison points is extracted as a defect candidate, which results in that the portion having the two-dimensional repetition as well as the portion having the repetition only in the X direction or in the Y direction can be inspected.

    Abstract: An inspection method and apparatus includes control of an acceleration voltage of an electron beam, irradiation of the electron beam to an object to be inspected mounted on a stage which is continuously moving at least in one direction, and detection of at least one of secondary electrons and reflected electrons emanated from the object in response to the irradiation. An image of the object is obtained from the detected electron by using positional information of the stage and inspection or measurement of the object is conducted using and obtained image. In the detection, an electric field in the vicinity of the object mounted on the stage is controlled so that at least one secondary electrons and the reflected electrons emanated from the object in response to the irradiation of the electron beam are decelerated.

  • Patent number: 7026830
    Abstract: To make possible the in-line inspection of a pattern of an insulating material. A patterned wafer 40 formed with a pattern by a resist film is placed on a specimen table 21 of a patterned wafer inspection apparatus 1 in opposed relation to a SEM 3. An electron beam 10 of a large current is emitted from an electron gun 11 and the pattern of the patterned wafer is scanned only once at a high scanning rate. The secondary electrons generated by this scanning from the patterned wafer are detected by a secondary electron detector 16 thereby to acquire an electron beam image. Using this electron beam image, the comparative inspection is conducted on the patterned wafer through an arithmetic operation unit 32 and a defect determining unit 33. Since an electron beam image of high contrast can be obtained by scanning an electron beam only once, a patterned wafer inspection method using a SEM can be implemented in the IC fabrication method.
