  • Patent number: 10677743
    Abstract: According to an embodiment, an inspection apparatus includes an irradiation mechanism, an imaging device, a movable mechanism, and a control processor. The irradiation mechanism irradiates an inspection target with light. The imaging device captures an image of the inspection target through a lens. The movable mechanism changes, with respect to an axis extending in an inspection direction for the inspection target, an angle between the lens and a horizontal plane or an angle between the imaging device and the horizontal plane such that a sample surface of the inspection target, a principal face of the lens, and an imaging face of the imaging device conform to the Scheimpflug principle. The control processor adjusts sensitivities in an image of the sample surface captured by the imaging device at different levels in the image depending on a position in a perpendicular direction to the inspection direction.

The scanning procedure determination unit determines a procedure of scanning with a second beam for inspection on the basis of the positional information. The deflector control unit controls the deflector in such a manner that the inspection region is scanned with the second beam in a second direction in accordance with the determined scanning procedure.

  • Patent number: 8357895
    Abstract: A defect inspection method includes generating and applies a charged beam to a sample with patterns; controlling a shape of the charged beam so that a beam width in a first direction perpendicular to an optical axis differs from a beam width in a second direction perpendicular to the optical axis and the first direction, while substantially maintaining a cross-sectional area of the beam; scanning the sample with the charged beam having the controlled shape; and detecting charged particles from the sample by irradiation of the charged beam and detects a defect of the patterns. Assuming that the beam width of the charged beam in the first direction is smaller than that in the second direction, the first direction is set to a direction in which an interval between adjacent patterns becomes a minimum value and the sample is scanned in the second direction.
