  • Patent number: 10133052
    Abstract: An image acquiring method for acquiring an image using a measurement apparatus including an image acquiring means which acquires an image of a surface of a target to be measured in the unit of predetermined size pixels and a moving means capable of moving the target to be measured, the image acquiring method includes: acquiring an image of a first region from the surface of the target to be measured through the image acquiring means; acquiring an image of a second region, which is different from the first region, by moving the target to be measured, through the moving means; acquiring a differential image by subtracting, from either the image of the first region or the image of the second region, the other image; and overlapping the differential image multiple times.

  • Patent number: 9645169
    Abstract: A measurement method in which a sensing unit acquires surface data of a measurement target while scanning the surface of the measurement target and at least one of the sensing unit and the measurement target is moved in order for the sensing unit to scan the surface along a plurality of fast scan lines on the surface of the measurement target, includes: a first step in which the sensing unit scans a surface along any one fast scan line of the plurality of fast scan lines to acquire the surface data along the any one fast scan line; and a second step in which the sensing unit acquires a surface data along a fast scan line most adjacent to the any one fast scan line while at least one of the sensing unit and the measurement target is moved along the most adjacent fast scan line, after the first step.

  • Patent number: 9081272
    Abstract: The present invention relates to a leveling apparatus that levels an object to be leveled with a surface of a substrate by measuring the force applied to the object, and an atomic force microscope including the leveling apparatus. A leveling apparatus according to the present invention, which levels an object with a substrate such that one side of the object is brought in parallel contact with the surface of the substrate, includes: force sensors disposed to measure force at at least three points on the other side of the object; an angle adjusting unit disposed to adjust the angle between the object and the surface of the substrate; and a controller connecting with the force sensors and the angle adjusting unit to drive the angle adjusting unit on the basis of data from the force sensors.
