    摘要: An overlay measuring method includes irradiating an electron beam onto a sample, including a multi-layered structure of overlapped upper and lower patterns formed thereon, to obtain an actual image of the upper and lower patterns. A first image representing the upper pattern and a second image representing the lower pattern are obtained from the actual image. A reference position for the upper and lower patterns is determined from a design image of the upper and lower patterns. A position deviation of the upper pattern with respect to the reference position in the first image and a position deviation of the lower pattern with respect to the reference position in the second image are calculated to determine an overlay between the upper pattern and the lower pattern.

    摘要: In a method of analyzing a wafer sample, a first defect of a photoresist pattern on the wafer sample having shot regions exposed with related exposure conditions is detected. A first portion of the pattern includes the shot regions exposed with an exposure condition corresponding to a reference exposure condition and a tolerance error range of the reference exposure condition. The first defect repeatedly existing in at least two of the shot regions in a second portion of the pattern is set up as a second defect of the pattern. A first reference image displaying the second defect is obtained. The first defect of the shot regions in the first portion corresponding to the second defect is set up as a third defect corresponding to weak points of the pattern. The exposure conditions of the shot region having no weak points are set up as an exposure margin of an exposure process.

    摘要: A method for inspection of defects on a substrate includes positioning a probe of a scanning probe microscopy (SPM) over and spaced apart from a substrate, includes scanning the substrate by changing a relative position of the probe with respect to the substrate on a plane spaced apart from and parallel to the substrate, and includes measuring a value of an induced current generated via the probe in at least two different regions of the substrate. The value of the induced current is variable according to at least a shape and a material of the substrate. The method further includes determining whether a defect exists by comparing the values of the induced currents measured in the at least two different regions of the substrate.

    摘要: A method of inspecting a substrate includes measuring a first current flowing between a first region and a second region of the substrate using a first probe. A second current flowing between the first region and the second region of the substrate may be measured using a second probe including a material different from that of the first probe. By comparing the first and second currents, it can be determined whether there is a change in a physical composition of the substrate and a change in a physical configuration of the substrate between the first region and the second region. Thus, when the current change is induced by the change in a physical configuration of the substrate, a determination error that the contaminants on the semiconductor substrate may exist based on the current change may be prevented.

    摘要: In a method of detecting a defect on an object, a preliminary reference image can be obtained from a plurality of comparison regions defined on the object. The preliminary reference image is divided into reference zones by a similar brightness. Each of the reference zones is provided with substantially the same gray level, respectively, to obtain a reference image. Whether a defect exists in an inspection region in the comparison regions is determined using the reference image. Thus, defects in the inspection regions having different brightnesses can be detected using the properly obtained reference image.
