    摘要: A method of classifying defects of an object includes irradiating multi-wavelength light onto the object, splitting light reflected from the object into light beams, each of the light beams having different wavelengths, obtaining image information of the object based on each of the light beams, forming a characteristic matrix that represent the wavelengths and the image information, and analyzing the characteristic matrix to determine types of the defects on the object. Thus, the defects may be accurately classified using a difference between reactivity of each of the defects in accordance with variations of the wavelengths and inspection conditions.

    摘要: In a method of measuring a surface voltage of an insulating layer, the number of times that surface voltages are measured in a depletion region increases so that precise data about the depletion region may be obtained. The number of times that the surface voltages are measured in an accumulation region and an inversion region decreases so that the data about the depletion region may be rapidly obtained.

    摘要: In an embodiment, a method of controlling a light intensity includes measuring a critical dimension distribution of a pattern on a substrate. The critical dimension distribution is formed using a first illumination having a first intensity distribution, which is irradiated onto the substrate through a photo mask. A second intensity distribution of the first illumination by regions of the photo mask, which is used for forming a pattern having uniform dimensions on the substrate, is then obtained based on a relation between the first intensity distribution and the critical dimension distribution. The first illumination having the first intensity distribution is converted into a second illumination having the second intensity distribution as by interposing an array of light controlling elements (e.g., LCD pixels, or motorized polarizing elements) within the light path.

    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 an embodiment, a method of scanning a substrate, and a method and an apparatus for analyzing crystal characteristics are disclosed. A sequential scan on the scan areas using a first electron beam and a second electron beam are repeatedly performed. The electrons accumulated in the scan areas by the first electron beam are removed from the scan areas by the second electron beam. When a size of the scan area is substantially the same as a spot size of the first electron beam, adjacent scan areas partially overlap each other. When each of the scan areas is larger than a spot size of the first electron beam, the adjacent scan areas do not overlap each other. Images of the scan areas are generated using back-scattered electrons emitted from each of the scan areas by irradiating the first electron beam to analyze crystal characteristics of circuit patterns on the substrate.

    摘要: Embodiments of a test pattern and a method for measuring silicon etching depth are provided. After a contact-hole forming process, an optical critical dimension (OCD) is measured with respect to a test pattern formed on a semiconductor chip, so that the silicon etching depth may be analyzed in real time. Critical dimensions of contact holes in the actual working cells of the semiconductor circuit would then coincide with the OCD measurement of the contact holes of the test pattern. Consequently, etching conditions for forming a contact hole may be controlled in real time, and thus a yield of a semiconductor can be effectively improved.
