    Abstract: In a method of inspecting defects, a first actual region of an actual object is inspected based on a first characteristic parameter as an inspection condition. A point where an inspection region of the actual object is changed into a second actual region from the first actual region is determined. The second actual region is then inspected based on a second characteristic parameter as the inspection condition. The first and second parameters may include contrast of a light that is reflected from a reference object, intensity of the light, brightness of the light, a size of a minute structure on the reference object, etc. The characteristic parameters of each reference region on the reference object are set. Thus, the defects may be accurately classified so that a time and a cost for reviewing the defects may be markedly reduced.

    Abstract: In a method for inspecting a defect in accordance with one aspect of the present invention, an object is divided into a plurality of regions. Reflectivity of each of the plurality of regions is obtained. Amplification ratio for each region is determined using the reflectivity. A light is irradiated onto the regions. A light reflected from a first region is amplified by a first amplification ratio that is determined for the first region. Moving the irradiated light from the first region to a second region is detected. A light reflected from the second region is amplified by a second amplification ratio that is determined for the second region. The amplified lights from the first region and the second region are analyzed to determine an existence of a defect on the object.

    Abstract: 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.

    Abstract: In an embodiment of a method of inspecting a substrate, the substrate on which minute structures are formed is divided into a plurality of inspection regions. A main inspection region among the inspection regions is selected. A main image of the main inspection region and sub-images of sub-inspection regions adjacent to the main inspection region are obtained. An average image of the main image and the sub-images is obtained. The average image is then compared with the main image to detect defects in the main inspection region. Gray levels may be used. The average image may have improved quality so that the defects in the selected inspection region may be rapidly and accurately detected. This process has an improved reliability. Further, the number of inspecting processes for the substrate may be reduced. And a line for the inspection process may be automated so that a worker-free line may be established.

    Abstract: The present invention is directed to a wafer holder and a related wafer conveyor system. The wafer holder holds a wafer and moves horizontally within a chamber. A contact area between the wafer and the wafer holder is reduced, and potential contaminants generated by ear between components of the wafer holder are trapped by an airtight cover. Since the wafer holder moves horizontally while being fixed to a guide rail, the wafer conveyor system reduces friction between the guide rail and the wafer holder.

    Abstract: A system and method of measuring a distance of semiconductor patterns is provided. The system includes a microscope and a control unit. The control unit calculates standard coordinates of standard points in view-fields that include spots, spot coordinates of spots with respect to standard points, real coordinates of spots from both of the standard coordinates and spot coordinates, and finally the distance between the two spots from the first and second real coordinates. Coordinates are determined using high magnification, in conjunction with pixel counting, allowing more precise distance measurements.

    Abstract: An apparatus and method of measuring the thickness of a substrate. A first light is reflected from a standard sample having a known thickness. The light is concentrated through the light-focusing lens. The first light is converted into a first electrical signal by a detector responding to a light intensity of the concentrated first light. A second light is reflected from a substrate, and then is concentrated through the light-focusing lens. The second light is converted into a second electrical signal by the detector responding to a light intensity of the concentrated second light. An operating unit determines first and second peak values from the first and second electrical signals, respectively. The operating unit calculates the thickness of the substrate by using a standard distance corresponding to the first peak value, a moving distance of the substrate corresponding to the second peak value, and the known thickness of the standard sample.
