    摘要: In a method and an apparatus for inspecting a wafer surface, a wafer is loaded into a chamber. An incident light including a first light for sensing a vertical position of the wafer and a second light for inspecting the wafer surface is irradiated onto the wafer. The first light is reflected on an inspection region or a next inspection region of the wafer and is detected to control a wafer position. The second light is scattered on the inspection region and is detected to inspect the wafer surface of the inspection region. Position information of a wafer is examined and a position of the wafer is adjusted before inspecting a surface of inspection region of a wafer so as to enable accurate inspection of the wafer surface.

    摘要: 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.

    摘要: An apparatus for measuring contamination of a semiconductor substrate includes a chuck for loading a substrate, a position detection means for recognizing a front surface of the loaded substrate to obtain position data of a portion of the substrate to be measured, a first driving part for moving the chuck in accordance with the position data to measure a rear portion of the substrate, and a surface measurement means disposed under the chuck for selectively measuring metal contamination of the substrate at the rear portion of the substrate. In operation, the substrate is loaded onto a chuck, position data of a portion of the substrate to be measured is obtained by recognizing patterns formed on the substrate, the substrate is then moved in accordance with the position data to measure a rear portion of the substrate, and metal contamination is selectively measured at the rear portion of the substrate.

    摘要: 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.
