  • Publication number: 20090208091
    Abstract: A degradation in throughput is prevented even in cases where it is necessary to reduce a pixel size during inspection according to a finer circuit pattern. In an inspection method and an inspection apparatus in which an inspected sample having a circuit pattern is irradiated with a charged particle beam to generate a signal, an image is obtained from the signal, and in which a defect of the circuit pattern is detected from the image, the inspection is performed while an inspected pixel size in a direction in which the charged particle beam is scanned relative to the inspected sample and an inspected pixel size in a stage moving direction are separately set. The stage is moved while the inspected sample is placed thereon.

  • Publication number: 20070114397
    Abstract: The via chain conduction failure due to non-conduction caused by insufficient etching in a contact plug/via plug forming process can be detected precisely in a short time. For its achievement, a defect is detected at high speed by taxing advantage of characteristics of a potential contrast method using a via chain defect inspection structure and an electron beam defect detection apparatus which can perform continuous inspection while changing an inspection direction without rotating a wafer. Accordingly, the capturing efficiency of a critical electric defect and search efficiency of a defect point can be improved.
