  • Patent number: 8270703
    Abstract: A distinguishing size for distinguishing a pseudo defect from a defect caused by a process trouble is stored in a first storage area. Defect data are stored in a second storage area. A processing unit detects a defect on a wafer surface, and stores the defect data in the second storage area. Before a defect detection process is completed for all areas of the wafer surface, a size of a defect detected in a partial area is compared with the distinguishing size stored in the first storage area. If the detected defect has a size equal to or larger than the distinguishing size, an alarm is output through an output unit, whereas if a defect having a size equal to or larger than the distinguishing size is not detected, the defect detection process is executed for the area still not subjected to the defect detection process.

  • Patent number: 7948618
    Abstract: Scattered light from the surface of a sample subjected to the same process as a process for an inspection object is observed, a defect is detected from an intensity of scattered light, and a position of the detected defect and an intensity of scattered light caused by the detected defect are acquired. Defects detected are classified into a group detectable by observing secondary electrons emitted when an electron beam is applied to the surface of the sample and a group not detectable. A decision threshold value of a scattered light intensity for extracting defects to be counted is determined, in accordance with a result of classification by the above steps and the intensity of scattered light caused by the detected defect.
