  • Publication number: 20070285653
    Abstract: (a) 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 scatted light, and a position of the detected defect and an intensity of scattered light caused by the detected defect are acquired. (b) Defects detected at the step (a) 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. (c) 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 step (b) and the intensity of scattered light caused by the detected defect.

  • Publication number: 20070255513
    Abstract: An inspecting method is capable of efficiently inspecting a wafer. According to the inspecting method, the chip area of a wafer is inspected for defects, and based on the results, a defect density D0p of each of peripheral-zone chips in the chip area which are located closely to the peripheral area of the wafer is calculated. A peripheral-zone chip with a high defect density D0p is selected, and an area in the peripheral area which is outward of the selected peripheral-zone chip is inspected for defects. Since only the area in the peripheral area which is located outward of the peripheral-zone chip selected based on the defect density D0p is inspected for defects, the wafer is inspected efficiently.

  • Publication number: 20070230769
    Abstract: A first defect classification section uses a pre-inspection test target as the inspected piece, and classifies the defects, based on results of the defect inspection executed a plurality of times by the defect detection system, into first defects detected constantly in each of the plurality of times of inspection, and into second defects detected only in a part of, but not in the residual part of the plurality of times of inspection.

  • Patent number: 7064820
    Abstract: A surface inspection method in a surface inspection system which comprises a photodetection unit and a photodetection polarizing angle changing means, comprising the step of receiving a scattered reflection light from a substrate surface where standard particles are coated by changing a photodetection polarizing angle by the photodetection polarizing angle changing means, and the step of performing surface inspection by setting the photodetection polarizing angle to a condition where an S/N ratio of photodetection output is at the highest.

  • Publication number: 20060056676
    Abstract: Disclosed is a surface inspection device that performs a defect inspection throughout a surface of a wafer. In the defect detection using a defect review SEM, an X-Y coordinate system is set throughout a surface (excluding a round end face) of a product wafer to allow the inspection throughout the surface of the product wafer. Therefore, the defect detection can be performed also in an area other than an effective chip area. Further, the inspection results of the area are stored in relation to the coordinates in a position where the inspection results are acquired. Therefore, the inspection results can be effectively used for an analysis and a defect cause can be investigated with a higher degree of accuracy. As a result, the quality and yield of chips can be improved.

  • Patent number: 6386577
    Abstract: A module case having an air bag module accommodated therein is disposed in a side face of a seat back, so that a lid of the module case is opened by a pressure of an air bag expanded upon a side collision of a vehicle, and the air bag is deployed through the resulting opening, termed the “primary” opening into a vehicle compartment. As a result of a tear line provided in the module case, even if the lid is held down by the door which has been deformed by a shock resulting from the collision, so that the lid cannot be opened to provide the primary opening, the tear line in a case body of the module case is broken, whereby a front wall is pivoted forwardly to form an alternate or “secondary” opening from the module case. Therefore, the air bag can be deployed without hindrance through the alternate secondary opening defined in the front wall of the module case into the vehicle compartment.
