Publication number: 20070285653Abstract: (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.Type: ApplicationFiled: October 16, 2006Publication date: December 13, 2007Applicant: FUJITSU LIMITEDInventors: Naohiro Takahashi, Tamihide Yasumoto, Tadamasa Noguchi

Publication number: 20070255513Abstract: 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.Type: ApplicationFiled: October 27, 2006Publication date: November 1, 2007Applicant: FUJITSU LIMITEDInventors: Naohiro Takahashi, Kiyoshi Irino

Publication number: 20060056676Abstract: 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.Type: ApplicationFiled: February 16, 2005Publication date: March 16, 2006Applicant: FUJITSU LIMITEDInventor: Naohiro Takahashi

Patent number: 6386577Abstract: 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.Type: GrantFiled: March 23, 2000Date of Patent: May 14, 2002Assignee: Honda Giken Kogyokabushiki KaishaInventors: Makoto Kan, Takashi Honda, Naotoshi Takemura, Takashi Aoki, Tatsuya Terauchi, Naohiro Takahashi
