  • Patent number: 8327144
    Abstract: The present invention provides an authentication method for inter-domain information communication applied to first and second domains. The method instructs a first electronic device belonging to the first domain to request, through an intermediary node device simultaneously registered in the first and second domains, to obtain a first key from a second key distribution center in the second domain for transmission to a second electronic device in the second domain, and instructs the second electronic device to request, through the intermediary node device, to obtain a second key from a first key distribution center in the first domain for transmission to the first electronic device. Therefore, the first and second electronic devices are instructed to generate a shared third key using the first and second keys to perform secure information communication authentication.

  • Publication number: 20120273678
    Abstract: A method for examining a sample with a scanning charged particle beam imaging apparatus. First, an image area and a scan area are specified on a surface of the sample. Herein, the image area is entirely overlapped within the scan area. Next, the scan area is scanned by using a charged particle beam along a direction neither parallel nor perpendicular to an orientation of the scan area. It is possible that only a portion of the scan area overlapped with the image area is exposed to the charged particle beam. It also is possible that both the shape and the size of the image area are essentially similar with that of the scan area, such that the size of the area projected by the charged particle beam is almost equal to the size of the image area.

  • Publication number: 20120212601
    Abstract: A method for measuring critical dimension (CD) includes steps of: scanning at least one area of interest of a die to obtain at least one scanned image; aligning the scanned image to at least one designed layout pattern to identify a plurality of borders within the scanned image; and averaging distances each measured from the border or the plurality of borders of a pattern associated with a specific type of CD corresponding to the designed layout pattern to obtain a value of CD of the die. The value of critical dimensions of dies can be obtained from the scanned image with lower resolution which is obtained by relatively higher scanning speed, so the above-mentioned method can obtain value of CD for every die within entire wafer to monitor the uniformity of the semiconductor manufacturing process within an acceptable inspection time.
