  • Patent number: 7538868
    Abstract: Calibration of pattern recognition in bright field imaging systems is disclosed. A target pattern on a substrate on the stage is brought into focus of a bright field system. The image is scanned in a first direction while measuring an edge scattering pattern from a feature of the target pattern. The edge scattering pattern is characterized by first and second peaks. A position of the bright field system's illuminator or beam shaping and relay optics is adjusted perpendicular to an optical path until the first and second peaks are approximately equal in height.

  • Publication number: 20080129988
    Abstract: Various methods and systems for identifying defect types on a wafer are provided. One computer-implemented method for identifying defect types on a wafer includes acquiring output of an inspection system for defects detected on a wafer. The output is acquired by different combinations of illumination and collection channels of the inspection system. The method also includes identifying defect types of the defects based on the output acquired by a set of the different combinations. The set of the different combinations is selected based on the defect types to be identified on the wafer and a wafer type of the wafer such that a different set of the different combinations of the illumination and collection channels is used for identifying different defect types on different wafer types.

  • Patent number: 6442279
    Abstract: An acoustic conditioning apparatus. The mechanism includes an attenuator to limit excessive noise levels. The attenuator includes a circuit for compressing an output sound pressure level below a desired level, such as 90 dBA over an eight-hour period. The mechanism also includes an amplifier for conditioning ambient sound level in accordance with the normal needs of a hearing impaired person using the conditioning apparatus. Additionally included is a switch in an electrical circuit to enable selection of attenuation of excessive noise levels or normal amplification. The switch can be controlled either manually by means of a toggle on a housing enclosing the various components, or automatically in response to the sensed noise level.

  • Publication number: 20020044650
    Abstract: An identity credence and a method for producing the same are provided in the present invention. In order to produce the identity credence, the issuing organ firstly constructs a first information packet which comprises identity information and biometrics information; then selects an asymmetric encryption algorithm for digital ciphering on the first information packet with a private key to generate a second information packet; and finally stores the second information packet generated by ciphering into a medium to produce an identity credence.

  • Publication number: 20010023375
    Abstract: A fingerprint hard disk has been provided in the present invention. Said fingerprint hard disk comprises a fingerprint identifier for identifying whether the user's fingerprint is qualified, wherein said fingerprint identifier includes a control interface for issuing a control signal according to the identification result of the fingerprint identifier; and comprises a hard disk including a hard disk body and a hard disk control device which is used to receive a control signal issued by the control interface of the fingerprint identifier to control the operating state of the hard disk body. The fingerprint identifier and the hard disk are combined organically; and the fingerprint of a specific user may be recorded in advance as required, and then, by identifying the fingerprint, only said specific user will be allowed to open the hard disk and read the data.
