摘要： Disclosed is a method for requesting for location information of resources on a P2P network, user node and server for the same, which allow a user to get network resources quickly. The popular files and the unpopular files are managed separately. The metadata of popular files are stored a plurality of SN based on respective areas, while the metadata of the unpopular files are stored and queried in a centralized manner. A function of redirecting a request message is added into the SN so as to inform the user the existence of a SN-R. Meanwhile, in order to improve query efficiency and avoid repeatedly redirecting of the message, a server routing table is provided for the user node which can indicate which files need to be download and which server should be requested to provide the files. Due to the popular filed and the unpopular filed are stored separately and all of unpopular files are stored in a centralized manner, the user can get unpopular files when the user request for the unpopular files in a P2P network.

摘要： A method of collating and using captured semiconductor-wafer image data in an automated defect analysis. The method includes the steps of receiving image data and, if necessary, converting it to a digital format. Once the data is in pixel-by-pixel form, each pixel is assigned a slope value derived from the direction of the structure edge, if any, on which it lies. The pixel-slope data is then evaluated to determine whether a photo-resist anomaly is present. The method may also include evaluated an average pixel slope value for each inspected wafer. Dependant claims further define the invention to claim an inspection system for employing the method.

摘要： A first request is sent from a station to an access point. The station receives a first response from the access point that includes a first sequence number, and stores the first sequence number. The station sends a second request to the access point and sets a waiting period for receiving a response from the access point. The station receives a second response from the access point and a third response from a second access point during the waiting period. The second response includes a second sequence number and the third response includes a third sequence number. The station determines that the second response is a legitimate response by comparing the second and third sequence numbers to the first sequence number.

摘要： A system and method for performing optical inspection of structures on the surface of a semiconductor wafer. The wafer surface is illuminated with a polychromatic light source. A multiple-charged couple-device (CCD) camera is positioned to capture light diffracted by the structures on the wafer surface at the first order of diffraction. The captured light is then separated into a plurality of component wavelengths which are directed onto the CCDs. A digital filter creates a plurality of digitized diffractive images of the wafer surface at different component wavelengths. The diffractive images may be integrated and analyzed to detect defects in the structures, or may be, analyzed individually. An image at a particular wavelength may be selected and analyzed by using the known grating pitch of the structures to calculate the wavelength.
