  • Patent number: 8192900
    Abstract: A method for patterning a wafer using a phase shifting photolithography that can produce a critical symmetrical 2-dimensional structure such as a magnetic write pole of a magnetic write head. In one aspect of the invention, a photolithographic mask has an opaque portion with narrow, transparent phase shifting regions at either side of the opaque portion. A non-phase shifted region extends beyond the narrow phase shifted portion at either side of the structure. The phase shifted regions are symmetrical about the opaque region so that the image produced on the wafer is completely symmetrical. In another aspect of the invention, a phase shifted region in formed in a transparent medium with non-phase shifted regions at either side of the phase shifted region. The transition between the phase shifted region and non-phase shifted region alone defines a pattern on the wafer, without the need for an opaque structure on the mask.

  • Publication number: 20120045130
    Abstract: In an electronic device and method of matching an image A and an image B, grayscale centers of the image A and the image B are computed. The image A is divided into n equal parts Dk(k=1˜n) according to the grayscale center, and a grayscale density Vk of each part Dk is computed, to acquire n grayscale densities Dk(k=1˜n) which are regarded as feature data u of the image A. Feature data v of the image B are extracted in the similar way. A similarity of a grayscale density Vak selected from the feature data u and the grayscale density Vbk selected from the feature data V, is computed. Thus, n similarities are computed. A similarity ? (n, u, v) of the image A and the image B according to the n similarities.

  • Publication number: 20110149854
    Abstract: A wireless access device communicates with a plurality of customer premised equipments (CPEs) via a network. The wireless access device establishes a plurality of queues and distributes intervals for each of the CPEs. The wireless access device receives packets from the network, obtains one of the intervals corresponding to one of the CPEs with a MAC address being a destination MAC address of one of the received packets, and stores each of the received packets to one of the queues with sequence number being in the obtained interval. The wireless access device transmits the received packets stored in the plurality of queues in the way of one row by one row.

  • Patent number: 7962863
    Abstract: Computer-implemented methods, systems, and computer-readable media for determining a model for predicting printability of reticle features on a wafer are provided. One method includes generating simulated images of the reticle features printed on the wafer using different generated models for a set of different values of exposure conditions. The method also includes determining one or more characteristics of the reticle features of the simulated images. In addition, the method includes comparing the one or more characteristics of the reticle features of the simulated images to one or more characteristics of the reticle features printed on the wafer using a lithography process. The method further includes selecting one of the different generated models as the model to be used for predicting the printability of the reticle features based on results of the comparing step.
