  • Patent number: 7683948
    Abstract: A system and method is provided for processing a digital image. The system and method processes image data by replacing bad pixel data in the digital image. Specifically, the system and method replaces bad pixel data in the image data by comparing each pixel to selected neighboring pixels, including pixels of other colors in some cases, and determining if the pixel is likely corrupt, such as from a detective pixel. Corrupted pixels are then replaced using averages, means, maximums, or other statistical functions of select nearby pixels.

The bumps (42, 72, 82) are desirably spaced apart by the minimum allowable bump (42, 72, 82) pitch (Lm). Typically, each device cell (43, 73, 83, 93) contains one or more active device regions (44, 74, 86, 96) depending on the overall function. Complex devices (40, 70) are formed by an X-Y array of the clusters (46), where adjacent clusters (46) may share bumps (43, 73, 83, 93) and/or device cells (43, 73, 83, 93). In a preferred embodiment, the bumps (42, 82) form the outer perimeter (48) of the device (40, 80, 90). The maximum device temperature and overall noise is reduced.

  • Patent number: 7681106
    Abstract: A method of error correction includes retrieving raw data from a memory device during a first operational phase of the error correction device. The raw data is retrieved by a bus interface device that interfaces with a variety of memory devices. During a second operational phase, the raw data is outputted from the bus interface device to the bus master. In addition, error correction data is calculated, and error correction is performed on the raw data during the second operational phase. By retrieving the raw data before performing error correction, and by outputting the raw data during the same operational phase, data may be retrieved from the memory more rapidly.

  • Patent number: 7678698
    Abstract: A semiconductor device has at least two tensile stressor layers that are cured with UV radiation. A second tensile stressor layer is formed after a first stressor layer. In some examples, the tensile stressor layers include silicon nitride and hydrogen. In some examples, the second tensile stressor layer has a greater shrinkage percentage due to the curing than the first tensile stressor layer. In one form, the second tensile stressor layer after the curing exerts a greater tensile stress than the first tensile stressor layer. The tensile stressors layers are utilized to improve carrier mobility in an N-channel transistor and thus enhance transistor performance. In one form a single group of overlying tensile stressor layers is provided with each layer being increasingly thicker and having increasingly more hydrogen prior to being cured. In other embodiments multiple overlying groups are formed, each group having a similar repeating depth and hydrogen profile.
