Abstract: The present application is directed to a method of selectively positioning sub-resolution assist features (SRAF) in a photomask pattern for an interconnect. The method comprises determining if a first interconnect pattern option will result in improved circuit performance compared with a second interconnect pattern option, where the first option is designed to be formed with SRAF and the second option is designed to be formed without SRAF. If it is determined that the first option will result in improved circuit performance, the first pattern option is selected as a target pattern and one or more SRAF patterns are positioned to facilitate patterning of the first pattern option. If it is not determined that the first option will result in improved performance, the second pattern option is selected as a target pattern.

Abstract: A narrow scanning aperture, lens, and mirror are added to a digital camera to enable image or text scanning. A motion sensor on the same face as the scanner aperture provides approximate scan speed data as the scanner aperture is pressed against and manually moved across the document being scanned. Many documents are too large to scan in one strip, in which case multiple strips are scanned. As each strip is scanned, a bit-mapped image of the strip is created in a data buffer. Data from each strip is passed to a final image RAM which, on completion of scanning, holds a bit-mapped image of the entire scanned page, in B/W, gray scale, or color. Multi pass strip align then processes the image data to remove redundant data (from strip overlap) and position skew (from errors in position during the scan), resulting in a more accurate bit-mapped image in final image RAM of the entire scanned page or item. Image compression compresses the bit-mapped image to standard JPEG format for storage on the camera memory card.

Abstract: Exemplary embodiments provide triple-gate semiconductor devices isolated by reverse STI structures and methodologies for their manufacture. In an exemplary process, stacked layers including a form layer over a dielectric layer can be formed over a semiconductor substrate. One or more trenches can be formed by etching through the stacked layers. The one or more trenches can be filled by an active area material to form one or more active areas, which can be isolated by remaining portions of the dielectric layer. Bodies of the active area material can be exposed by removing the form layer. One or more triple-gate devices can then be formed on the exposed active area material. The exemplary triple-gate semiconductor devices can control the dimensions for the active areas and provide less isolation spacing between the active areas, which optimizes manufacturing efficiency and device integration quality.
