  • Integrated Circuit Device with Well Controlled Surface Proximity and Method of Manufacturing Same
    Publication number: 20130323891
    Abstract: An integrated circuit device and method for manufacturing the integrated circuit device is disclosed. The disclosed method provides improved control over a surface proximity and tip depth of integrated circuit device. In an embodiment, the method achieves improved control by forming a doped region and a lightly doped source and drain (LDD) region in a source and drain region of the device. The doped region is implanted with a dopant type opposite the LDD region.

  • Shared pixel electroluminescent display driver system
    Patent number: 7027013
    Abstract: An electroluminescent display and driving method is provided wherein the rows of pixels are divided into sub-pixel sets and several different sets of sub-pixels are then addressed from within a larger superset of adjacent sub-pixels. The image data for the addressed sub-pixels is averaged with that for adjacent sub-pixels and is applied to the reduced number of larger sub-pixels in sequence. Consequently, for a given sequence of input frame data sets the time average over one frame for a portion of the sub-pixels at any location of the panel is substantially the same as that for a conventionally addressed sub-pixel in a prior art panel.
