Title: Interpolation method for deinterlacing
Inventor: NAM TAEK YOON
IPC: H04N7/01
Filed: 2006-11-02
Abstract: An interpolation method for deinterlacing is provided to improve picture quality by preventing a corner portion at a right-angle pattern from being broken, and obtain a perfect progressive image from an interlace type image source. Correlations among pixels in a window are obtained by symmetrically moving the window with respect to a certain region of upper and lower line image data of pixels to be interpolated(S51). The respective correlations are analyzed to obtain an interpolation direction(S52). If the interpolation direction indicates a slant line directional edge, pixels adjacent to the corresponding window among the upper and lower line image data are inspected to check the presence of the slant line directional edge again(S53). If the slant line directional edge exists, the slant line direction is determined as an interpolation direction, or otherwise, a vertical direction is determined as the interpolation direction(S54,S56). The interpolation target pixels are interpolated by using the determined interpolation direction(S57).

Title: Method for asymmetric sidewall spacer formation
Inventor: FUSELIER MARK B
IPC: H01L21/336
Filed: 2004-06-04
Abstract: A method for asymmetric spacer formation integratable into a manufacturing process for integrated circuit semiconductor devices is presented. The method comprises forming a gate structure (15) over a substrate, and forming a sidewall layer (10) overlying the gate structure and substrate, wherein the sidewall layer comprises a first portion overlying a first sidewall of the gate structure. A photoresist structure (11) is formed adjacent to the first portion, and subjected to an ion beam. The photoresist structure serves to shield at least part of the first portion from the ion beam. During irradiation, the wafer is oriented such that a non-orthogonal tilt angle exists between a path of the ion beam (13, 17) and a surface of the first sidewall. Formation of asymmetric spacers is possible because radiation damage to unshielded sidewall portions permits subsequent etches to proceed at a faster rate.
