  • Publication number: 20150072480
    Abstract: Among other things, one or more systems and techniques for defining one or more implant regions or for doping a semiconductor arrangement are provided. A first implant region is defined based upon a first implant mask overlaying a first active region of a semiconductor arrangement. A second implant region is defined based upon the first implant mask and a second implant mask overlaying a second active region of the semiconductor arrangement. A third implant region is defined based upon the second implant mask overlaying a third active region of the semiconductor arrangement. One or more doping processes are performed through the first implant mask and the second implant mask to dope the semiconductor arrangement. Because the first implant mask and the second implant mask overlap the second active region, doping area coverage is improved thus mitigating undesirable voltage threshold variations otherwise resulting from inadequate doping area coverage.

  • Publication number: 20150050810
    Abstract: A method for ameliorating corner rounding effects in a photolithographic process is provided. A semiconductor workpiece having an active device region is provided, and a photoresist layer is formed over the semiconductor workpiece. A mask is provided for patterning for the photoresist layer, wherein the mask comprises pattern having a sharp corner associated with the active device region. The sharp corner is separated from the active device region by a first distance in a first direction and a second distance in a second direction, wherein the first distance meets a minimum criteria for the photolithographic process, and wherein the second distance is greater than the first distance. The photoresist layer is then exposed to a radiation source, and the radiation source patterns the photoresist layer through the mask, defining an exposure region on the semiconductor workpiece having a rounded corner associated with the sharp corner.

  • Patent number: 8853771
    Abstract: A superjunction device in which corner portions of each annular-shaped second trench are composed of a plurality of alternately arranged first sides and second sides. The first sides are parallel to a plurality of parallel arranged first trenches in a current-flowing area, while the second sides are perpendicular to the first sides and the first trenches. Such design ensures that Miller indices of sidewalls and bottom face of any portion of each second trench belong to the same family of crystal planes. Moreover, with this design, the corner portions of the second trenches can be filled with a silicon epitaxial material at the same rate with the rest portions thereof, which ensures for the second trenches to be uniformly and completely filled without any defects in the corner portions and hence improve the performance of the superjunction device.
