  • Patent number: 7795644
    Abstract: Semiconductor devices with selective stress memory effect and fabrication methods thereof. The semiconductor device comprises a semiconductor substrate with a first region and a second region. Both the first region and the second region have a first doped region and a second doped region separated by an insulation layer. A PMOS transistor is disposed on the first doped region layer. An NMOS transistor is disposed on the second doped region. A first capping layer is disposed covering the NMOS transistor over the first region. A second capping layer is disposed covering the PMOS transistor over the first region. The thickness of the first capping layer is different from the thickness of the second capping layer, thereby different stress is induced on the PMOS transistor and the NMOS transistor respectively.

  • Patent number: 7141179
    Abstract: The invention describes a method to facilitate the use of low-sensitivity monitoring equipment for detecting and monitoring defects on the surface of semiconductor wafers. The method includes the use of a hydrofluoric acid solution for increasing the dimensions of a defect and the application of a thin-film layer of a metal, such as titanium, for improving the appearance of the defect such that the defect dimensions increase to above 0.1 nanometer, the detection threshold for economical low-sensitivity monitoring equipment.

  • Publication number: 20050287494
    Abstract: A gingival retraction material is prepared using fibrillated fibers to improve viscosity and combining taste-modifying agent, color agent, and kaolin filler to form a paste-like structure having the viscosity ranging from 31.0×106 cP to 71.0×106 cP. The gingival material is injectable into the patient's gingival sulcus to provide a physical active force that widens the patient's gingival sulcus by means of the material viscosity and also to control gingival tissue fluid and hemostasis so as to keep the gingival sulcus dry for further mold impressions.

  • Patent number: 5691216
    Abstract: Alignment structures in gaps between patterned features, such as polysilicon wordlines or metal contacts, have a selective effect on various processes to promote self-alignment. The various processes include ion implants for code programming, formation of via cuts, and the polycide process of forming composite layered gates. The alignment structures improve these processes by having a selective effect during etching, deposition, and ion implants. Thus, in one example, to prepare a ROM array for code programming using the ion implantation process, the alignment structures or ion barrier walls are formed between the plurality of wordlines. These ion barrier walls, typically silicon nitride or silicon dioxide, have a height above the substrate that is greater than the height of the wordlines. When viewed from a direction orthogonal to the substrate, only the ion barrier walls and wordlines are visible.

  • Patent number: 5621697
    Abstract: A high performance and high density integrated circuit includes interbank bitlines and a bank select structure which improve the vertical pitch of the integrated circuit layout and provide the selective access of data stored in the memory cells. The bank select structures includes bank select transistors which are located and oriented adjacent metal-to-diffusion region contacts such that vertical pitch of the layout is improved, thus promoting a higher density memory array. The bank select transistor is also formed such that conductivity is increased and impedance decreased due to a relatively wide channel width. On the substrate, a plurality of bitlines, including interbank bitlines and intrabank bitlines, and a plurality of wordlines are provided to form memory cells. In bank BK.sub.N, each interbank bitline extends into either bank BK.sub.N-1 or BK.sub.N+1 adjacent to bank BK.sub.N. For the selection of a cell or plurality of cells in bank BK.sub.N, bank BK.sub.
