  • Publication number: 20080108551
    Abstract: The invention generally provides compositions and methods that promote wound healing. Such compositions comprise isolated L. sericata polypeptides having serine protease activity. Desirably, the serine protease degrades fibronectin. The invention further provides biologically active fragments of fibronectin that promote wound healing that are the degradation products of incubation with ES.

  • Publication number: 20080102583
    Abstract: A transistor integration process provides a damascene method for the formation of gate electrodes and gate dielectric layers. An interlayer-dielectric film is deposited prior to the gate electrode formation to avoid the demanding gap fill requirements presented by adjacent gates. A trench is formed in the interlayer-dielectric film followed by the deposition of the gate material in the trench. This process avoids the potential for damage to high-k gate dielectric layers caused by high thermal cycles and also reduces or eliminates the problematic formation of voids in the dielectric layers filling the gaps between adjacent gates.

  • Patent number: 7259083
    Abstract: The present invention is directed to a method of fabricating a local interconnect. A disclosed method involves forming two separate cavities in the ILD above two electrical contacts of a transistor. A first cavity extend down to an underlying etch stop layer. The first cavity is then filled with a protective layer. The second cavity is then formed adjacent to the first cavity and extends down to expose the underlying etch stop layer. The protective layer is removed to form an expanded cavity including the first and second cavities which expose the underlying etch stop layer in the expanded cavity. The etch stop material in the expanded cavity is also removed to expose an underlying gate contact and expose one of a source or drain contact. The gate contact is then electrically connected with one of the exposed source or drain contacts to form a local interconnect.

  • Publication number: 20070066538
    Abstract: An isolated protein, for use in treatment of wounds, is characterized in that it is secreted by the organism Lucilia sericata and it exhibits proteolytic activity against FITC-casein at a pH of 8.0 to 8.5. The protein exhibits proteolytic activity against Tosyl-Gly-Pro-Arg-AMC but not against Suc-Ala-Ala-Phe-AMC, and its proteolytic activity against FITC-casein and Tosyl-Gly-Pro-Arg-AMC is inhibited by the serine proteinase inhibitors PMSF and AMPSF. The protein is also bound by immobilized aminobenzamidine.

  • Publication number: 20070048951
    Abstract: Dielectric gratings are formed between the word line stacks. Spacers are applied to the sidewalls of the word line stacks and the dielectric gratings. In the openings between the spacers, silicon is epitaxially grown on the upper surfaces of source/drain regions, which are implanted self-aligned to the word line stacks. A silicide is formed on the grown silicon, and a metal layer is applied and structured to form local interconnects, which connect the source/drain regions to upper bit lines.
