  • Patent number: 7887822
    Abstract: Provided in the present invention are recombinant peptides and a method for using the peptides in stimulating an immune response against human high molecular weight-melanoma associated antigen (HMW-MAA). The peptides were designed from the identification of regions of structural and amino acid sequence homology between HMW-MAA and the mouse anti-idiotypic monoclonal antibody MK2-23. The method comprises the step of administering to an individual a peptide of the invention in an amount effective to elicit an immune response against HMW-MAA.

  • Patent number: 7872303
    Abstract: At least one gate dielectric, a gate electrode, and a gate cap dielectric are formed over at least one channel region of at least one semiconductor fin. A gate spacer is formed on the sidewalls of the gate electrode, exposing end portions of the fin on both sides of the gate electrode. The exposed portions of the semiconductor fin are vertically and laterally etched, thereby reducing the height and width of the at least one semiconductor fin in the end portions. Exposed portions of the insulator layer may also be recessed. A lattice-mismatched semiconductor material is grown on the remaining end portions of the at least one semiconductor fin by selective epitaxy with epitaxial registry with the at least one semiconductor fin. The lattice-mismatched material applies longitudinal stress along the channel of the finFET formed on the at least one semiconductor fin.

  • Publication number: 20100244103
    Abstract: A CMOS FinFET device and a method of manufacturing the same using a three dimensional doping process is provided. The method of forming the CMOS FinFET includes forming fins on a first side and a second side of a structure and forming spacers of a dopant material having a first dopant type on the fins on the first side of the structure. The method further includes annealing the dopant material such that the first dopant type diffuses into the fins on the first side of the structure. The method further includes protecting the first dopant type from diffusing into the fins on the second side of the structure during the annealing.

  • Publication number: 20100105187
    Abstract: An oxynitride pad layer and a masking layer are formed on an ultrathin semiconductor-on-insulator substrate containing a top semiconductor layer comprising silicon. A first portion of a shallow trench is patterned in a top semiconductor layer by lithographic masking of an NFET region and an etch, in which exposed portions of the buried insulator layer is recessed and the top semiconductor layer is undercut. A thick thermal silicon oxide liner is formed on the exposed sidewalls and bottom peripheral surfaces of a PFET active area to apply a high laterally compressive stress. A second portion of the shallow trench is formed by lithographic masking of a PFET region including the PFET active area. A thin thermal silicon oxide or no thermal silicon oxide is formed on exposed sidewalls of the NFET active area, which is subjected to a low lateral compressive stress or no lateral compressive stress.

  • Patent number: 7682913
    Abstract: A process for making a MCSFET includes providing a first implant through a first side of an elongated stack, and then providing a second implant through a second side of the stack. The first implant has a dose different than the dose of the second implant, so that final dopant concentrations in the first and second sides differ and the transistor has two threshold voltages Vt1, Vt2.

  • Patent number: 7592421
    Abstract: The present invention provides peptide mimics for HLA class II antigens. The peptide mimics were identified by panning phage display peptide libraries with anti-HLA class II monoclonal antibodies. The peptide mimics inhibit the binding of an anti-HLA class II antigen antibody to HLA class II antigen positive cells and also elicit antibodies which can bind to HLA class II antigen positive cells. The identified peptide mimics can be used as immunogens for therapy of diseases related to cells expressing the HLA class II antigen, such as Non-Hodgkins Lymphoma.
