    Abstract: A static random access memory cell is provided that includes first and second inverters formed on a substrate each having a pull-up and pull-down transistor configured to form a cell node. Each of the pull-down transistors of the first and second inverters resides over first regions below the buried oxide layer and having a first doping level and applied bias providing a first voltage threshold for the pull-down transistors. A pair of passgate transistors is coupled the cell nodes of the first and second inverters, and each is formed over second regions below the buried oxide layer and having a second doping level and applied bias providing a second voltage threshold for the passgate transistors. The first voltage threshold differs from the second voltage threshold providing electrical voltage threshold control between the pull-down transistors and the passgate transistors.

    Abstract: An interconnection level of conductive lines and connecting vias separated by insulation for integrated circuits and substrate carriers for semiconductor devices using dual damascene with only one mask pattern for the formation of both the conductive lines and vias. The mask pattern of conductive lines contains laterally enlarged areas where the via openings are to formed in the insulating material. After the conductive line openings with laterally enlarged areas are created, the openings are filled with a conformal material whose etch selectivity is substantially less than the etch selectivity of the insulating material to the enchant for etching the insulating material and whose etch selectivity is substantially greater than the insulating material to its enchant. The conformal material is anisotropically etched to form sidewalls in the enlarged area and remove the material between the sidewalls but leave material remaining in the parts of the conductive lines openings. The sidewalls serve as self aligned mask for etching via openings. The conformal material is either a conductive material which is left in place after the via openings are formed or an insulating material which is removed. In the former, the partially filled conductive line openings are filled with additional conductive material along with the via, which is either the same or different conductive material. In the latter, the conductive line openings and vias are filled with the same conductive material.

One fabrication method comprises the steps of forming an NMOS transistor and a PMOS transistor adjacent the NMOS transistor in a channel width direction, the PMOS transistor and the NMOS transistor separated by an isolation region. A compressive stress liner is deposited overlying the transistors and the isolation region and is etched to remove the compressive stress liner from the NMOS transistor and from a portion of the isolation region. A tensile stress liner is deposited overlying the transistors, the isolation region, and the compressive stress liner and is etched to remove a portion of the tensile stress liner overlying a portion of the compressive stress liner and to leave the tensile stress liner overlying the NMOS transistor, the isolation region, and a portion of the compressive stress liner.

    Abstract: The present invention is directed to a method of forming halo implant regions in a semiconductor device. In one illustrative embodiment, the method comprises forming a gate electrode above a semiconducting substrate, the substrate being doped with a first type of dopant material, and forming halo implant regions in the substrate adjacent the gate electrode by performing at least the following steps: performing a first angled implant process using a dopant material that is of a type opposite to the first type of dopant material and performing a second angled implant using a dopant material that is of the same type as the first type of dopant material. The method concludes with performing at least one additional implantation process to further form source/drain regions for the device.
