  • Patent number: 8598006
    Abstract: An embedded epitaxial semiconductor portion having a different composition than matrix of the semiconductor substrate is formed with a lattice mismatch and epitaxial alignment with the matrix of the semiconductor substrate. The temperature of subsequent ion implantation steps is manipulated depending on the amorphizing or non-amorphizing nature of the ion implantation process. For a non-amorphizing ion implantation process, the ion implantation processing step is performed at an elevated temperature, i.e., a temperature greater than nominal room temperature range. For an amorphizing ion implantation process, the ion implantation processing step is performed at nominal room temperature range or a temperature lower than nominal room temperature range. By manipulating the temperature of ion implantation, the loss of strain in a strained semiconductor alloy material is minimized.

  • Publication number: 20130221441
    Abstract: Gate electrodes having different work functions can be provided by providing conductive metallic nitride layers having different thicknesses in a replacement gate scheme. Upon removal of disposable gate structures and formation of a gate dielectric layer, at least one incremental thickness conductive metallic nitride layer is added within some gate cavities, while not being added in some other gate cavities. A minimum thickness conductive metallic nitride layer is subsequently added as a contiguous layer. Conductive metallic nitride layers thus formed have different thicknesses across different gate cavities. A gate fill conductive material layer is deposited, and planarization is performed to provide multiple gate electrode having different conductive metallic nitride layer thicknesses. The different thicknesses of the conductive metallic nitride layers can provide different work functions having a range of about 400 mV.

  • Patent number: 8513719
    Abstract: A semiconductor device includes an N type well region in a P type substrate. A source region of a MOSFET is laterally separated from a boundary of the well region, which includes the drain of the MOSFET. An insulated gate of the MOSFET extends laterally from the source region to at least just past the boundary of the well region. A polysilicon layer, which forms a first plate of a capacitive anti-fuse, is insulated from an area of the well region, which forms the second plate of the anti-fuse. The anti-fuse is programmed by application of a voltage across the first and second capacitive plates sufficient to destroy at least a portion of the second dielectric layer, thereby electrically shorting the polysilicon layer to the drain of the HVFET.
