  • Patent number: 8247282
    Abstract: In sophisticated transistor elements, long-term threshold voltage shifts in transistors comprising a threshold adjusting semiconductor alloy may be reduced by reducing the roughness of an interface formed between the threshold adjusting semiconductor material and the gate dielectric material. To this end, a portion of the threshold adjusting semiconductor material may be oxidized and may be removed prior to forming the high-k dielectric material.

  • Patent number: 8241977
    Abstract: In sophisticated transistor elements, enhanced profile uniformity along the transistor width direction may be accomplished by using a gate material in an amorphous state, thereby reducing channeling effects and line edge roughness. In sophisticated high-k metal gate approaches, an appropriate sequence may be applied to avoid a change of the amorphous state prior to performing the critical implantation processes for forming drain and source extension regions and halo regions.

  • Patent number: 8198147
    Abstract: In a replacement gate approach for forming high-k metal gate electrodes in semiconductor devices, a tapered configuration of the gate openings may be accomplished by using a tensile stressed dielectric material provided laterally adjacent to the gate electrode structure.

  • Patent number: 8198166
    Abstract: A spacer structure in sophisticated semiconductor devices is formed on the basis of a high-k dielectric material, which provides superior etch resistivity compared to conventionally used silicon dioxide liners. Consequently, a reduced thickness of the etch stop material may nevertheless provide superior etch resistivity, thereby reducing negative effects, such as dopant loss in the drain and source extension regions, creating a pronounced surface topography and the like, as are typically associated with conventional spacer material systems.
