    摘要: In sophisticated semiconductor devices, different threshold voltage levels for transistors may be set in an early manufacturing stage, i.e., prior to patterning the gate electrode structures, by using multiple diffusion processes and/or gate dielectric materials. In this manner, substantially the same gate layer stacks, i.e., the same electrode materials and the same dielectric cap materials, may be used, thereby providing superior patterning uniformity when applying sophisticated etch strategies.

    摘要: A method of forming a semiconductor structure comprises providing a semiconductor substrate comprising a first transistor element and a second transistor element. Each of the first transistor element and the second transistor element comprises a gate electrode. A stressed material layer is deposited over the first transistor element and the second transistor element. The stressed material layer is processed to form from the stressed material layer sidewall spacers adjacent the gate electrode of the second transistor element and a hard mask covering the first transistor element. A pair of cavities is formed adjacent the gate electrode of the second transistor element. A pair of stress-creating elements is formed in the cavities and the hard mask is at least partially removed.

    摘要: In a multiple gate transistor, the plurality of Fins of the drain or source of the transistor are electrically connected to each other by means of a common contact element, wherein enhanced uniformity of the corresponding contact regions may be accomplished by an enhanced silicidation process sequence. For this purpose, the Fins may be embedded into a dielectric material in which an appropriate contact opening may be formed to expose end faces of the Fins, which may then act as silicidation surface areas.
