    摘要: Known techniques to improve metal-oxide-semiconductor field effect transistor (MOSFET) performance is to add a high stress dielectric layer to the MOSFET. The high stress dielectric layer introduces stress in the MOSFET that causes electron mobility drive current to increase. This technique increases process complexity, however, and can degrade PMOS performance. Embodiments of the present invention create dislocation loops in the MOSFET substrate to introduce stress and implants nitrogen in the substrate to control the growth of the dislocation loops so that the stress remains beneath the channel of the MOSFET.

    摘要: A semiconductor device comprises a fin and a metal gate film. The fin is formed on a surface of a semiconductor material. The metal gate film formed on the fin and comprises ions implanted in the metal gate film to form a compressive stress within the metal gate. In one exemplary embodiment, the surface of the semiconductor material comprises a (100) crystalline lattice orientation, and an orientation of the fin is along a direction with respect to the crystalline lattice of the semiconductor. In another exemplary embodiment, the surface of the semiconductor material comprises a (100) crystalline lattice orientation, and the orientation of the fin is along a direction with respect to the crystalline lattice of the semiconductor. The fin comprises an out-of-plane compression that is generated by the compressive stress within the metal gate film.

    摘要: Carbon may be implanted into a p-type silicon channel to form a carbon region in an n-type metal oxide semiconductor (NMOS) transistor. After an annealing process, the implanted carbon may diffuse from the channel into an interface of a gate dielectric layer and the channel. The diffusion may cause an increase in fixed charge at the silicon surface. Thus, the threshold voltage of the NMOS transistor may be reduced.

    摘要: Nanowire structures having wrap-around contacts are described. For example, a nanowire semiconductor device includes a nanowire disposed above a substrate. A channel region is disposed in the nanowire. The channel region has a length and a perimeter orthogonal to the length. A gate electrode stack surrounds the entire perimeter of the channel region. A pair of source and drain regions is disposed in the nanowire, on either side of the channel region. Each of the source and drain regions has a perimeter orthogonal to the length of the channel region. A first contact completely surrounds the perimeter of the source region. A second contact completely surrounds the perimeter of the drain region.
