Abstract: A transistor device having a conformal depth of impurities implanted by isotropic ion implantation into etched junction recesses. For example, a conformal depth of arsenic impurities and/or carbon impurities may be implanted by plasma immersion ion implantation in junction recesses to reduce boron diffusion and current leakage from boron doped junction region material deposited in the junction recesses. This may be accomplished by removing, such as by etching, portions of a substrate adjacent to a gate electrode to form junction recesses. The junction recesses may then be conformally implanted with a depth of arsenic and carbon impurities using plasma immersion ion implantation. After impurity implantation, boron doped silicon germanium can be formed in the junction recesses.

Abstract: Numerous embodiments of a method and apparatus for laser annealing are disclosed. In one embodiment, a method of laser annealing includes performing one or more annealing processes on one or more portions of a semiconductor device, where one or more annealing processes performed on one or more portions of the semiconductor device are varied based at least in part on the particular portion of the semiconductor device being annealed, and/or on one or more desirable characteristics of the particular portion of the semiconductor device being annealed.

Abstract: A method enables a gas turbine engine compressor including a stator assembly and a rotor assembly to be assembled. The method comprises providing a casing formed from a plurality of rings, and coupling a first of the casing rings around the rotor assembly such that a radially inner surface of the first casing ring is axially aligned with, and radially outward from, a row of rotor blades extending from the rotor assembly. The method also comprises coupling a second of the casing rings to the first casing ring with a fastener assembly, such that the first casing ring radially inner surface facilitates insulating the fastener assembly from the compressor flowpath.

Abstract: The use of a carbon implant, in addition to the conventional fluorine implant, may significantly reduce the transient enhanced diffusion in P-type source drain extension regions. As a result, resistivity may be reduced, and dopant density may be increased, increasing current drive in some embodiments.

Abstract: Complementary metal oxide semiconductor metal gate transistors may be formed by depositing a metal layer in trenches formerly inhabited by patterned gate structures. The patterned gate structures may have been formed of polysilicon in one embodiment. The metal layer may have a workfunction most suitable for forming one type of transistor, but is used to form both the n and p-type transistors. The workfunction of the metal layer may be converted, for example, by ion implantation to make it more suitable for use in forming transistors of the opposite type.

Abstract: A polysilicon structure may be defined on a semiconductor substrate using plasma doping to dope the sidewalls and upper surface of the polysilicon material as well as the source drain extensions. Shortly after plasma doping, the structure may be encapsulated within a suitable capping layer to prevent the removal of the thin surface doped regions during subsequent semiconductor processing.
