  • Patent number: 8847205
    Abstract: By reducing a deposition rate and maintaining a low bias power in a plasma atmosphere, a spacer layer, for example a silicon nitride layer, may be deposited that exhibits tensile stress. The amount of tensile stress is controllable within a wide range, thereby providing the potential for forming sidewall spacer elements that modify the charge carrier mobility and thus the conductivity of the channel region of a field effect transistor.

  • Patent number: 8835209
    Abstract: When forming sophisticated semiconductor devices including complementary transistors having a reduced gate length, the individual transistor characteristics may be adjusted on the basis of individually provided semiconductor alloys, such as a silicon/germanium alloy for P-channel transistors and a silicon/phosphorous semiconductor alloy for N-channel transistors. To this end, a superior hard mask patterning regime may be applied in order to provide compatibility with sophisticated replacement gate approaches, while avoiding undue process non-uniformities, in particular with respect to the removal of a dielectric cap layer.
