    Abstract: A method for forming a portion of a semiconductor device structure (30) comprises providing a semiconductor-on-insulator substrate having a semiconductor active layer (34), an insulation layer (32), and a semiconductor substrate. A first isolation trench (40) is formed within the semiconductor active layer and a stressor material (42) is deposited on a bottom of the first trench, wherein the stressor material includes a dual-use film. A second isolation trench (44) is formed within the semiconductor active layer, wherein the second isolation trench is absent of the stressor material on a bottom of the second trench. The presence and absence of stressor material in the first and second isolation trenches, respectively, provides differential stress: (i) on one or more of N-type or P-type devices of the semiconductor device structure, (ii) for one or more of width direction or channel direction orientations, and (iii) to customize stress benefits of one or more of a or semiconductor-on-insulator substrate.

    Abstract: Methods for fabricating a stressed MOS device [30] is provided. One method comprises the steps of providing a monocrystalline semiconductor substrate [36] having a surface [32] and a channel [70] abutting the surface. A gate electrode [66] having a first edge [75] and a second edge [85] is formed overlying the monocrystalline semiconductor substrate. The substrate is anisotropically etched to form a first recess [82] aligned with the first edge [75] and a second recess [84] aligned with the second edge [85]. The substrate is further isotropically etched to form a third recess [96] in the substrate extending beneath the channel [70]. The third recess is filled with an expanding material [100] to exert an upward force [101] on the channel and the first [82] and second [84] recesses are filled with a contact material [HO]. Conductivity determining ions are implanted into the contact material [110] to form a source region [130] and a drain region [132] aligned with the first [75] and second edges [85], respectively.
