    Abstract: A method of forming a silicon-on-insulator semiconductor device including providing a substrate and forming a trench in the substrate, wherein the trench includes opposing side walls extending upwardly from a base of the trench. The method also includes depositing at least two insulating layers into the trench to form a shallow trench isolation structure, wherein an innermost of the insulating layers substantially conforms to the base and the two side walls of the trench and an outermost of the insulating layers spans the side walls of the trench so that a gap is formed between the insulating layers in the trench. The gap creates compressive forces within the shallow trench isolation structure, which in turn creates tensile stress within the surrounding substrate to enhance mobility of the device.

    Abstract: For fabricating a field effect transistor on an active device area of a semiconductor substrate, a gate dielectric and a gate electrode are formed on the active device area of the semiconductor substrate. Antimony (Sb) dopant is implanted into exposed regions of the active device area of the semiconductor substrate to form at least one of drain and source extension junctions and/or drain and source contact junctions. A low temperature thermal anneal process at a temperature less than about 950° Celsius is performed for activating the antimony (Sb) dopant within the drain and source extension junctions and/or drain and source contact junctions. In one embodiment of the present invention, the drain and source contact junctions are formed and thermally annealed before the formation of the drain and source extension junctions in a disposable spacer process for further minimizing heating of the drain and source extension junctions. In another embodiment of the present invention, the drain and source extension junctions and/or the drain and source contact junctions are formed to be amorphous before the thermal anneal process. In that case, a SPE (solid phase epitaxy) activation process in performed for activating the antimony (Sb) dopant within the amorphous drain and source extension junctions and/or the amorphous drain and source contact junctions at a temperature less than about 650° Celsius.

    Abstract: Dopant deactivation of source/drain extensions during silicidation is reduced by forming deep source/drain regions using a disposable dummy gate as a mask, forming metal silicide layers on the deep source/drain regions, removing the dummy gate and then forming the source/drain extensions using laser thermal annealing. Embodiments include angular ion implantation, after removing the dummy gate, to form spaced apart pre-amorphized regions, ion implanting to form source/drain extension implants extending deeper into the substrate than the pre-amorphized regions, and then laser thermal annealing to activate the source/drain extensions having a higher impurity concentration at the main surface of the substrate than deeper into the substrate. Subsequent processing includes forming sidewall spacers, a gate dielectric layer and then the gate electrode.

    Abstract: The invention provides an improved well structure for electrically separating n-channel and p-channel MOSFETs. The invention first forms a shallow well in a substrate. A buried amorphous layer is then formed below the shallow well. A deep well is then formed below the buried amorphous layer. The substrate is then subjected to a rapid thermal anneal to recrystallize the buried amorphous layer. The well structure is formed by the shallow well and the deep well. A conventional semiconductor device may then be formed above the well structure. The buried amorphous layer suppresses the channeling effect during the forming of the deep well without requiring a tilt angle.
