    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: Ultra narrow and thin polycrystalline silicon gate electrodes are formed by patterning a polysilicon gate precursor, reducing its width and height by selectively oxidizing its upper and side surfaces, and then removing the oxidized surfaces. Embodiments include patterning the polysilicon gate precursor with an oxide layer thereunder, ion implanting to form deep source/drain regions, forming a nitride layer on the substrate surface on each side of the polysilicon gate precursor, thermally oxidizing the upper and side surfaces of the polysilicon gate precursor thereby consuming silicon, and then removing the oxidized upper and side surfaces leaving a polysilicon gate electrode with a reduced width and a reduced height. Subsequent processing includes forming shallow source/drain extensions, forming dielectric sidewall spacers on the polysilicon gate electrode and then forming metal silicide layers on the upper surface of the polysilicon gate electrode and over the source/drain regions.

    Abstract: The halo implant technique described herein employs a halo implant mask that creates a halo implant shadowing effect during halo dopant bombardment. A first transistor device structure and a second transistor device structure are formed on a wafer such that they are orthogonally oriented to each other. A common halo implant mask is created with features that prevent halo implantation of the diffusion region of the second transistor device structure during halo implantation of the diffusion region of the first transistor device structure, and with features that prevent halo implantation of the diffusion region of the first transistor device structure during halo implantation of the diffusion region of the second transistor device structure. The orthogonal orientation of the transistor device structures and the pattern of the halo implant mask obviates the need to create multiple implant masks to achieve different threshold voltages for the transistor device structures.

    Abstract: The techniques and technologies described herein relate to the automatic creation of photoresist masks for stress liners used with semiconductor based transistor devices. The stress liner masks are generated with automated design tools that leverage layout data corresponding to features, devices, and structures on the wafer. A resulting stress liner mask (and wafers fabricated using the stress liner mask) defines a stress liner coverage area that extends beyond the boundary of the transistor area and into a stress insensitive area of the wafer. The extended stress liner further enhances performance of the respective transistor by providing additional compressive/tensile stress.

    Abstract: Methods of fabricating halo regions are provided. In one aspect, a method is provided of fabricating a first halo region and a second halo region for a circuit device of a first conductivity type and having a gate structure with first and second sidewalls. The first halo region of a second conductivity type is formed by implanting the substrate with impurities in a first direction toward the first sidewall of the gate structure. The second halo region of the second conductivity type is formed by implanting the substrate with impurities in a second direction toward the second sidewall of the gate structure. The first and second halo regions are formed without implanting impurities in a direction substantially perpendicular to the first and second directions.
