    Abstract: Semiconductor devices comprising fully and partially depleted SOI transistors with accurately defined monocrystalline or substantially completely monocrystalline silicon source/drain extensions are fabricated by selectively pre-amorphizing intended source/drain extensions, ion implanting dopants into the pre-amorphized regions and laser thermal annealing to effect crystallization and activation of the source/drain extensions. Embodiments include forming a gate electrode over an SOI substrate with a gate dielectric layer therebetween, forming silicon nitride sidewall spacers on the side surfaces of the gate electrode, forming source/drain regions, forming a thermal oxide layer on the gate electrode and on the source/drain regions, removing the silicon nitride sidewall spacers, pre-amorphizing the intended source/drain extension regions, ion implanting impurities into the pre-amorphized regions and laser thermal annealing to crystallize the pre-amorphized regions and to activate the source/drain extensions.

    Abstract: A method of manufacturing a semiconductor device includes forming a gate electrode over a substrate, implanting dopants into the substrate and activating the dopants using laser thermal annealing. During annealing, the laser and substrate are moved relative to one another, and the movement of the laser and the substrate relative to one another does not pause between and during activating one portion of the source/drain regions and activating another portion of the source/drain regions. Each pulse from the laser can respectively irradiate different portions of the source/drain regions, and a spot area of the laser is less than 50 millimeter2.

    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: A semiconductor device and method of manufacture. A liner composed of a high-K material having a relative permittivity of greater than 10 is formed adjacent at least the sidewalls of a gate. Sidewall spacers are formed adjacent the gate and spaced apart from the gate by the liner. The liner can be removed using an etch process that has substantially no reaction with a gate dielectric of the gate.

    Abstract: A method of manufacturing a semiconductor device includes thermal annealing source/drain regions with a laser, measuring a depth of the source/drain regions, and adjusting a parameter of the laser used in the thermal annealing process. After the laser is adjusted, the source/drain regions are laser thermal annealed again until a desired depth of the source/drain regions is obtained. An apparatus for processing a semiconductor device includes a chamber, a laser, a measuring device, and a controller. The semiconductor device is positioned within the chamber for processing. The laser is used to laser thermal anneal the semiconductor device within the chamber. The measuring device measures a depth of source/drain regions in the semiconductor device when the semiconductor device is within the chamber, and the controller receives measurement information from the measuring device and adjusts parameters of the laser.
