    摘要: The present disclosure provides methods and apparatus of fluorine passivation in IC device fabrication. In one embodiment, a method of fabricating a semiconductor device includes providing a substrate and passivating a surface of the substrate with a mixture of hydrofluoric acid and alcohol to form a fluorine-passivated surface. The method further includes forming a gate dielectric layer over the fluorine-passivated surface, and then forming a metal gate electrode over the gate dielectric layer. A semiconductor device fabricated by such a method is also disclosed.

    摘要: A semiconductor device and method for manufacturing a tensile strained NMOS and a compressive strained PMOS transistor pair, wherein a stressor material is sacrificial is disclosed. The method provides for a substrate, which includes a source/drain for an NMOS transistor, and a PMOS transistor. A first barrier layer is formed on the substrate and a first stressor material is formed on the first barrier layer. The first barrier layer is selectively removed from the PMOS transistor. The substrate is flash annealed and the remaining first stressor material and barrier layer is removed from the substrate.

    摘要: A semiconductor device, such as a PMOS transistor, having localized stressors is provided. Recesses are formed on opposing sides of gate electrodes such that the recesses are offset from the gate electrode by dummy spacers. The recesses are filled with a stress-inducing layer. The dummy recesses are removed and lightly-doped drains are formed. Thereafter, new spacers are formed and the stress-inducing layer is recessed. One or more additional implants may be performed to complete source/drain regions. In an embodiment, the PMOS transistor may be formed on the same substrate as one or more NMOS transistors. Dual etch stop layers may also be formed over the PMOS and/or the NMOS transistors.
