    摘要: Methods, devices and systems for a FinFET are provided. One method embodiment includes forming a FinFET by forming a relaxed silicon germanium (Si1-XGeX) body region for a fully depleted Fin field effect transistor (FinFET) having a body thickness of at least 10 nanometers (nm) for a process design rule of less than 25 nm. The method also includes forming a source and a drain on opposing ends of the body region, wherein the source and the drain are formed with halo ion implantation and forming a gate opposing the body region and separated therefrom by a gate dielectric.

    摘要: A method of fabrication of a metal oxide semiconductor field effect transistor includes first providing a substrate on which a gate structure is formed. Afterwards, a portion of the substrate is removed to form a first recess in the substrate at both ends of the gate structure. Additionally, a source/drain extension layer is deposited in the first recess and a number of spacers are formed at both ends of the gate structure. Subsequently, a portion of the source/drain extension and the substrate are removed to form a second recess in the source/drain extension and a portion of the substrate outside of the spacer. In addition, a source/drain layer is deposited in the second recess. Because the source/drain extension and the source/drain layer have specific materials and structures, short channel effect is improved and the efficiency of the metal oxide semiconductor field effect transistor is improved.
