    摘要: A semiconductor device, such as a PMOS or NMOS device, having localized stressors is provided. Recesses are formed on opposing sides of a gate electrode. A stress-inducing region is formed along a bottom of the recess, and a stressed layer is formed over the stress-inducing region. By having a stress-inducing region with a larger lattice structure than the stressed layer, a tensile strain may be created in a channel region of the semiconductor device and may be suitable for an NMOS device. By having a stress-inducing region with a smaller lattice structure than the stressed layer, a compressive strain may be created in the channel region of the semiconductor device and may be suitable for a PMOS device. Embodiments may be applied to various types of substrates and semiconductor devices, such as planar transistors and finFETs.

    摘要: Methods and structures for forming semiconductor FinFET devices with superior repeatability and reliability include providing APT (anti-punch through) layer accurately formed beneath a semiconductor fins, are provided. Both the n-type and p-type APT layers are formed prior to the formation of the material from which the semiconductor fin is formed. In some embodiments, barrier layers are added between the accurately positioned APT layer and the semiconductor fin. Ion implantation methods and epitaxial growth methods are used to form appropriately doped APT layers in a semiconductor substrate surface. The fin material is formed over the APT layers using epitaxial growth/deposition methods.

    摘要: A multi-gate semiconductor device is formed including a semiconductor substrate. The multi-gate semiconductor device also includes a first transistor including a first fin portion extending above the semiconductor substrate. The first transistor has a first channel region formed therein. The first channel region includes a first channel region portion doped at a first concentration of a first dopant type and a second channel region portion doped at a second concentration of the first dopant type. The second concentration is higher than the first concentration. The first transistor further includes a first gate electrode layer formed over the first channel region. The first gate electrode layer may be of a second dopant type. The first dopant type may be N-type and the second dopant type may be P-type. The second channel region portion may be formed over the first channel region portion.
