    摘要: A method and a semiconductor device are provided in which respective contact layers having a specific intrinsic stress may be directly formed on respective metal silicide regions without undue metal silicide degradation during an etch process for removing an unwanted portion of an initially deposited contact layer. Moreover, due to the inventive concept, the strain-inducing contact layers may be formed directly on the respective substantially L-shaped spacer elements, thereby enhancing even more the stress transfer mechanism.

    摘要: Semiconductor devices are formed without zipper defects or channeling and through-implantation and with different silicide thicknesses in the gates and source/drain regions, Embodiments include forming a gate on a substrate, forming a nitride cap on the gate, forming a source/drain region in the substrate on each side of the gate, forming a wet cap fill layer on the source/drain region on each side of the gate, removing the nitride cap from the gate, and forming an amorphized layer in a top portion of the gate. Embodiments include forming the amorphized layer by implanting low energy ions.

    摘要: In sophisticated semiconductor devices, a strain-inducing embedded semiconductor alloy may be provided on the basis of a crystallographically anisotropic etch process and a self-limiting deposition process, wherein transistors which may not require an embedded strain-inducing semiconductor alloy may remain non-masked, thereby providing superior uniformity with respect to overall transistor configuration. Consequently, superior strain conditions may be achieved in one type of transistor, while generally reduced variations in transistor characteristics may be obtained for any type of transistors.
