    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.
