Abstract
In sophisticated semiconductor devices, an asymmetric transistor configuration may be obtained on the basis of a strain-inducing semiconductor alloy. To this end, strain relaxation implantation processes may be performed at the drain side according to some illustrative embodiments, while, in other cases, the deposition of the strain-inducing alloy may be performed in an asymmetric manner with respect to the drain side and the source side of the transistor.
