By incorporating carbon by means of ion implantation and a subsequent flash-based or laser-based anneal process, strained silicon/carbon material with tensile strain may be positioned in close proximity to the channel region, thereby enhancing the strain-inducing mechanism. The carbon implantation may be preceded by a pre-amorphization implantation, for instance on the basis of silicon. Moreover, by removing a spacer structure used for forming deep drain and source regions, the degree of lateral offset of the strained silicon/carbon material with respect to the gate electrode may be determined substantially independently from other process requirements. Moreover, an additional sidewall spacer used for forming metal silicide regions may be provided with reduced permittivity, thereby additionally contributing to an overall performance enhancement.
