A semiconductor structure and a method of fabricating the same in which strain enhancement is achieved for both nFET and pFET devices is provided. In particular, the present invention provides at least one spacerless FET for stronger strain enhancement and defect reduction. The at least one spacerless FET can be a pFET, an nFET, or a combination thereof, with spacerless pFETs being particularly preferred since pFETs are generally fabricated to have a greater width than nFETs. The at least one spacerless FET allows to provide a stress inducing liner in closer proximity to the device channel than prior art structures including FETs having spacers. The spacerless FET is achieved without negatively affecting the resistance of the corresponding silicided source/drain diffusion contacts, which do not encroach underneath the spacerless FET. |
