Methods (50) are presented for transistor fabrication, in which first and second sidewall spacers (120a, 120b) are formed laterally outward from a gate structure (114), after which a source/drain region (116) is implanted. The method (50) further comprises removing all or a portion of the second sidewall spacer (120b) after implanting the source/drain region (116), where the remaining sidewall spacer (120a) is narrower following the source/drain implant to improve source/drain contact resistance and PMD gap fill, and to facilitate inducing stress in the transistor channel.
