Abstract
A semiconductor device is provided with semiconducting sidewall spacers used in the formation of source/drain regions. The semiconducting sidewall spacers also reduce the possibility of suicide shorting through shallow source/drain junctions. Embodiments include doping the semiconducting sidewall spacers so that they serve as a source of impurities for forming source/drain extensions during activation annealing.
