Abstract

During the fabrication of advanced transistors, significant dopant diffusion may be suppressed by performing a millisecond anneal process after completing the basic transistor configuration, wherein a stress memorization technique may also be obtained by forming a strain-inducing area within a sidewall spacer structure. Due to the corresponding void formation in the spacer structure, a high tensile strain component may be obtained in the adjacent channel region.
