Abstract:
The present invention discloses a method including: providing a substrate; forming recessed regions adjacent to both sides of a gate on the substrate; performing an angled co-implant of a species in two steps with two different energies and two different doses into the recessed regions; forming Silicon-Germanium in the recessed regions; forming source/drain extensions adjacent to both sides of the gate with a dopant; and performing an anneal to activate the dopant.
