An Embedded Silicon-Carbon S/D Stressor CMOS Integration on SOI with Enhanced Carbon Incorporation by Laser Spike Annealing
We report a CMOS-compatible embedded silicon-carbon (eSiC) source/drain stressor technology with NMOS performance enhancement. The integration includes up to 2.6% substitutional carbon (Csub) epitaxial Si:C and laser spike annealing (LSA) for increased Csub incorporation. 26% channel resistance (Rch) reduction and 11% Idlin-Ioff enhancement for 0.5% Csub and 60% Rch reduction for 2.2% Csub are demonstrated.
