Abstract :
We investigated n+SiCP stressors formation by C & P implantation with various amorphization techniques and using high temperature laser annealing SPE technique. Both monomer C and molecular C (C7H7) with P4 implant doping was compared as well as with pre-amorphizing implants (PAI) using Ge, Xe or Sb to enhance the Csub level through SPE amorphous layer regrowth. A P dopant activation level of 4E20/cm3 and a Csub level of 1.52% for Sb-PAI+C7+P4 was realized with s strain layer depth of 50 nm using a 1325°C peak laser anneal temperature.
