Abstract:
A method of forming an integrated circuit (IC) having at least one PMOS transistor includes performing PLDD implantation including co-implanting indium, carbon and a halogen, and a boron specie to establish source/drain extension regions in a substrate having a semiconductor surface on either side of a gate structure including a gate electrode on a gate dielectric formed on the semiconductor surface. Source and drain implantation is performed to establish source/drain regions, wherein the source/drain regions are distanced from the gate structure further than the source/drain extension regions. Source/drain annealing is performed after the source and drain implantation. The co-implants can be selectively provided to only core PMOS transistors, and the method can include a ultra high temperature anneal such as a laser anneal after the PLDD implantation.
