摘要: A method of forming ultra-shallow lightly doped source/drain (LDD) regions of a CMOS transistor in a surface of a substrate includes the steps of providing a semiconductor substrate, providing a gate stack on the semiconductor substrate, performing a low temperature pocket implantation process on the substrate, performing a low temperature co-implanted ion implantation process on the substrate, and/or performing a low temperature lightly doped source/drain implantation process on the substrate.
