Abstract:
1. A method of fabricating a field-effect transistor comprising: forming an oxide layer on the semiconductor substrate; performing a pocket implantation through the oxide layer to the semiconductor substrate; thereafter forming a polysilicon layer on the oxide layer; and patterning the polysilicon layer to form a polysilicon gate, wherein patterning the polysilicon layer to form the polysilicon gate occurs after performing the pocket implantation, and wherein patterning the polysilicon layer to form the polysilicon gate includes patterning the polysilicon layer to form a polysilicon dummy gate electrode, and wherein performing the pocket implantation to the semiconductor substrate forms an implanted pocket in the semiconductor substrate, wherein the implanted pocket extends continuously within the semiconductor substrate from at least a first sidewall of the polysilicon dummy gate electrode to at least an opposing second sidewall of the polysilicon dummy gate electrode.
