摘要： The present invention comprises a method for forming a semiconducting device including the steps of providing a layered structure including a substrate, a low diffusivity layer of a first-conductivity dopant; and a channel layer; forming a gate stack atop a protected surface of the channel layer; etching the layered structure selective to the gate stack to expose a surface of the substrate, where a remaining portion of the low diffusivity layer provides a retrograded island substantially aligned to the gate stack having a first dopant concentration to reduce short-channel effects without increasing leakage; growing a Si-containing material atop the recessed surface of the substrate; and doping the Si-containing material with a second-conductivity dopant at a second dopant concentration. The low diffusivity layer may be Si1-x-yGexZy, where Z can be carbon (C), xenon (Xe), germanium (Ge), krypton (Kr), argon (Ar), nitrogen (N), or combinations thereof.

摘要： Reverse narrow width effects are provided consistent with reduced spacing between field effect transistors by an impurity or dopant implantation perpendicular to a semiconductor substrate through gaps formed by selective removal of a layer of material deposited to a selected thickness rather than implantation at an angle in accordance with a patterned resist resulting in superior accuracy, controllability and repeatability of the location of the implanted region and avoidance of implantation at undesired locations. A multi-layer structure having at least three component materials which can be removed selectively to each other is preferred for forming the gaps for confining the implantation preferably performed through a layer of one of the component materials which also functions as an etch stop.
