ABSTRACT:
The present invention provides a method in which a low-resistance connection between the MOS channel and silicided source/drain regions is provided that has an independence from the extension ion implant process as well as device overlap capacitance. The method of the present invention broadly includes selectively removing outer spacers of an MOS structure and then selectively plating a metallic or intermetallic material on exposed portions of a semiconductor substrate that were previously protected by the outer spacers. The present invention also provides a semiconductor structure that is formed utilizing the method. The semiconductor structure includes a low-resistance connection between the silicided source/drain regions and the channel regions which includes a selectively plated metallic or intermetallic material.
