Abstract:
A method of providing contact surfaces that includes forming a first mask having an opening to a perimeter of a gate electrode, the first mask having a first protecting portion centrally positioned over the gate electrode within the perimeter, and a second protecting portion of the mask is positioned over metal semiconductor alloy surfaces of source and drain contact surfaces; and recessing exposed portions of metal semiconductor alloy and the gate electrode with an etch. In a following step, the method continues with filling the openings provided by recessing the gate perimeter of the gate electrode, recessing the metal semiconductor alloy adjacent to the gate structure, and the recessed gate electrode adjacent to the metal semiconductor alloy surface of the source and drain contact surfaces with a protecting dielectric material.

Claim (Index 5):
The method of  claim 1 , wherein said recessing comprises an anisotropic etch process.
