Abstract
A method of fabricating a semiconductor device includes forming a plurality of semiconductor fins upon a substrate, forming a plurality of epitaxially grown source-drain regions upon the fins, forming a plurality of device gates upon the fins, the device gates disposed between the epitaxially grown source-drain regions, forming a trench exposing at least one epitaxially grown source-drain region, masking at least a portion of the exposed epitaxially grown source-drain region, forming a gate trench exposing at least a portion of a device gate and gate spacer, forming a metallization layer between the epitaxially grown source-drain region and the device gate, selectively recessing the metallization layer, forming a conductive layer upon the metallization layer, and forming a dielectric cap above the conductive layer.
