Abstract
One illustrative method disclosed includes, among other things, forming a gate contact opening in a layer of insulating material, performing at least one etching process through the gate contact opening to remove a gate cap layer and to expose the gate structure, selectively growing a metal material that is conductively coupled to an upper surface of the gate structure such that the grown metal material contacts all of the sidewalls of the gate contact opening and an air space is formed between a bottom of the grown metal material and a conductive source/drain structure, and forming one or more conductive materials in the gate contact opening above the grown metal material.
