Abstract: One illustrative method disclosed includes, among other things, forming a gate structure around a fin and above a layer of insulating material, forming a gate spacer adjacent the gate structure and a fin spacer positioned adjacent the fin above the insulating material, the fin spacer leaving an upper surface of the fin exposed, and performing at least one etching process to remove at least a portion of the fin positioned between the fin spacer, the fin having a recessed upper surface that at least partially defines a fin recess positioned between the fin spacer. In this example, the method further includes forming an epi semiconductor material on the fin recess and removing the fin spacer from adjacent the epi semiconductor material while leaving a portion of the gate spacer in position adjacent the gate structure.

Abstract: One method disclosed herein includes, among other things, forming sidewall spacers adjacent opposite sides of a sacrificial gate electrode of a sacrificial gate structure, forming a tensile-stressed layer of insulating material adjacent the sidewall spacers, removing the sacrificial gate structure to define a replacement gate cavity positioned between the sidewall spacers, forming a replacement gate structure in the replacement gate cavity, forming a tensile-stressed gate cap layer above the replacement gate structure and within the replacement gate cavity and, after forming the tensile-stressed gate cap layer, removing the tensile-stressed layer of insulating material.
