Abstract:
1. A microelectronic device, comprising: a non-planar transistor gate over a non-planar transistor fin, wherein the non-planar transistor gate comprises a gate electrode recessed between gate spacers and a capping structure disposed on the recessed gate electrode between the gate spacers, a silicon-containing source/drain region; at least one dielectric material layer over the source/drain region, the non-planar transistor gate spacers, and the capping structure; a source/drain contact extending through a portion of the at least one dielectric material layer and comprising a conductive contact material and a titanium-containing contact interface layer disposed between conductive contact material and the silicon-containing source/drain region; and a titanium silicide interface disposed between the silicon-containing source/drain region and the titanium-containing contact interface layer.
