Abstract:
1. A semiconductor structure comprising: a dielectric substrate; a fin body on said dielectric substrate, said fin body including a central channel region and first and second end regions flanking the central channel region; a gate electrode on said dielectric substrate and intersecting said channel region of said fin body, said gate electrode including a first surface coextensive with said dielectric substrate, a plurality of sidewalls, and a second surface connected by said sidewalls with said first surface; a cap of a first dielectric material covering said second surface of said gate electrode, said cap including an upper surface and a plurality of sidewalls extending from said upper surface to said second surface of said gate electrode; a cap spacer flanking said sidewalls of said cap, said cap spacer extending vertically from said upper surface of said cap toward said second surface of said gate electrode, and said cap spacer covering 50% to 75% of each of said sidewalls of said cap measured from said upper surface of said cap; and a first sidewall spacer of a second dielectric material underlying said cap spacer and covering said sidewalls of said gate electrode.
