Abstract:
1. A semiconductor structure, comprising: (a) a semiconductor substrate comprising a substrate top surface; (b) first and second source/drain (S/D) regions on the semiconductor substrate; (c) a first fin region on the semiconductor substrate, wherein the first fin region is disposed between and in direct physical contact with the first and second source/drain regions; (d) a front gate region on the semiconductor substrate, wherein the front gate region is electrically insulated from the first fin region by a first front gate dielectric region, and wherein the first front gate dielectric region and the first fin region comprise a first common interfacing surface that is essentially perpendicular to the substrate top surface; and (e) a back gate region on the semiconductor substrate, wherein the back gate region is electrically insulated from the first fin region by a first back gate dielectric region, wherein the first back gate dielectric region and the first fin region comprise a second common interfacing surface that is essentially perpendicular to the substrate top surface, wherein the first fin region is sandwiched between the front gate region and the back gate region, and wherein a first back gate capacitance between the back gate region and the first S/D region is at least 1.5 times a first front gate capacitance between the front gate region and the first S/D region.
