Abstract
An electronic device includes a vertical-support-element with first and second edges having first and second reentrant profiles, respectively. The first reentrant profile includes first conformal semiconductor and dielectric layers, and a conformal conductive top-gate. A first electrode contacts a first portion of the first conformal semiconductor layer over the top of the vertical-support-element. A second electrode, adjacent to the first edge, contacts a second portion of the first conformal semiconductor layer not over the vertical-support-element. The second reentrant profile includes a conformal conductive bottom-gate, and second conformal dielectric and semiconductor layers. A third electrode, adjacent to the second edge, contacts the second semiconductor layer not over the vertical-support-element. A fourth electrode, over the vertical-support-element, contacts the second semiconductor layer. The first and second electrodes define a first semiconductor channel of a top-gate transistor, the third and fourth electrodes define a second semiconductor channel of a bottom-gate transistor.
