Abstract
A device with multiple vertical transistors includes a substrate and an electrically conductive gate structure including first and second edges opposite each other and including first and second reentrant profiles, respectively. A conformal electrically insulating layer maintains the reentrant profiles and is in contact with the gate. A conformal semiconductor layer maintains the reentrant profiles and is in contact with the insulating layer. First and second electrodes are in contact with first and second portions of the semiconductor and adjacent to the first and second reentrant profiles, respectively. A third electrode is in contact with a third portion of the semiconductor on a top of the gate structure. The first and third electrodes and the second and third electrodes define ends of first and second channels of first and second transistors, respectively. First and second lines, extending between the ends of the first and second channels, are not parallel.
