Claim Text:
1. A device including two vertical transistors comprising: a substrate; a polymeric material post on the substrate, the post having a height dimension extending away from the substrate to a top, the post having a first edge and a second edge located opposite the first edge along the height dimension; an inorganic material cap on the top of the post, the cap covering the top of the post, the cap extending beyond the first edge to define a first reentrant profile and extending beyond the second edge to define a second reentrant profile; a conformal conductive gate layer, a first portion of the conformal conductive gate layer defining a first gate located in at least the first reentrant profile, a second portion of the conformal conductive gate layer defining a second gate that is electrically independent from the first gate and located in at least the second reentrant profile; a conformal electrically insulating layer that maintains the first and second reentrant profiles and is in contact with the first gate and the second gate and at least a portion of the substrate; a conformal semiconductor layer including a first portion and a second portion, the first portion of the semiconductor layer maintaining the first reentrant profile and in contact with the conformal electrically insulating layer that is in contact with the first gate, the second portion of the semiconductor layer maintaining the second reentrant profile and in contact with the conformal electrically insulating layer that is in contact with the second gate, the first portion of the semiconductor layer and the second portion of the semiconductor layer being electrically independent from each other; a first electrode and a second electrode associated with the first gate, the first electrode in contact with the first portion of the semiconductor layer and located adjacent to the first edge, a second electrode over the inorganic material cap and in contact with the first portion of the semiconductor layer, the first electrode and the second electrode defining a first channel associated with the first gate of a first transistor; and a third electrode and a fourth electrode associated with the second gate, the third electrode in contact with the second portion of the semiconductor layer and located adjacent to the second edge, a fourth electrode over the inorganic material cap and in contact with the second portion of the semiconductor layer, the third electrode and the fourth electrode defining a second channel associated with the second gate of a second transistor.
