Abstract
Fabricating a vertical transistor includes providing a structural polymer layer on a substrate. A patterned inorganic thin film is formed on the structural polymer layer, leaving exposed portions of the structural polymer layer not under the inorganic thin film. Exposed portions of the structural polymer layer and portions of the structural polymer layer between the patterned inorganic thin film and the substrate are removed to form a structural polymer post having an inorganic cap that extends beyond an edge of the structural polymer post defining a reentrant profile. A conformal conductive gate layer and a conformal dielectric layer on the gate layer are formed in the reentrant profile. A conformal semiconductor layer is formed on the dielectric layer. First and second electrodes are formed in contact with a first portion (over the cap) and a second portion (not over the post) of the semiconductor layer.
