Abstract

Methods for fabricating an electronic device and electronic devices therefrom are provided. A method includes forming one or more masking layers on a semiconducting surface of a substrate and forming a plurality of dielectric isolation features and a plurality of fin-type projections using the masking layer. The method also includes processing the masking layers and the plurality of fin-type projections to provide an inverted T-shaped cross-section for the plurality of fin-type projections that includes a distal extension portion and a proximal base portion. The method further includes forming a plurality of bottom gate layers on the distal extension portion and forming a plurality of control gate layers on the plurality of dielectric isolation features and the plurality of bottom gate layers.
