Abstract: A transistor structure is formed to include a substrate and, overlying the substrate, a source; a drain; and a channel disposed vertically between the source and the drain. The channel is coupled to a gate conductor that surrounds the channel via a layer of gate dielectric material that surrounds the channel. The gate conductor is composed of a first electrically conductive material having a first work function that surrounds a first portion of a length of the channel and a second electrically conductive material having a second work function that surrounds a second portion of the length of the channel. A method to fabricate the transistor structure is also disclosed. The transistor structure can be characterized as being a vertical field effect transistor having an asymmetric gate.

Abstract: In a replacement gate scheme, a continuous material layer is deposited on a bottom surface and a sidewall surface in a gate cavity. A vertical portion of the continuous material layer is removed to form a gate component of which a vertical portion does not extend to a top of the gate cavity. The gate component can be employed as a gate dielectric or a work function material portion to form a gate structure that enhances performance of a replacement gate field effect transistor.

Abstract: An electronic device comprises an insulator, a local first gate embedded in the insulator with a top surface of the first gate being substantially coplanar with a surface of the insulator, a first dielectric layer formed over the first gate and insulator, and a channel. The channel comprises a bilayer graphene layer formed on the first dielectric layer. The first dielectric layer provides a substantially flat surface on which the channel is formed. A second dielectric layer formed over the bilayer graphene layer and a local second gate formed over the second dielectric layer. Each of the local first and second gates is capacitively coupled to the channel of the bilayer graphene layer. The local first and second gates form a first pair of gates to locally control a first portion of the bilayer graphene layer.

Abstract: A device and method for device fabrication includes forming a buried gate electrode in a dielectric substrate and patterning a stack comprising a high dielectric constant layer, a carbon-based semi-conductive layer and a protection layer over the buried gate electrode. An isolation dielectric layer formed over the stack is opened to define recesses in regions adjacent to the stack. The recesses are etched to form cavities and remove a portion of the high dielectric constant layer to expose the carbon-based semi-conductive layer on opposite sides of the buried gate electrode. A conductive material is deposited in the cavities to form self-aligned source and drain regions.
