Abstract:
Structures and methods for a tunnel field-effect transistor (TFET). The TFET includes a gate electrode, a source region having a first conductivity type, a drain region having a second conductivity type opposite from the first conductivity type, and a dielectric layer separating the gate electrode from the source region and the drain region. The dielectric layer provides a channel region between the source region and the drain region. The channel region includes a relatively thin tunnel dielectric between the source region and the gate electrode and a relatively thick drift dielectric between the gate electrode and the drain region.

Claim (Index 8):
A method of manufacturing a tunnel field-effect transistor (TFET), the method comprising:\n providing a substrate; forming a first dielectric layer on the substrate; applying a first pattern on the first dielectric layer and performing first lithographic processes to remove a portion of the first dielectric layer; forming a source region in a first portion of the substrate, the first portion being an area not covered by the first dielectric layer; forming a second dielectric layer over the source region and the first dielectric layer; depositing a gate electrode material on the second dielectric layer; applying a second pattern on the gate electrode material and performing second lithographic processes to remove portions of the gate electrode material, the first dielectric layer and the second dielectric layer, exposing at least part of the first portion of the substrate with the source region and a second portion of the substrate; and forming a drain region in the second portion of the substrate.
