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 17):
A method of manufacturing a tunnel field-effect transistor (TFET), the method comprising:\n providing a substrate; forming a drift layer on the substrate; applying a first pattern on the drift layer and performing first lithographic processes to remove a portion of the drift layer; forming a source region in a first portion of the substrate, the first portion being an area not covered by the drift layer; forming a tunnel dielectric layer over the source region and the drift layer; depositing a gate electrode material on the tunnel 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 drift layer and the tunnel dielectric layer, forming a gate electrode and exposing at least part of the first portion of the substrate with the source region and a second portion of the substrate; forming a spacer around the gate electrode; and forming a drain region in the second portion of the substrate.
