Abstract
The current disclosure describes a new vertical tunnel field-effect transistor (TFET). The TFET includes a source layer over a substrate. A first channel layer is formed over the source layer. A drain layer is stacked over the first channel layer with a second channel layer stacked therebetween. The drain layer and the second channel layer overlap a first surface portion of the first channel layer. A gate structure is positioned over the channel layer by a second surface portion of the channel layer and contacts a sidewall of the second channel layer.
