Abstract:
1. A tunnel field effect transistor device made of at least following layers: a highly doped drain layer made of a drain semiconductor material; a highly doped source layer, oppositely doped with respect to the drain layer, made of a source semiconductor material; a channel layer made of a lowly doped or undoped channel semiconductor material situated in between the source and the drain layer; a gate structure comprising a gate dielectric layer and a gate electrode layer, the gate dielectric layer extending along the source layer and the gate electrode layer extending along the gate dielectric layer along a face of the gate dielectric layer opposing the face of the gate dielectric layer facing the source layer and not extending beyond the gate dielectric layer; and a highly doped, pocket layer extending in between and along the gate dielectric layer and the source layer, wherein the pocket layer extends between and along the source layer and the channel layer, and wherein the source layer, the pocket layer, the channel layer and the drain layer are substantially planar and positioned on top and along each other.
