THIN FILM TUNNEL FIELD EFFECT TRANSISTORS HAVING RELATIVELY INCREASED WIDTH

Abstract:

Thin film tunnel field effect transistors having relatively increased width are described. In an example, integrated circuit structure includes an insulator structure above a substrate. The insulator structure has a topography that varies along a plane parallel with a global plane of the substrate. A channel material layer is on the insulator structure. The channel material layer is conformal with the topography of the insulator structure. A gate electrode is over a channel portion of the channel material layer on the insulator structure. A first conductive contact is over a source portion of the channel material layer on the insulator structure, the source portion having a first conductivity type. A second conductive contact is over a drain portion of the channel material layer on the insulator structure, the drain portion having a second conductivity type opposite the first conductivity type.
