A novel tunnel FinFET equipped with a SiGe/Si heterojunction and a multilayer fin-channel has been experimentally demonstrated. A high-quality SiGe layer is epitaxially grown on a heavily doped Si source as a tunnel junction. A FinFET-like hetero-multilayer channel with a trigate configuration significantly increases the drain current compared with conventional SiGe/Si heterojunction parallel-plate tunnel FETs.
