A method for producing a tunnel field-effect transistor (TFET) having a source region, a channel region, and a drain region includes arranging an epitaxial layer on a silicon substrate; applying a gate arrangement having a gate electrode to the epitaxial layer, a gate dielectric being arranged between the gate electrode and the silicon substrate; forming a doped pocket region below the gate dielectric adjacent to the source region; forming a selectively silicidated region in the source region, the selectively silicidated region extending as far as to below a gate; and forming a counter-doped region doped in an opposite way to the pocket region adjacent to the pocket region in the source region by diffusion of dopants out of the silicidated region, as a result of which a tunnel junction parallel to the electric field lines of the gate electrode is achieved.
