    Abstract: Memory cells having a cell capacitor and a cell transistor, which are arranged in a vertical cell structure, are provided in the cell array of a DRAM. By means of a deep implantation or a shallow implantation with subsequent epitaxial growth of silicon, a buried source/drain layer is formed, from which lower source/drain regions of the cell transistors emerge. The upper edge of the buried source/drain layer can be aligned with respect to a lower edge of a gate electrode of the cell transistor, which consequently results in a reduction of a gate/drain capacitance and also a leakage current between the gate electrode and the lower source/drain region. A gate conductor layer structure is applied and there are formed, from the gate conductor layer structure, in a controlled transistor array, gate electrode structures of control transistors and, in the cell array, a body connection structure for the connection of body regions of the cell transistors.

    Abstract: A transistor fin of a fin field-effect transistor is arranged between two contact structures. A gate electrode encapsulating the transistor fin on three sides is caused to recede by means of a nonlithographic process from contact trenches, which define the contact structures, before the formation of the contact structures. A distance a between the gate electrode and the contact structures is not subject to any tolerances due to the overlay of two independent lithographic masks. For a given extent of the gate electrode along the transistor fin, it is possible to minimize a distance A between the contact structures and thereby significantly increase the packing density of a plurality of fin field-effect transistors on a substrate compared with conventional devices.
