    Abstract: Memory cells each 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 and 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 and this 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 body connection plate for the connection of the channel regions is applied to the substrate surface and contact holes are introduced into the body connection plate. Upper source/drain regions of the cell transistors are formed by implantation through the contact holes.

    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.

    Abstract: A memory cell has a vertical construction of a capacitor and a vertical FET arranged above the latter which can be produced with a lower outlay and in a technologically more reliable fashion. This is achieved by virtue of the fact that two first trenches running parallel and having a first depth are etched in the semiconductor substrate. Between the trenches is formed a web, which is connected to the semiconductor substrate at its narrow sides and which is severed at its underside and is separated from the semiconductor substrate. The suspended web is then provided with a closed dielectric. After a filling, the FET is applied and connected to the web as memory node.

    Abstract: A hard mask is produced from spacer structures. The spacer structures are formed from a conformal deposition on elevated structures produced lithographically in a projection process. The conformal deposition is etched back laterally on the elevated structures resulting in the spacer structures. The elevated structures between the spacer structures are subsequently etched away, so that the spacer structures remain in an isolated fashion as sublithographic structures of a hard mask with a doubled structure density compared with that originally produced in lithographic projection. In a regularly disposed two-dimensional array of structures in the hard mask for forming trenches—for instance for trench capacitors—the method achieves a doubling of the structure density in the array. A further iteration step is formed by forming further spacer structures on the first and second spacer structures, thereby achieving an even higher increase in structure density in the hard mask.

    Abstract: A method for etching trenches having different depths on a semiconductor substrate includes providing a mask with first and second openings. The first and second openings are located where corresponding first and second trenches are to be etched. A slow-etch region, made of a slow-etch material, is provided above the substrate at a location corresponding to the second opening. When exposed to a selected etchant, the slow-etch material is etched at a rate less than the rate at which the semiconductor substrate is etched when exposed to the selected etchant.

    Abstract: A growth material that grows selectively on the vertical sidewalls of a vertical device forms sidewall spacers on substantially vertical sidewalls of the vertical device that is disposed on a horizontal substrate surface of a semiconductor substrate. A spacer-like seed liner may be provided on the vertical sidewalls of the vertical device to control selective growth. The vertical device may be a gate electrode of a field effect transistor (FET). With selectively grown sidewall spacers, heavily doped contact regions of the FET may be precisely spaced apart from the gate electrode. The distance of the heavily doped contact regions to the gate electrode does not depend from the height of the gate electrode. Distances of more than 150 nm between the heavily doped contact region and the gate electrode may be achieved so as to facilitate the formation of, for example, DMOS devices.
