摘要： In semiconductor memories having a surrounding gate configuration, webs, i.e. vertical rectangular pillars made of substrate material, are formed at the surface of a semiconductor substrate and are surrounded by the gate electrodes in a lower region. Conventionally, it is not possible for word lines to make contact with the gate electrodes in the lower region of the webs without at the same time electrically influencing substrate regions at a higher level in the webs or short-circuiting bit lines from their sidewalls, unless complicated methods requiring additional lithography steps are used. A method for the self-aligning, selective contact-connection of the peripheral gate electrodes is performed with the aid of an insulation layer having a smaller layer thickness than the peripheral gate electrodes.

摘要： In semiconductor memories, in particular DRAMs, the memory cells of which have vertical transistors at vertical lands formed from substrate material, gate electrodes are formed as spacers which run around the land. The gate electrodes of adjacent memory cells conventionally have to be retroactively connected to form word lines. It is known to fill spaces between adjacent lands with an oxide, with the result that the spacers are formed directly as word lines but only cover two side walls of a land. Two transistors which are connected in parallel are formed at these side walls instead of a single transistor, since the gate electrode does not run around the land. The invention proposes a method for fabricating a semiconductor memory in which all four side walls of a land are covered by the word lines and at the same time lands of adjacent memory cells are connected to one another by the word lines.

摘要： A bit line configuration for contact-connecting at least one memory cell, in particular a DRAM memory cell, has bit lines disposed above the plane of the memory cell. A first bit line in a first bit line level is disposed below a second bit line in a second bit line level and the second bit line penetrates through the first bit line at at least one location of the first bit line for the purpose of producing a contact with the at least one memory cell at penetration locations. It is thus possible to provide space-saving structures, in particular sub-8F2 structures.

摘要： 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.
