    Abstract: 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.

    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.

    Abstract: A two-bits-per-cell flash memory cell is based on a localized trapping storage mechanism. The memory cell may be programmed via a hot hole injection mechanism and erased via a Fowler-Nordheim electron tunneling mechanism. The memory cells are arranged according to a virtual-ground wiring scheme. Gate structures of the memory cells are arranged in columns, and the widths of the columns are essentially equal to the distance between the columns. Bit lines elongate in pairs between the columns of memory cells and connect corresponding impurity regions being associated to one of the columns of memory cells. Separation devices separating the bit lines of each pair of bit lines are formed symmetrically to the edges of the neighboring columns of memory cells. Program cross-talk issues, concerning memory cells sharing the same bit line, may be avoided while memory cell size remains essentially unaffected.

    Abstract: 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.
