    Abstract: In the case of this semiconductor memory having NROM cells, the channel regions of the memory transistors in each case run transversely with respect to the relevant word line, the bit lines are arranged on the top side of the word lines and in a manner electrically insulated from the latter, and electrically conductive cross-connections are present, which are arranged in sections in interspaces between the word lines and in a manner electrically insulated from the latter and are connected to the bit lines in each case in next but one sequence.

    Abstract: PCT No. PCT/DE93/00553 Sec. 371 Date May 10, 1995 Sec. 102(e) Date May 10, 1995 PCT Filed Jun. 24, 1993 PCT Pub. No. WO94/00876 PCT Pub. Date Jan. 6, 1994For the global planarization of a semiconductor circuit or a micromechanical component with a step between a higher-lying region and a lower-lying region, the regions being large in area, it is envisaged to deposit a first layer (50), remove it again in the higher-lying region apart from a rib (50), deposit a second layer (51) and then, in a CMP step, planarize the entire arrangement.

    Abstract: According to the invention, in the production of a semiconductor storage device with stacked capacitor above bit line storage cells, use is made of a chemical mechanical polishing (CMP) process in which at least the transistor-capacitor contact pillars (9) are produced using one CMP step and there is an overall planarised surface before the bit line (10) is produced. Further CMP steps are applied preferably in the production of the transistor-bit line contact pillar (8) of a bit line (10) embedded in a groove and the lower capacitor plate (11) and for the overall planarisation of the cell field and periphery before the circuit is wired.

    Abstract: The memory with a number of memory cells, such as a read-only (ROM) or dynamic random access (DRAM) memory and the like, is a miniaturised mechanical component. An initial insulation layer (2) is applied over the whole of the main surface of a carrier (1), to be covered over the whole surface by an electrically conductive membrane layer (3). The membrane layer (3) is structured to give the initial conductor paths (4) at the expanded sections (5) of the memory cells. The first insulation layer (2) is given an isotropic etching using the structured membrane layer (3) as the etching mask, until a sharp point (10) remains in the centre directly below the expansion (5). All the remaining material of the insulation layer (2) is removed at the under side of the expansion (5) to form the membrane (5). The membrane can be an oxidation of silicon for the required compressive stress.
