    • A dynamic random access memory includes memory cells arranged in rows and columns on the substrate and a plurality of connecting pillars, each associated with a memory cell. A bit line extends above the main area of the substrate and connects to each memory cell of a column. A first word line connects a first set of alternate memory cells of a row by a first subset of the plurality of connecting pillars. The first word line includes first parts arranged offset relative to the first subset of connecting pillars. A strip-shaped second part extends above the main area and adjoins the first parts of the first word line. A second word line connects to a second set of alternate memory cells of the row by a second subset of the connecting pillars. The second word line includes first parts arranged between mutually adjacent first word lines and offset from the second subset of the connecting pillars. Both the first and second word lines thus overlap but do not cover the connecting pillars. A strip-shaped second part extends above the main area in the first direction and adjoins the first parts of the second word line. The second part is above the first word line and the bit line.

    • A depression extends from a main surface of the substrate to the inside of said substrate and has an upper area and an adjacent lower area. A cross-section of the upper area, parallel to the main surface, is provided with at least one corner. A cross-section of the lower area, parallel to the main surface, matches the cross-section of the upper area, particularly in the vicinity the upper area, with the following difference: each corner is rounded, whereby the cross section of the lower area is smaller than the cross-section of the upper area. In order to produce the indentation, the upper area is provided with an auxiliary spacer that is rounded by isotropic etching. The lower area is produced by selectively etching the substrate to form an auxiliary spacer.
