摘要:
A memory-cell array includes a substrate forming parallel first and second trenches. A transistor's upper source/drain region adjoins two of the first and two of the second trenches, and lies above its lower source/drain region. A conductive structure in a first trench associated with the transistor adjoins the upper source/drain region at its first edge. An insulating structure in the associated first trench insulates the conductive structure from a second edge and from a bottom of the associated first trench. A word line, on which is a further insulating layer, is over the upper/source drain region and parallel to the associated first trench bulges into the second trenches. Insulating spaces adjoin the word line laterally. A contact on the conductive structure and in electrical communication with the upper source/drain region connects with a capacitor.

A first capacitor electrode of the capacitor, which is arranged on a surface of a substrate (1), has a lower part (T) and a lateral part (S) arranged thereon. At least a first lateral area of the lateral part (S) is undulatory in such a way that it has bulges and indentations alternately which are formed along lines each running in a plane parallel to the surface of the substrate (1). The lateral part (T) can be produced by depositing conductive material in a depression (V) which is produced in a layer sequence whose layers are composed alternately of a first material and a second material and in which the first material is subjected to wet etching selectively with respect to the second material down to a first depth. The first capacitor electrode is provided with a capacitor dielectric (KD). A second capacitor electrode (P) adjoins the capacitor dielectric (KD).

The capacitor is arranged on the surface of a substrate. A first capacitor electrode has a middle part and a side part, which point vertically upwards, are arranged beside each other and are connected with each other via an upper part located above said middle part and said side part. The middle part is longer than the side part and is connected with other components of the circuit configuration located below said middle part and said side part. The first capacitor electrode is provided with a capacitor dielectric. A second capacitor electrode borders the capacitor dielectric.
摘要:
Bit lines are arranged in the lower parts of trenches of a substrate. Word lines are located above the substrate except for protuberances or bulges, which extend downwards into the trenches and which are arranged above the bit lines. The transistors are vertical transistors whose source/drain regions are located below the word lines and between adjacent trenches. The capacitors are linked with the upper source/drain regions. Conductive structures that surround the word lines from the top and the sides while being insulated from the word lines and bordering on the upper source/drain regions can link the upper source/drain regions with the capacitors.
摘要:
The bottom and the sides of a lower part of recess formed in the substrate has an insulating structure. A first part of the conductive structure of a first electric conductivity type is located in the lower part of the recess. A second part of the conductive structure of a second electric conductivity type, lower than the first type, is located in an upper part and borders the region of the substrate at the sides of the recess. The conductive structure has a diffusion barrier between its first and second parts. The conductive structure is configured as a bit line of a DRAM cell configuration with a vertical transistor, whereby S/Du represents the lower source/drain area and S/Do represents the upper source/drain area connected to a memory capacitor. Or, the conductive structure is configured as a memory capacitor and the upper source drain/area is connected to a bit line.
