    摘要: A method for producing a capacitor having a dielectric and first and second capacitor electrodes in a semiconductor circuit device formed on a semiconductor substrate, includes forming a trench in a layer applied to the substrate. An electrically conductive layer for the second capacitor electrode is deposited inside the trench and at least regionally conformally with side walls thereof. An auxiliary layer acting as a space-holder for the dielectric is conformally deposited inside the trench and on the electrically conductive layer for the second capacitor electrode. An electrically conductive layer for the first capacitor electrode is conformally deposited inside the trench and on the auxiliary layer. The auxiliary layer is at least partially removed to expose a hollow layer in at least a partial region between the two electrically conductive layers for the first and second capacitor electrodes. The dielectric is deposited into the exposed hollow layer between the two electrically conductive layers. A semiconductor memory device and a method for producing the device include producing the capacitor after production of the transistor and metallizing layers associated therewith for connection of the word and bit lines, in a configuration projecting upward from the plane; placing the capacitor in a trench formed inside a contact metallizing layer for the second electrode terminal of the transistor; and setting a depth of the trench to be equivalent to a layer thickness of the metallizing layer.

    摘要: The invention relates to a self-adjusted nonvolatile memory cell, in which a MOS transistor with source and drain regions is incorporated into the surface region of a semiconductor body. The floating gate and the control gate of the MOS transistor are accommodated, overlapping one another, in a recess trench, while the transistor channel is guided laterally in a surface region of the trench.

A gate electrode (4), which is at a floating potential, is electrically insulated from the drain area (2) by a tunneling oxide (5) and from a channel region (9), which is located between the drain area and the source area (2, 3), by a gate oxide (5; 10). It and extends at least over a part of the channel region (9) and a part of the drain region (2) in the source-channel-drain direction. A control electrode (7) is electrically insulated from the gate electrode (4) by a coupling oxide (8).

    摘要: A method for producing a capacitor having a dielectric and first and second capacitor electrodes in a semiconductor circuit device formed on a semiconductor substrate, includes forming a trench in a layer applied to the substrate. An electrically conductive layer for the second capacitor electrode is deposited inside the trench and at least regionally conformally with side walls thereof. An auxiliary layer acting as a space-holder for the dielectric is conformally deposited inside the trench and on the electrically conductive layer for the second capacitor electrode. An electrically conductive layer for the first capacitor electrode is conformally deposited inside the trench and on the auxiliary layer. The auxiliary layer is at least partial removed to expose a hollow layer in at least a partial region between the two electrically conductive layers for the first and second capacitor electrodes. The dielectric is deposited into the exposed hollow layer between the two electrically conductive layers. A semiconductor memory device and a method for producing the device include producing the capacitor after production of the transistor and metallizing layers associated therewith for connection of the word and bit lines, in a configuration projecting upward from the plane; placing the capacitor in a trench formed inside a contact metallizing layer for the second electrode terminal of the transistor; and setting a depth of the trench to be equivalent to a layer thickness of the metallizing layer.
