    摘要： The invention relates to a method for producing a capacitor arrangement, and to a corresponding capacitor arrangement, wherein the first insulating layer is formed at the surface of a carrier substrate and a first capacitor electrode with a multiplicity of interspaced first interconnects is produced in said insulating layer. Using a mask layer, partial regions of the first insulating layer are removed for the purpose of uncovering the multiplicity of first interconnects, and after the formation of a capacitor dielectric at the surface of the uncovered first interconnects, a second capacitor electrode is formed with a multiplicity of interspaced second interconnects lying between the first interconnects coated with capacitor dielectric. This additionally simplified production method enables self-aligning and cost-effective production of capacitors having a high capacitance per unit area and mechanical stability.

    摘要： A method produces a vertical field-effect transistor having a semiconductor layer, in which a doped channel region is arranged along a depression. A “buried” terminal region leads as far as a surface of the semiconductor layer. The field-effect transistor also has a doped terminal region near an opening of the depression as well as the doped terminal region remote from the opening, a control region arranged in the depression, and an electrical insulating region between the control region and the channel region. The terminal region remote from the opening leads as far as a surface containing the opening or is electrically conductively connected to an electrically conductive connection leading to the surface. The control region is arranged in only one depression. The field-effect transistor is a drive transistor at a word line or at a bit line of a memory cell array.

    摘要： A field-effect transistor (FET) with local source-drain insulation is described. The FET includes a semiconductor substrate, source and drain depressions, a depression insulation layer, an electrically conductive filling layer, a gate dielectric, and a gate layer. The depression insulation layer is formed at least in bottom regions of the source and drain depressions. The electrically conductive filling layer realizes source and drain regions and fills the source and drain depressions at a surface of the depression insulation layer. The gate dielectric is formed at a substrate surface between the source and drain depressions. The gate layer (is formed at a surface of the gate dielectric. The source and drain depressions have, in an upper region, a widening with a predetermined depth for realizing defined channel connection regions.
