  • Patent number: 7915132
    Abstract: 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.
