  • Patent number: 8921954
    Abstract: A method for providing a semiconductor structure includes forming a sacrificial structure by etching a plurality of trenches from a first main surface of a substrate. The method further includes covering the plurality of trenches at the first main surface with a cover material to define cavities within the substrate, removing a part of the substrate from a second main surface opposite to the first main surface to a depth at which the plurality of trenches are present, and etching away the sacrificial structure from the second main surface of the substrate.

  • Patent number: 8008161
    Abstract: A method for fabricating a capacitor arrangement which includes at least three electrodes is described. The capacitor arrangement is fabricated using a number of lithography methods that is smaller than the number of electrodes. A capacitor arrangement extending over more than two or more interlayers between metallization layers has a high capacitance per unit area and can be fabricated in a simple way is also described. The circuit arrangement has a high capacitance per unit area and can be fabricated in a simple way. An electrode layer is first patterned using a dry-etching process and residues of the electrode layer are removed using a wet-chemical process, making it possible to fabricate capacitors with excellent electrical properties.
