Abstract
The novel trench capacitors have a constant or increased capacitance. Materials for a second electrode region and if appropriate a first electrode region include a metallic material, a metal nitride, or the like, and/or a dielectric region is formed with a material with an increased dielectric constant. An insulation region is formed in the upper wall region of the trench after the first electrode region or the second electrode region has been formed, by selective and local oxidation.
