ABSTRACT:
An integrated circuit includes at least one capacitor that is formed on a layer provided with at least one first trench. The capacitor, which is provided with a dielectric layer that separates two electrodes, conforms to the shape of the first trench, but leaves a part of the first trench unfilled. A material capable of absorbing stresses associated with the displacements of the walls of the trench is placed in the trench to fill the part of the first trench. A second trench is formed at least partly surrounding the first trench. This second trench is also at least partly filled with a material capable of absorbing stresses associated with the displacements of the walls of the second trench. A void may be included in the stress absorbing material which fills either of the first or second trenches.
