Abstract
A capacitive element is located in an active region of the substrate and on a front face of the substrate. The capacitive element includes a first electrode and a second electrode. The first electrode is formed by a first conductive region and the active region. The second electrode is formed by a second conductive region and a monolithic conductive region having one part covering a surface of said front face and at least one part extending into the active region perpendicularly to said front face. The first conductive region is located between and is insulated from the monolithic conductive region and a second conductive region.
