Abstract
A capacitive element includes a trench extending vertically into a well from a first side. The trench is filled with a conductive central section clad with an insulating cladding. The capacitive element further includes a first conductive layer covering a first insulating layer that is located on the first side and a second conductive layer covering a second insulating layer that is located on the first conductive layer. The conductive central section and the first conductive layer are electrically connected to form a first electrode of the capacitive element. The second conductive layer and the well are electrically connected to form a second electrode of the capacitive element. The insulating cladding, the first insulating layer and the second insulating layer form a dielectric region of the capacitive element.
