Abstract
A well of a first conductivity type is insulated from a substrate of the same first conductivity type by a structure of a triple well type. The structure includes a trench having an electrically conductive central part enclosed in an insulating sheath. The trench supports a first electrode of a decoupling capacitor, with a second electrode provided by the well.
