Abstract: A process for manufacturing a semiconductor wafer integrating electronic devices and a structure for electromagnetic decoupling are disclosed. The method includes providing a wafer of semiconductor material having a substrate; forming a plurality of first mutually adjacent trenches, open on a first face of the wafer, which have a depth and a width and define walls); by thermal oxidation, completely oxidizing the walls and filling at least partially the first trenches, so as to form an insulating structure of dielectric material; and removing one portion of the substrate comprised between the insulating structure and a second face of the wafer, opposite to the first face of the wafer.
